Quality is central to the performance & longevity of a transformer. At Sempra Electric, the focus on quality begin with identification of Raw Materials , Regular Inspection, Testing and validation before it taken to the production

To create an excellent environment for production such as dust free winding chambers, systematic core assembly process , indigenously developed and designed autoclaving process to ensure the creation of superior transformer which can measure up to the most rigid inspection checks and tests on sustainable basis.

At Sempra Electric, we believes in quality and always use superior grade for insulation called ABB Sigmacon 3.0 which is generallyused in power transformers and special type of transformers.


Bureau Veritas has certified our management systems, for their conformance to quality standards ISO 9001:2015, ISO 14001:2015, and BS OHSAS 18001:2007, which ensures the quality deliverables in terms of our products & services to our customers.

Transformers designed, manufactured, repaired, and tested by us ranging from 5 KVA to 50 MVA (up to 132 kV class) are in successful operations throughout the length and breathe of India as well as in the above-mentioned countries, as specified by us.


The Process of manufacturing and Repairing of transformer is critically depend on testing of raw materials, components and the final assembled products.

We are equipped with state of art testing facilities to perform all routine tests as well as special tests. We are also equipped to carry out temperature rise measurement on transformers up to 50 MVA.
