CTs

Current Transformers sense the current flowing in cables and are used with CT operated meters, three CTs are usually required for a 3 phase meter. They are available in a range of types to suit the particular application and include both feed through types and split core models for retrofitting.

Split Core   TP 23 200A to 5000A
 

TP 23 200A to 5000A Current Transformer
Type: Split Core 5A secondary
Aperture: See Datasheet
Class 1-3 See Datasheet

The main features of TP transformers are:
– Small size and easy mounting
– Wide inner window, allowing clamping of large cables or bus bars
– Wide range of sizes to accommodate all the existing installations
– Terminal strip to short circuit the secondary side during the installation
– Primary ranges from 200 to 5000 A
– Secondary output 5A (1A or 1.5 V optional)
– High accuracy and reliability
