• High-Sensitivity Zero-Sequence Current Detection: An yanayi ga ground fault monitoring a cikin power systems, it accurately captures zero-sequence components generated by the vector sum of three-phase currents (often as low as several milliamps). Using high-permeability cores (such as nanocrystalline/permalloy) and special winding designs, it maintains linear response within the 0.1A~100A zero-sequence current range, ensuring reliable early warning of ground faults.

• Anti-EMI Structural Design: The core adopts magnetic shielding technology, and windings are wrapped with double-layer shielding to effectively suppress power grid harmonics (3rd, 5th harmonics) and external electromagnetic interference (e.g., lightning, switching operation pulses). Passing IEC 61000-4 EMC tests, it maintains measurement accuracy ≤1% in complex electromagnetic environments.

• Wide Frequency Response Characteristics: With a frequency response range of 10Hz~100kHz, it accurately detects 50/60Hz power-frequency zero-sequence currents and captures high-frequency ground transient signals (such as arc grounding overvoltage harmonics). Suitable for various system grounding modes, including ungrounded neutral and arc suppression coil grounding.

• Fully Enclosed Insulation and Protection Design: Adopting epoxy resin vacuum casting fully sealed structure with IP65 protection rating, it resists moisture, salt fog, and dust. Suitable for harsh environments like outdoor cable trenches and humid basements, its maintenance-free design reduces O&M costs.
