ERDA - Electrical Research and Development Association
About
The Electrical Research and Development Association is a co-operative industry research body at Makarpura GIDC in Vadodara, Gujarat - the road it stands on is named after it - and its EMI/EMC laboratory is among the better-equipped independent facilities in western India, accredited to ISO/IEC 17025:2017 by NABL. Its anchor facility is a 10 metre semi-anechoic chamber with a 5 metre diameter turntable rated to three metric tonnes and radiated immunity field generation to 60 V/m, which accommodates switchgear assemblies, motors, large UPS and SMPS systems and electric vehicle chargers rather than only bench-scale equipment. Instrumentation is correspondingly serious: EMI test receivers covering 20 Hz to 26.5 GHz, an artificial mains network rated to 100 amperes over 9 kHz to 30 MHz - a rating few Indian laboratories match and the one that makes high-current industrial equipment testable - signal generators and power amplifiers spanning 9 kHz to 22 GHz, and an isotropic electric field probe reading to 800 V/m across 10 kHz to 40 GHz. Two designations distinguish it: approval by Integrated Headquarters, Ministry of Defence (Indian Navy), which opens naval programmes, and TEC accreditation for telecom equipment evaluation. The accredited programme runs MIL-STD-461 revisions E and F for radiated and conducted emission and susceptibility alongside the commercial radio interference, ESD, RF immunity and harmonic measurement standards. Published work spans energy meters, switchgear, motors, rocket launcher assemblies, UPS and SMPS equipment and EV chargers. Specialisations are high-current industrial and switchgear EMC, naval and defence equipment, telecom equipment evaluation, energy metering, and electric vehicle charging infrastructure.
