Dry-type Current Transformers
Model: LGB
The dry-type current transformer, assembling by a bushing-type primary winding and secondary winding(s).Possessing those advantages of light frame, oil-free, gas-free, porcelain-free, fire-proof and explosion-proof etc, used for current measurement and relay protection in the power system with the rated voltage of 35kV.
Rated voltage is 35kV up to 220kV
Highest voltage for equipment is 40.5kV up to 252kV
Rated primary current is 50A~4000A
Rated secondary current is 5A or 1A
Rated frequency is 50Hz or 60Hz
Rated output: 20VA~40VA (If any other rated output required, we can satisfy it.)
Accuracy classes and their combinations: Steady accuracy classes are 0.2S, 0.2, 0.5S, 0.5, 5P, 10P, PR and PX; transient accuracy classes are TPS, TPX, TPY and TPZ. There are 1~6 pcs secondary winding(s) in a CT.
Instrument security factor (FS) of measuring class is 5 or 10
Accuracy limit factor (ALF) of protective class is 5, 10, 15, 20, 30 or 40
Arcing distance is ≥410mm
Non-effectively earthed neutral system
The frame of the dry-type current transformer is upstanding, its parts which outside of the case are the bushing-type assemblies which made by silicon rubber umbrellas, and there are the primary terminal blocks at the top of the assemblies; The secondary winding(s) are going through the bushing-type primary winding, which put inside the case, there is a secondary terminals box in the obverse of the case; There are 4 pcs lifting eyebolts at the bottom of the case. The main insulation of the dry-type current transformer is made by the new organic composite materials, comparing to the other current transformers of the same voltage, it has the advantage of oil-free, gas-free, small volume, light and excellent performances.
