Ground Fault Solid-Core Current Transformer

The AcuCT G Series Ground Fault Solid-Core CT detects leakage current to protect against small ground faults in a power distribution system. It accurately measures current imbalance in circuits which helps identify ground faults, insulation degradation and leakage between ≥ 10 mA ≤ 10 A (100 A). The enclosure design is suitable for indoor and protected outdoor installation under various environmental conditions.

  • Accuracy of 5% between 1 – 120% rated current for ground fault detection
  • Short-Time Thermal Current (STTC) rated at 15 kA for 1 second
  • Surge rated current can withstand 50 kA/50ms
  • Built-in protection and durability with secondary overvoltage suppression
  • Installation ready with solid-core form factor and twisted-pair leads

About AcuCT G Series Models

Current Transformers for Ground Fault Detection

Ground fault current transformers are designed for ground fault and leakage current detection in power distribution systems. With a transformation ratio of 600: 1 and an accuracy of 5%, it provides an mA output proportional to the input range for protection relays. Rated to withstand a short-time thermal current of 15 kA for 1 second and a surge current of 50 kA for 50 ms, it ensures reliable performance under fault conditions.
