Refrigerant Compressor Fault Simulator

The table unit is part of a series designed for training in refrigeration engineering. The unit addresses electrical faults as they can occur in the operation of a commonly available refrigerant compressor. The faults are simulated using pushbuttons on the front panel of the unit. Other components as, a switch box with the starting relay, running capacitor, starting capacitor and motor protection circuit breaker are also arranged on the front panel. The measured points in the electrical circuit are accessed using laboratory sockets. A circuit diagram printed on the front panel provides information on the circuit. A multimeter is included for fault-finding.
