KE6323 Three Phase Isolation Current Transformer

The KE6323 Three Phase Isolation Current Transformer is used on multi-position test benches for testing three-phase meters with closed links between the current and voltage measuring circuits (I-P link).

 

While testing meters with fix closed I-P links, unwanted connections between voltage and current path at each test position will cause significant accuracy reduction.

In this case transformers in the current circuit are required to decouple the voltage from the current path.

 

To achieve complete decoupling the test installation must be fitted with one current transformer per phase for each test position. In this way each meter under test is supplied with isolated test currents via these toroidal-core current transformers.

 

Normally the current ratio is 1:1 and a phase error over the required current range small enough not to introduce significant additional errors.

 

Highlight

1.Standalone through-hole design and small size makes it easy to install and flexible to use.

2. Low power consumption, max. 25 VA.

3. Protection against open circuit and overload

4.Programmable load by-pass

5.Automatic/manual unused position by-pass
