Michael Rohde

Dear Sir or Madam,

Most of us are back from their summer holiday by now. We are going back to work with new enthusiasm. What has changed at REINHAUSEN over the summer? One of our latest challenges was to figure out a way how we could save transformer manufacturers’ time and money, already in the construction phase. Our answer: From now on, if you order a tap-changer at our company, you will receive the corresponding 3-D model of it including drive shafts, on demand and already in advance. This can effect time saving of up to one day. You will find all further information in this issue of INSIGHT. Another breaking news story: our worldwide unique test center in Regensburg has gone into operation, in order to enable us to launch, innovate and practice capable products for your requirements more quickly in the future.

Enjoy reading!

Best regards
Michael Rohde
Managing Director

P.S: Feel free to contact our webmaster at webmaster@reinhausen.com in order to help us to get better every time.

Only test center of its kind in the world opened

Following a spectacular official opening ceremony by the Minister President of Bavaria, our new test center in Regensburg is now operational. At a cost of no less than 25 million Euros, the new high-tech building has no equal anywhere in the world. This is where we subject our tap-changers to ultra-tough tests in high-voltage, power and mechanics laboratories. Nowhere else in the world is it possible to provide such comprehensive simulation of the whole range of loads and stresses to which these devices are exposed over their service lives. Whether it be electrical, mechanical, chemical or climatic loads and stresses, in our test center we have every kind of testing device and method that can possibly be needed.

A few highlights: in our high-voltage laboratories we can generate power-frequency voltage of up to 700,000 V using our test transformers and can therefore simulate the loads associated with real electrical high-voltage power supply systems. Using a voltage pulse generator capable of generating voltage peaks of up to 1.8 V with a rise time of one millionth of a second, the tap-changers are tested for their performance under the impact of lightning strikes. In order to simulate the loads and stresses associated with external temperature influences, we run a range of cold and heat cycles in our temperature chambers. We have two test chambers. Here we can run fully automated load and stress cycles with a speed of change of 1 degree per minute and the application of hydrostatic pressure of up to 2.5 bar within a temperature range of -70°C to +130°C.

Success for the Composite Products Team, 24 June 2008
Siemens Healthcare names MR the supplier of the year

The employees of our Composite Products (CP) Division have reason to celebrate. Dr. Jens Frost was present in Erlangen to accept the award as supplier of the year from Siemens Healthcare. Every year Siemens reviews all suppliers and grades their performances with an elaborate point system. The decision for MR was not only based on the excellent cooperative work but also, even more importantly, on the quick help during development projects. For years now, the Composite Products Division has been supplying processed composite tubes as coil carriers for magnetic resonance tomography devices. These are the devices which allow doctors to look inside the human body.

Award-winning Logistics:
Siemens Transformers awards Supplier Award to MR

Siemens’ Transformers division recently presented the Supplier Award 2006/2007 in the Logistics category for all suppliers worldwide. MR received an award for its outstanding forecast system, while the other awards went to Thyssen Krupp, Asta, Pucaro, Shell and TTP India. The award ceremony took place in the stadium of FC Nuremberg.

Along with the planners at the 20 transformer production plants of the Siemens division, MR had managed to quickly adapt its delivery capability and faithfulness to delivery deadlines to rapidly growing demand. MR tap-changers were the only component for which no changes had to be made to delivery dates for transformers to end customers of Siemens within the period under assessment. Tribute was paid to this logistics performance as an exemplary benchmark in the massive phase of growth.

This performance, however, would not have been possible without our motivated staff whose joint efforts throughout the entire MR logistics chain, from Sales to Materials Management, Assembly and Dispatch, made a lasting contribution to this success. Our special thanks to all the staff involved.

General Manager Michael Rohde, who was there to receive the award with Bernd Behrend (Key Account Siemens) said: “Such recognition from one of our customers makes us proud. However, it is not a cause for self-satisfaction. Instead, we see this award as further motivation. The lasting competitiveness of our customers is our goal.“

Messko - oil level indicator on a transformer in Ternitz
Digital thermometer EPT202 in the substation Ternitz.
Remote Oil Level Check

Oil level indicators on transformer expansion tanks are common items of equipment. There is an increasing need for tank values to be monitored from a distance. The magnetic indicators made by Messko provide the perfect solution. Here the values are converted into process signals, typically 4 – 20 mA, by a TT30 signal converter, making remote interrogation simplicity itself.

The Austrian power supply VERBUND – Austrian Power Grid AG – is already using this solution. MTO-TT indicators, for example, have been installed on the new phase shifters in Ternitz, Tauern and Ernsthofen. These are each comprised of an exciting transformer and a series transformer. In addition to the standard version, shown in the illustration, tilt bracket versions have also been installed. This enables the oil level to be easily read from below. To be on the safe side the values are also sent by data communication to the EPT202, the Messko digital thermometer. This monitors the temperature of the oil and the winding as well, and controls the fans into the bargain.
The illustrations show both of the devices on the phase shifter in Ternitz. This is where the flow of power to the Steiermark, where power consumption is higher than the production, is controlled.
Messko recently started selling three different limit switches for standard oil level indicators, the only company to offer them anywhere in the world. These are either configured to fixed settings at the factory or are optionally freely configurable. One possible use is for maximum oil level, minimum oil level and critical minimum oil level. A trip message is only triggered in the last case. It goes without saying that these three limit switches are also available in combination with tilt brackets and signal converters to enable the oil level to be read on a remote basis as well.
    Overview of the features of the oil level indicator:
  • Tilt bracket, optionally 15°, 30° or 45°
  • 1 – 3 pre-set or freely configurable limit switches
  • TT30 signal converter with 4 - 20 mA output or optionally 0 – 1 mA, 0 - 20 mA or RS485

The Retrofit Kit – Operating in Russia

In the last issue of INSIGHT we told you about our Retrofit Kit. For many industrial firms in the area of the former Council for Mutual Economic Assistance (COMECON) this is a particularly useful innovation. The replacement of a Bulgarian tap-changer with a MR MSE tap-changer provides an example of a simple means of equipping functional and rugged transformers with long lasting tap-changers.

The transformer workshop Diarost in Russia has already benefited from the advantages offered.

At the start of June 2008, as part of a program of modernizing and increasing the capacity of the transformer in a substation in Kazan, the tap-changer was also replaced by an OILTAP® MSE.
In order to gain experience in the field of tap-changer replacement and to be able to react to any possible unforeseen eventualities, the replacement and modification work to the transformer was carried out in a transformer workshop. The replacement was a great success and, thanks to the MR adapter head, there was no need for any structural changes to the bell-type tank. In addition, design adaptations to the OILTAP® MSE tap selector made it possible to connect most of the connecting leads on the tap selector without modifications. Thanks to the fact that the job was completed easily and without a hitch, tap-changers will in future always be replaced on site, which will offer the operator considerable savings both in time and money.

Installation is no problem. Our experts can be contacted at service@reinhausen.com or a.kulkov@reinhausen.ru to answer all your questions.
