BNWKLC-R Series Open/Close穿刺型Flexible Rosco Coils, primarily used for voltage extraction from needle electrodes for high current measurement protection. The output signal is the derivative of current with respect to time, which can be truly restored to the measured current through an integrator. The coil features excellent transient response, no hysteresis, magnetic, or saturation phenomena, wide measurement range, high accuracy, and a broad frequency response range. The open/close structure, with a flexible silicone rubber sheath and frame, is suitable for measuring current of very large or irregularly shaped conductors. The coil requires minimal installation space, is lightweight, and is easy to install without damaging the conductor. Widely used in high current measurements where conventional current transformers (CTs) cannot be used effectively.
Product Features:
Hinged structure for easy on-site installation and convenient operation. Can be quickly and easily mounted or removed without disconnecting the primary cable under test, effectively facilitating safe and simple current testing.
Flexible structural design for detecting current in irregular single conductors.
Low output voltage, high linearity, wide frequency range, no saturation (without integrator).
Secondary output uses shielded wire, available for custom lengths as per customer requirements.
Application Scope:
Measuring high AC current signals (e.g., short-circuit current); measuring pulse signals with high peaks (e.g., lightning current); harmonic current signal analysis; current measurement for welding machines (e.g., resistance welding); measuring irregular conductor currents (e.g., rail current measurement); instrument measurement, clamp-on transformers (e.g., measuring irregularly shaped conductors).

Installation Precautions:
Transformer operation with power on requires wearing insulating gloves, and hands must not touch the red core of the shielded wire directly.
Do not use if the output leads are damaged. We are not responsible for any safety issues caused by improper operation.
