Description
The FICO FCT-17P PALM is a high-performance, single-core current transformer (CT) specifically designed for medium-voltage indoor applications. Featuring a “Palm” type primary terminal, this transformer is built for high-conductivity connections within 12kV power distribution networks. It is vacuum-cast in high-grade epoxy resin, ensuring superior mechanical strength and reliable electrical insulation even in demanding industrial environments.
Key Features & Technical Specifications
Palm Primary Terminal: Designed with a sturdy, vertical “Palm” connector for secure and efficient bolting to primary busbars or cables.
Optimized for Protection: Rated at Class 5P20, meaning it maintains high accuracy even during fault conditions up to 20 times the rated current, making it ideal for relay protection.
Dielectric Performance: Built for a maximum system voltage (Um) of 12 kV with a certified insulation level of 12/28/75 kV.
Short-Circuit Resilience: Rated for a Short-Time Thermal Current (Ith) of 20 kA for 1 second, providing robust protection against high-energy system faults.
Technical Ratings:
Current Ratio: 400/5A
Rated Output (Burden): 15 VA
Rated Frequency: 50 Hz
Standards Compliance: Fully compliant with IEC 61869-1/2, meeting international benchmarks for instrument transformer quality and performance.
Safety & Maintenance: Includes a transparent, sealable secondary terminal cover to prevent accidental contact and unauthorized tampering.
Durable Construction: The vacuum-cast epoxy resin body is resistant to moisture, dust, and chemical exposure, ensuring a long service life.
Safety Warning: As per international safety protocols, one secondary terminal must be earthed during service. Never leave the secondary winding open-circuited while primary current is flowing to avoid hazardous voltage buildup.
