Transformers are one of an installation’s most valuable elements, so the evaluation of their condition is essential to achieving optimal commissioning by ruling out any manufacturing, transport or installation failure. Testing is also essential for efficient operation and maintenance over the transformer’s life.
At 4fores, we carry out tests on all types of transformers, whether they are power, current or voltage. We have experienced professionals and use the best measuring and testing instruments.
