Megavar is an Australian organisation which specialises in multi-disciplined testing services and commissioning of power systems. Megavar provides all types of primary testing and secondary testing services.
Under primary testing, Megavar provides AC current injection up to 800A, DC current injection up to 400A, AC voltage Hipot up to 120kV (50Hz), AC very low frequency cable testing up to 60kV, operational earth lead testing, hot-stick testing, elevated platform vehicle electrical testing and ducter testing of contact resistance.
Other primary testing services offered by Megavar include power transformer testing for ratio and winding resistance, transline impedance measurement of phase, earth impedance and mutual coupling, circuit breaker timing test which include O, C and OCO, CT testing for ratio, kneepoint, resistance, polarity and burden, VT testing for ratio, phase and polarity and so on.
Apart from primary testing services, Megavar also provides secondary testing services which include testing of overcurrent, earth faults, transformer differential, line differential, high and low impedance bus zone, restricted earth faults, transformer guard relays, distance (impedance) protection and load shedding. Secondary testing provided by Megavar also include capacitor bank controllers, bay controllers, interlocking and autoreclose schemes.
