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