Overview: WHLEKL series circuit fault indicator is installed in the distribution network supporting the ring network, cable branch box, inflatable cabinet, high and low voltage equipment, counters in the home, on the box changes to indicate the corresponding cable segments short-circuit and ground fault of a real-time monitoring devices. In order to solve this indicator provides the best way to find fault! When a line failure, short circuit or ground sensor will signal to the host through a fiber optic receiver, the host receives the signal panel indicator lights red flashing alarm, manual inspection glows green when the host flashes nine times. To provide a convenient inspection personnel, to improve work efficiency, reduce outage time, the rapid restoration of electricity and improve reliability and economic benefits. Reset time can be set. Design: short circuit and ground fault indicator consists of the following components: a host: three short-circuit fault sensors: a ground fault sensor: three short sensors, a ground sensor, and the host, the connection wires are: red, green, yellow, Black, 4 plastic optical fiber. Reading instrument mounted in a plastic box with a meter reading time reset circuit and ground fault circuit assignment consists of a flashing LED indicator, each cable consists of a short-circuit fault on the flashing LED light means reading instrument with testing, Each sensor consists of a reset button plastic housing and short circuit and ground fault detection caused by pulse current coil. Different versions of the sensor connecting wires or fixed on the sensor, or by an optical fiber sensor plug, the shell and meet IP injection molding conditions of use. The main technical parameters: short-circuit current, ground current can be set. Factory first set short-circuit fault current operating current: 800A-1000A ground fault trip current: 20A-50A Accuracy: ± 10% Ambient temperature: -25 ~ +70 ℃ Humidity: +40 ℃ Relative humidity ≤ 95% Power: Standby ≤ 0.01mA; instruct ≤ 0.5mA power supply: Lithium battery 3.6V/2.25Ah Auto Reset Time: 7Sec-2h-4h-8h can set other settings can be booked output relay contact capacity: 230V AC 1A / 125VDC 1A / 30VDC 2A EKL Product features: 1, short circuit alarm indication: Short circuit sensors that detect the supply line current, when its value reaches or exceeds the short-circuit current start the alarm setting value (this value can be based on user requirements factory setting), short-circuit sensor sends message signal Host receives this signal through an optical fiber, an alarm indication signal (LED flash). 2, Ground Alarm Indication: When the ground sensor detects ground circuit current reaches or exceeds ground currents activate the alarm insufficient given value (this value can be based on user requirements factory setting), send an alarm signal to the host through a cable or fiber receives This signal, a corresponding alarm indication signal (LED flash). 3, Low battery alarm indication: When the indicator inside the battery voltage from 3.6V down to 2.7V, an alarm signal to alert maintenance personnel to replace the battery. 4, alarm remote: Depending on the indicator host can drive the corresponding alarm indication signal relay for remote transmission of the signal. 5, the automatic Reset: When the indicator is an alarm, in the setting of time, without manual reset, the indicator can be reset automatically. The main technical parameters: operating current short-circuit fault: 800A ground fault trip current: 20A Accuracy: ± 10% Ambient temperature: -25 ~ +70 ℃ Humidity: +40 ℃ Relative humidity ≤ 95% Power: Standby ≤ 0.01mA; instructions ≤ 0.5mA power supply: Lithium battery 3.6V/2.25Ah Auto Reset Time: 6H 12H 24H can be set, other settings can be booked output relay contact capacity: 230V AC 1A / 125VDC 1A / 30VDC 2A Panel Cutout Dimensions: 92 (mm ) X44 (mm) Guangzhou gifted than the special Power Technology Co., Ltd.
