High Voltage Division(HVD)
The High Voltage Division comprises of the following laboratories for providing services on dielectric testing of all major electrical equipment.
1. The EHV test laboratory (Main laboratory).
2. Pollution laboratory
3. Impulse current test laboratory
The division undertakes quality assurance tests as per national (IS) and International standards, like BS, IEC, ANSI, Canadian standards etc. All the test facilities are of the state of the art type and compare well with the facilities available at other international laboratories like KEMA-Holland, CESI, Italy, IREQ, Canada etc. The laboratory has NABL and ASTA accreditation and serves for Indian customers & customers from abroad.
