Optimising our quality through frequent testing

Single Sheet Tester MPG100 - SST

Transformer manufacturers strive to design transformers as efficient as possible. In the designing-phase of a transformer, it is very important to minimise the core losses. The most critical parameter in core losses is the loss of iron in electrical steel. We have the possibility to measure iron losses in W/kg on different Tesla levels. Insight in the amount of iron loss in electrical steel is beneficial for the customers, to help them build transformers with more predicatable core losses.

With the SST equipment EMS is able to measure iron losses in line with the international standard IEC 60404-3.


Franklin Tester

Next to the importance of knowing the iron losses it also is important to have maximum coating resistance. Good coating resistance helps the magnetic fluxes will go linear through the electrical steel in the core of a transformer.

With the Franklin Tester, EMS is able to measure coating resistance in line with the international standard IEC 60404-11. The SST and Franklin Test equipment in EMS is calibrated and certified. If agreed with the customer EMS is able to send a full report with results.

It is possible to measure samples made in EMS or samples provided by the customer.
