LZCK-55 GFUVE split core current transformer & IP65 outdoor split core ct 5A for a distribution transformer
The split core transformer measures current in a 5 A or 1 A secondary CT circuit and works in conjunction with the NR disturbance fault recorder to monitor secondary currents. It is designed to clamp around the secondary circuit wires from the primary CT and is intended to connect an in-line CT for situations which do not allow an “open-circuit”.
LZCK-55 ip65 outdoor current transformers are applicable for AC power system 35kV and measurement of current of power supply equipment below 10KV also can be used for microcomputer protection. This type of current transformer employs imported silicon steel which with high permeability as magnetic material, has the characteristics of Small magnetic circuit loss and can be split, its semicircular core and secondary windings employ high quality epoxy resin vacuum, casting in plastic-case (ABS&PC) which is flame retardance anti-moisture, stable performance, no maintenance.
Split-Core Current Transformers GFUVE® maintains a large in-stock inventory of Split-Core Current Transformers, including Metering Class, Multi-Ratio, Relay Class and Rogowski Coils for most common applications. Below is a list of all split-core current transformers available through GFUVE, however, not all models are in-stock.
