SMR-CTB Current Transformer Secondary Overvoltage Protector
- Description
-
1. Product Introduction
Current transformers (CT) are widely used in power systems for primary measurement and control. Under normal operation, the secondary side of the transformer is in an approximately short-circuited state, and the output voltage is very low. If the secondary winding is open-circuited during operation, or if the primary winding carries abnormal currents (such as lightning currents, resonant overcurrents, capacitor charging currents, inductive starting currents, etc.), it can generate overvoltages of several thousand volts or even tens of thousands of volts on the secondary side. This not only poses a risk to the insulation of the secondary system but can also cause the transformer to become overly excited and burn out, potentially endangering the safety of personnel. Using a CT secondary overvoltage protector can effectively prevent accidents caused by the open circuit of the current transformer secondary.
