Global Electrical has a long-standing history when it comes to power transformers and the maintenance and rewind of power transformers. Transformer maintenance can be done at our Transformer repair workshop where we do power transformer rewinding, test winding resistance, any size substation maintenance, transformer testing, transformer oil sampling and transformer frequency response tests. MET is rated for high voltage and low voltage testing and can replace and check transformer oil levels. We have all the necessary equipment to give you a complete data analysis on the transformers winding circuit. We can repair any size transformer.
