"Creating a corporate culture is a long-term and complex process," says Roan de Bock, who coordinates and evaluates the regular employee surveys as the head of personnel marketing. The surveys are no longer limited to Germany – they are also being conducted for all foreign MR subsidiaries throughout the world in turn. "Conducting the surveys on a continual basis helps us to define our position: time and again it shows us where we stand compared to other companies, what progress we have already made, and what our employees still see as potential for improvement."

The "Great Place to Work" questionnaire generally focuses on central issues such as identifying with the work you do and the company you work for, work-life balance, appreciation, or promoting health. Additionally, MR encourages participants to assess the professional expertise and social competency of their immediate supervisors. Problems which come to light are then resolved at a departmental level.

"At MR there is a sense of family," says Kerstin Faltermeier. The mother of a 3-year-old son has worked in the field of Corporate Communications since 2009. "Here, an employee is a person and not simply a number. I know from personal experience that this isn't always the case, which is why I really appreciate the pleasant working environment." She has no hesitation in mentioning the company's own day care center "Villa Kunterbunt" as well as the flexible working hours and the option of working from home as further benefits of working for MR.

Alexander Koller feels that MR has recognized the signs of the times. "It is very important to get an idea of employees' opinions and to pick up on their suggestions," says the 43-year-old group leader. Koller came to MR as an apprentice in 1987. He later gained experience in other companies before returning in 2009. He is particularly pleased that MR has never cast doubt over Germany as a production location. For this to remain the case, he believes constant change is vital, even if it is not always easy. Roan de Bock agrees. "Together, we are continuing to build on our reputation as a Great Place to Work. The journey is far from over."

The Columbia story: In 2011, following a successful pilot project, a utility active throughout South America replaces its old, conventional dehydrating breathers with 90 MESSKO® MTraB® dehydrating breathers. Transformers in the middle of the rain forest, not far from the Pacific coast. A mostly deserted area. Soldiers guard the remote transformer stations. Temperatures above 40 degrees Celsius and suffocating 90 percent humidity put the technology here to the test.

In this scenario, MESSKO® MTraB® dehydrating breathers make full use of their greatest strengths: as soon as the silica gel within is saturated with liquid, sensor-controlled heating units automatically regenerate its absorption power. Instead of the oil reservoirs typically used in conventional dehydrating breathers, stainless steel filters keep the air clear of insects and dirt particles. Extremely break-proof, temperature-stable Duran glass provides the devices with continuous, reliable protection. The positive outcome of this retrofitting project: previously necessary inspection and maintenance work is now a thing of the past, the customer reduces its operating costs significantly and soon after the project end, Messko receives follow-up orders of the MTraB® dehydrating breathers for Chile and Peru.

Now, switching our focus to Canada: a short time later, MESSKO® MTraB® helps transformers to breathe a little easier in the HVDC transmission transformer stations of a large energy provider based in Winnipeg. And this under enormous temperature fluctuations since in the prairie province of Manitoba, icy winters with five months of permafrost per year are followed by hot summers. Only about a million people inhabit this area that is approximately twice as large as Germany, and Winnipeg itself is one of the coldest cities in the world. This Messko customer provides these far-flung residents with power, which is generated primarily in hydroelectric and steam power plants as well as wind farms. Excess energy is sent to the US via high-voltage long-distance lines.

As part of a retrofitting program, the energy provider equips numerous HVDC transmission transformers with MESSKO® DB200D dehydrating breathers. Using special flanges, the MESSKO® MTraB®-"S-class" connects to any type of transformer. The built-in filter heating systems, which complement the existing silica gel heating system, automatically power up whenever the temperature falls rapidly. These systems prevent condensation from freezing at the transformer outlet and guarantee the continuous exchange of heated inside air with cold outside air. Both of these processes ensure fault-free operation of the transformer stations. The result is a lighthouse project for the Canadian market that has people far outside of Manitoba talking.

TECHNOLOGY: MESSKO® MTraB® Much of the time, conventional dehydrating breathers filled with common silica gel or similar desiccants are still used in transformers, on-load tap-changers and industrial processes. Depending on the application, their absorption power is typically exhausted within three to twelve months. Required periodic visual inspections and the regular replacement of used desiccants increase costs considerably.

The maintenance-free MTraB® dehydrating breather from MESSKO® provides the perfect solution to this problem. The silica gel in its drying chamber is dehydrated by an integrated heating element using sensor control. This minimizes visual checks and eliminates regular, costly desiccant replacement.

Since its market launch, the MTraB® dehydrating breather has been helping MESSKO® customers the world over to substantially reduce the life cycle costs of their transformers. It has set standards in the market and continues to do so today.

Etschwerke Netz AG was among the first to recognize how valuable this is. The largest utility company in South Tyrol supplies 33 municipalities with power in the thousand-square-meter basin of the megaregion Bolzano, Laives and Merano – 140,000 customers draw one billion kilowatt hours per year. In the transformer stations in Bolzano and Naturns, Etschwerke uses six transformers from various manufacturers in a voltage range of 220/66 kV.

To be able to monitor the transformers continuously and reliably based on data evaluated in detail, Etschwerke equipped them with ISM® and consolidated the data in the MR fleet monitoring system. ISM® is a field device which provides the defined data for each transformer. At Etschwerke Netz AG, the ISM® components were either fitted directly into the motor-drive unit, attached to the transformer in a separate housing or installed – decoupled from the transformer – in a control cabinet in the control room. In the new TAPMOTION® ED ISM® motor-drive unit, the intelligence is integrated ex works as standard.

Since then, ISM® has collected all data crucial for operation regarding effective, apparent and reactive power, gas-in-oil, moisture in oil, load current and load voltage, oil level and ambient temperature, tap-changer position and contact wear. Using an IEC transmission protocol, the data reaches a control center where TESSA® makes it visible in bundled form. "Prevention is crucial for us," says project supervisor Stefano Springhetti. "We want to be able to respond before alarms go off or damage occurs. To do this, we require all relevant information processed by intelligent software."

The software provides the asset manager with reliable results and recommended actions. This means lower maintenance costs, minimized risks and disruptions and simple and centralized service and resource scheduling. Various depictions in the TESSA® fleet monitoring system permit a quick check or a detailed review of individual equipment or the entire fleet, as required.

The analysis so far: implementation has progressed smoothly; handling and efficiency are convincing. One reason that the parties responsible at Etschwerke Netz AG have already started working on the expansion of the system.

TECHNOLOGY: TAPMOTION® ED ISM® AND TESSA® As a cost-effective and practice-oriented solution, the new intelligent TAPMOTION® ED ISM® tap-changer motor-drive unit makes asset management and operations management significantly easier. Its Integrated Smart Module ISM® completely monitors individual transformers and serves as a base for MR's innovative TESSA® fleet monitoring system.

All TAPMOTION® ED motor-drive units previously supplied by MR can be retrofitted easily and cost effectively with ISM® as a retrofit module. Of course, there is also the option to add ISM as an individual solution independent of the drive.

TESSA® relies on communication channels that are already in place, such as data lines or existing control systems. Visualization occurs via an integrated web server with ISM® interface without the user needing to install supplementary software packages.

For us, knowledge transfer is much more than a catchword, it is lived reality. Our apprentices, who are provided with the most exceptional technical support, know this just as well as employees affiliated with MR who continue to train and qualify themselves over many years. This can also be confirmed by the more than 14,000 participants from 170 countries who, since 1976, have learned more about on-load tap-changers and the related technology in the course of individually compiled training programs in Regensburg or at the other MR training centers worldwide, whether in German, English, French, Italian or Portuguese, and always with didactically experienced trainers at their side, who take time and thoroughly address questions.

The Regensburg training center occupies 700 square meters. This includes six training rooms, spacious work rooms, an area with control and monitoring systems, as well as a platform for practical work with on-load tap-changers. In addition to 115 tap changers in models from the last 65 years, in some cases equipped with motor-drive units, there are also 42 functioning models, 9 monitoring systems, 23 training models for automation and control and many MESSKO® products.

In the training center, participants are introduced to seven trainers who, taken together, have a total of 125 years of field experience as service technicians. They convey everything worth knowing about tap changers and their functions, in theory and practice, to transformer manufacturers. Operators of transformers can focus their training on the function and maintenance of tap changers and on monitoring.

Demand for energy in India is growing just as fast as the country's population and industrial infrastructure. In the search for a cheap and environmentally-friendly solution to this problem, Power Grid Corporation of India is bundling the transmission of hydroelectric power in a state-of-the-art new ultra-high DC voltage transmission cable. The North-East Agra Line minimizes transmission losses, increasing efficiency and setting new standards in terms of capacity. It transports power more than 1,700 kilometers from sparsely populated regions near the borders with Bangladesh and Nepal to the conurbation of Delhi. Over 90 million people in the city are to be supplied with environmentally-friendly power.

The ultra-high DC voltage transmission cable has a voltage of 800 kilovolts and at 8,000 megawatts has the largest transmission capacity and the largest direct current carrying capacity ever produced. Two converter stations at its source convert the electrical energy from AC to DC and a station installed at its destination transforms it back again. The challenge for Reinhausen Power Composites was to get a special version of its ReCoTec insulators, tailored exactly to the project-specific circumstances, ready for volume production in a very short time scale. The final product is being used in the transformer stations together with a new generation of reactors built by Trench Austria.

RPC produced an innovative solution: Just four gas-filled insulators, almost eleven meters in length, support the reactors anchored on them. This construction is so stable that it can withstand any kind of environmental conditions and even earthquakes with minimal effort. The hydrophobic, self-cleaning surface of the insulators permanently and reliably protects against complications resulting from environmental influences. RPC is providing 40 of these maintenance-free hollow composite insulators for the North-East Agra Line – a technical milestone in the champions league of high DC voltage transmission.


TECHNOLOGY: RECOTEC® HOLLOW COMPOSITE INSULATORS

MR manufactures silicone-coated hollow composite insulators, based on its ROTAFIL® tubes, under the brand name ReCoTec® (Reinhausen Composite Technology). When compared with conventional porcelain insulators, these offer many advantages: They are significantly lighter, resistant to destruction and earthquakes, and demonstrate proven, superlative properties even in heavily contaminated surroundings. Should they fail or be damaged, they are explosion-resistant and do not release any dangerous parts. Innovations, such as conical ReCoTec® insulators, ReCoTec® with integrated fiber-optic cables, and ReCoTec® with flanges made of FRP material, help MR customers expand and secure their market leadership.
