Description
The FICO FNCT-01 is a specialized outdoor current transformer designed specifically for neutral grounding applications in power distribution networks. Unlike standard indoor CTs, the FNCT-01 is engineered with a rugged, weather-resistant epoxy or porcelain-equivalent resin body to withstand harsh environmental conditions, including UV exposure, rain, and temperature fluctuations. It plays a critical role in detecting earth faults and monitoring neutral current flow to ensure the safety of transformers and substations.
Key Features & Technical Specifications
