Protection Class CT for Reliable Power System Safety

Protection & PS Class Current Transformer

Safety and a continuous operation of electrical circuits is essential in a modern electrical system. Protection Class Current Transformers (CTs) are essential to protect electrical networks to measure current accurately and provide support to protective relays. In Powertrac India, we offer high-end line of Protection Class CTs, which are tailored to provide accuracy, longevity and reliability operation in both industrial and commercial markets.

What is a Protection Class CT?

Protection Class CT is specially designed to operate with protective relays. These transformers are designed to be accurate even in fault conditions like short circuiting, surges of current, etc, unlike normal metering CTs. These CTs are primarily designed to sense current levels that are not normal and activate protective measures that cut power to downstream circuits to avoid damage to equipment and provide safety.
Protection and PS Class Current Transformer: Our solutions to Protection and PS Class Current Transformers are accurate and highly built and they are well suitable to be used in critical protection systems.
