| 'Olympus' Portable Secondary Injection/Relay Test set is designed for working on 220/230 single phase 50Hz Ac supply and complete with power 'ON-OFF' indicator, circuit 'ON' indicator. The set will have following independent circuits depending upon functional requirement of customer. Each circuit shall have push button actuated, relay/contractor to control the output of the circuit. All these circuits and components shall be housed in Rigid PVC Suitcase with carrying handle or wheels in case of Higher capacity. CURRENT CIRCUIT : To Inject current of desired value in the relay/contactor. This circuit consists of loading transformer, selector switch, variable control, fine adjustment. Depending upon specific requirement percentage selector switch can also be provided to inject current at various multiples. The current injected is indicated by Ampere Meter. For large range the Ammeter has a multiplier or current transformer. VOLTAGE CONTROL : This circuit supplies voltage Independently as per requirement. The continuously variable voltage or fixed tap voltage can be provided as desired by the user. AC or DC or both voltages can be provided along with corresponding metering, indications, switches etc. PHASE SHIFT CIRCUIT : This is incorporated only when special type of relays are to be tested. The phase angle between voltage & current is developed to obtain current operational parameters of the relay. TIME CIRCUIT : Digital Timers with freezing facility is provided for recording the operation/tripping time of relays under test. Each circuit is independent & push button operated, relay/contractor to control the output of the circuit. |
