Spark Gap A046

Current Transformer Protector and Measurement

The Spark Gap acts to protect the secondary windings of Measuring or Protection Current Transformers, preventing them from being damaged if the winding is opened incorrectly.

When the open secondary voltage exceeds the value of 3500Vpeak (~2500Veff), the spark gap actuates, protecting the CT.

If the discharge persists, after 5 to 10 seconds, the spark gap will melt and permanently short-circuit the TC. The Spark-Plug must then be replaced with a new spark gap: replacement is simple and quick.

The Spark Gap comes assembled with 5 Spark plugs, allowing the protection of 5 Current Transformers.
