The Megger S1-568 Insulation Resistance Tester delivers 90-264 V rms of AC voltage at a frequency of 50/60 Hz and 100 A of power, translating to 6 hours of continuous testing at 5 kV with a 100 MΩ load.
The Megger SMRT36 has the "smart" combination of high compliance voltage and high current to test all electromechanical, solid-state and microprocessor-based overcurrent relays, including voltage controlled, voltage restraint and directional overcurrent.
