Bushing Shaped Capacitive Voltage Divider Through The Wall Plug-In Electronic Voltage Sensor

Bushing-shaped electronic voltage sensor through-the-wall plug-in electronic voltage sensor

The bushing-shaped electronic type zero-phase integrated electronic voltage sensor is a new type of voltage sensor for phase-sequence and zero-sequence voltage protection. This electronic-type voltage sensor adopts advanced capacitive voltage-dividing technology, which can accurately collect zero-sequence voltage signals. The electronic voltage sensor is matched well with the breaker of an outdoor pole-mounted high-voltage vacuum breaker and switchgear, and it is widely used in various power distribution systems.

Features

• It detects voltage of zero-sequence and phase-sequence with high precision, and has stable and reliable operation;
• It adopts the principle of capacitive voltage divider and the technique of liquid-independent encapsulation;
• It consists of three-phase independent sensors with high-voltage cables and can be directly connected to the high-voltage conductor of the main switch.

​Technical Parameter

Application

It is used in ring main unit, for accurate measurement, control and protection of LV, MV and HV electrical power systems by dividing input high voltage 10kv/√3 into output voltage 3.25V/√3 for phase sequence and 6.5 V /√3 for zero sequence as signal voltage, which is for background detection.
