'RE'
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.
