Split-type Flexible Rogowski Coil Without Integrator

A Rogowski Coil is a specialized electrical transducer designed to measure alternating current (AC) with high accuracy, wide bandwidth, and excellent linearity. It operates on Faraday’s law of electromagnetic induction, which states that a changing magnetic field induces a voltage in a coil. The Rogowski Coil consists of a helical winding placed around the conductor carrying the current to be measured. Because it has no magnetic core and is air-cored, it produces a voltage signal proportional to the rate of change of current (di/dt). When this signal is integrated electronically, it yields an output directly proportional to the actual current.

Product Features

*  Split-core structure, easy to install on site and easy to operate. Quick and easy installation or removal without disconnecting the primary cable under test, effective for safe and easy current testing.

*  Low output voltage, high linearity, wide frequency range, no saturation (without integrator).

*  The secondary output adopts shielded wire, and the length can be customized according to customer requirements. 

*  Flexible structure design, can detect the current of irregular primary conductor.


Product Application

Measurement of high current AC signals (such as short-circuit current); measurement of pulse signals with high peak values (such as lightning current); analysis of harmonic current signals; current measurement of electric welding machines (such as resistance welding); measurement of irregular conductor currents (eg: rail current measurement);instrument measurement, clamp meter transformers (eg: measuring conductors with irregular dimensions).
