The Noja Power interface test set uses Rogowski transformers to convert an injected current signal into a voltage signal. When used in conjunction with a power system and three-phase test set, it can be used to conduct three-phase short circuit, phase-to-phase short circuit, earth fault, upstream broken wire, low source voltage and loss of supply tests.
OSM reclosers do not provide discrete inputs for CT connections, making it difficult to introduce a secondary signal to the MPM. To overcome this problem, the test set simulates the current and voltage signals generated by sensors inside an OSM recloser bushing.
The device also has external voltage-free contacts both normally open and normally closed that simulate the positioning of the contacts. The simulator also allows coil faults to be actioned and include mechanical/manual trip, simulator coil short circuit, simulator coil open circuit.
