Split-core Three-phase Flexible Rogowski Coil
Product Description
Product Overview
The coil has excellent transient response ability, no hysteresis and magnetic and saturation phenomenon, wide measurement range, high precision and wide frequency response range. The split-core structure, flexible silicone rubber quilt and skeleton, can be used to measure the current of conductors with large size or irregular shape. The coil requires very little installation space, light weight, simple and convenient installation, and no need to damage the conductor. It is widely used in the measurement of large currents where the traditional CT measuring current cannot be used normally.
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.
* Flexible structure design, can detect the current of irregular primary conductor.
* Low output voltage, high linearity, wide frequency range, no saturation (without integrator).
* The secondary output adopts RJ45 crystal terminal network cable, and the length can be customized according to customer requirements.
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).
