Iron Cores Series
The series of current transformer is suitable for indoor use. Rated frequency 50Hz or 60Hz, used for three-phase cable grounding protection in rated voltage 35kV and below low grounding current system. It can also be used with relays.
During installation, the current transformer can be divided into two parts, and then merged into one, and held tightly with a hoop. It can be installed without power off.
The primary insulation of the current transformer is guaranteed by the cable. The insulation performance of the secondary winding is only tested. The voltage resistance of the secondary winding to the ground is 3KV per minute.
The iron core is ring-shaped and cast in resin. The secondary winding wounds round the core the diameter of internal hole of the core is 80/100/120/160/180/200/240/300mm, which is used for cables to cross through.
