Equipment Description:
SLQ primary injection test set is a high current generator instrument. It is applied in current transformer test , circuit breaker test and so on. Adjustable output current, smooth in current rise, large scope of load variation, easy and safe operation.
The SLQ primary injection tester has two kinds of model. One is
integral box and another is the separated box. The model is depends
on the maximum capacity output of the whole tester. If the
whole capacity of the tester is less or equal to 5KVA, the control
unit and the current booster will
be designed in one single box. Otherwise the control unit will be a
one box and the current booster will be a one box.
Functions and Applications
The main applications and functions of SLQ are as follow:
1) High current output injected to the main circuit of power line
to simulate the fault current.
And then check whether the protection system will be operated
according to the design
2) High current output injected to the primary of current
transformer and then measure the inducted current from secondary by
error measurement instrument to check the ratio error and phase
displacement of CT
3) High current output injected to the main circuit of circuit
breaker to simulate the rated current in primary. And then check
the stability of circuit breaker according to the temperature rise
procedure.
4) Considered as a AC high current source in power equipment or
cable test
