A good common sense test for low voltage (480 v) capacitor banks. 1> Whenever you walk past a capacitor bank, drag your hand over the cans. If one is defective, it will be cooler than the others. If so, test further. 2> Check currents with a clamp-on ammeter. This will instantly tell if a capacitor is off spec.
The M3628PCF Portable Capacitor Former can be used for maintenance on stored capacitors or as a benchtop DC power supply. The M3628PCF reforms capacitors by allowing the operator to slowly increase the DC voltage in order to allow the internal chemistry of the capacitor to adjust at an appropriate rate. Digital displays indicate the setpoint
Capacitors • Check for physical damage, leaks, bulges, or discoloration. Replace as required. • Clean capacitor case, insulation bushings, and any connectors that are dirty or corroded. • Check each capacitor for capacitive reactance by applying 120 volts to each phase and measuring corresponding current. Verify with specification.
Visually inspect the capacitors. Check the protection fuse. Control the ambient temperature (average of 35 °C In accordance with IEC 60831). Control the service voltage (especially during moments of low load, it must not exceed the nominal +10%)
