High Voltage Protection Sensors Long Life Sensor Current Sensor Voltage Sensor

Scope of use and application:

Zero sequence, phase sequence integration of electronic voltage sensor is a new type of high-voltage zero sequence protection sensor, the main application for the inflatable ring network cabinet. The sensor is powerful, small signal output without secondary PT conversion, can be directly through the A/D conversion access to the secondary equipment, in line with the "substation automation system" "digital, intelligent, network" development needs.

voltage sensor can be customised

Main features:

1、Directly output small voltage signal, simplify the system structure, reduce the source of error;

2, does not contain iron core (or contains light load small iron core), will not be saturated, wide frequency response range, large measurement range, good linearity, in the system fault state can make the protection device reliable action;

3, the voltage output terminal secondary short-circuit will not produce overcurrent, and will not produce ferromagnetic resonance, eradicating the power system operation in the major fault hidden danger, to protect the safety of personnel and equipment;

4、Multi-functional, small size, light weight, low energy consumption, reducing ferromagnetic pollution;

5、According to the user's needs, it can directly output zero sequence voltage, or output phase sequence voltage, and synthesize zero sequence voltage through the control device.
