Megohm insulation testing will only detect faults to ground. The majority of faults will go undetected using this method alone.
Surge testing requires the application of high voltages and currents, which can be destructive and actually generate faults. This aspect combined with the size of surge testing equipment makes it inappropriate for troubleshooting and predictive maintenance testing.
In addition, resistance and inductance-only (RLC) test methods dont provide enough information for reliable fault detection and troubleshooting.
The ALL-TEST PROŽ MOTOR GENIEŽ is your best, most economical choice for fault detection and troubleshooting.
