Other Magnetic Products
The principle of this magnetic products are based on Kirhoff current law: algebraic sum of complex current for any flowing point in the circuitis zero. Under normal conditions of circuit and equipments, the vector of various of phase current is zero. Therefore, there is no signal output in the secondary winding group,non operating is implemented. When earthing fault occurs, the vector of phase current is not zero, magnetic flow is produced by by toroidal core in the current transformer, which is caused by fault current.,secondary induced voltage of the transformer will operate, which will drive release components to cut off the power supply network, and reaches its aim of earthing fault protection.
▲ Inspect the small earthing fault differential current among phase contacts connected to neutral.
▲ At near water area, CFCI socket or plug, and arcing circuit breaker(AFCI,GFCI) in air-conditioner.
▲ Inspect the arc caused by cable ignition, over current due to short circuit or too frequent current changing.
▲ RCCB (residual current circuit breaker)
▲ Accurate and stable output
▲ Nearly zero load offset
▲ Good balancing and temperature property
