Split-core Punture&Power Harverster Flexible Rogowski Coil

TRKLC-R series flexible Rogowski coils with split-core puncture and electricity extraction are mainly used for puncture needle voltage extraction and high-current measurement protection.
Availability:

The output signal is the differential of the current against time, and through an integrator, the measured current can be truly restored. 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 cover 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 shielded wire, and the length can be customized according to customer requirements.


Scope of 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).

Output lead description:

1. The input end is a cable through the core (P1 → P2);

2. The output end is led out by a three core shielded wire;

3. Red represents the voltage measurement terminal;

4. Blue and yellow are secondary voltage signal outputs;

5. Define the polarity correspondence between "P1" and the blue line as the end with the same name (*).


Installation Precautions

When the transformer is powered on, you must wear insulating gloves, and your hands must not directly touch the red core of the shielded wire;

Do not use if the output leads are damaged. Our company is not responsible for any safety problems caused by improper operation.
