bushing type current transformer

LR (B) series bushing current transformers are suitable for oil immersed transformers or high-voltage circuit breakers of 35kV and above. Can be used for current measurement, measurement, relay protection, zero sequence current protection, etc.

When used for oil immersed transformers, it is often installed in the transformer riser, with the primary part being the high-voltage bushing and the secondary part being led out to the terminal block. It must be used in conjunction with the casing. When used for high-voltage circuit breakers, it is often installed inside the casing, with multiple sets of current transformers distributed on both sides of the switch. The primary part is the high-voltage bushing, and the secondary part is led out to the CT junction box.
