Aditya Vidyut Appliances started in 1989. It is situated at Thane, Maharashtra mainly having a business hold over manufacturing transformers. Hence as a result the laboratory set ups are meant to conduct electrical tests on transformers and similar appliances. The tests are aimed at determining voltage ratio and polarity, vector group verification, resistance, impedance and harmonics test, overvoltage, effects on on-load ta changer, impulse tests, noise level, capacitance, dissipation factor and rate of energy consumption, etc. The in house laboratory enabled to check all sorts of properties of the transformers after manufacturing ensures an enhanced level of quality along with safety. Hence preserving consumer requirements with high standards of service delivery since a very long time.
