MEWOI-JYZ-HW  Overhead live line fault indicator, fault passage indicator(FPI),Permanent Fault,Transient Fault,Earth Fault

Introduction


         MEWOI-JYZ-HW Overhead Line Fault Indicator is usually used in 5~38KV (can be customized by 44KV, 69KV and 110KV ) overhead line power distribution network to monitor and detect short-circuit and earth fault. The fault signal is indicated by three ultra-bright blinking LEDs with 360º sight.

         The indicator can be mounted under live conditions with the help of an adapter and a hot stick. The parameters such as trip current, reset time,blinking interval, etc., can be read and adjusted by a bidirectional wireless tool. Permanent fault, transient fault and battery low voltage alarm can be distinguished and indicated separately by 3 different ultra-bright blinking LEDs. And the earth-fault can be indicated by two alternating different ultra-bright blinking LEDs.

Main Features


Permanent Fault:  Red ultra-bright blinking LED.

Transient Fault:  Green ultra-bright blinkingLED.

Earth-fault: Red and Green ultra-bright LEDs blinking alternately.

Low Battery Warning: Yellow ultra-bright blinking LED

Parameter Adjust: The parameters can be read and adjusted by bidirectional wireless tool.

Power Supply: The indicator can take power from overhead lines, with lithium battery as backup.
