Routine Tests as per IS 2026 & IEC 60076

Our products go through a gauntlet of regular Tests & Checks for all parameters as per IS & IEC guidelines to meet the highest quality standards in the industry. We have NABL accredited state-of-the-art testing facilities to carry out different routine, special and type tests as per IS 2026 & IEC 60076. We have an in-house Impulse generator up to 900 kVp with chopping and HV Tester.
