Main Function
1. Short circuit fault alarm indication: Short-circuit fault sensor installed on single phase cable, monitoring the current changes of the power supply line in time, when the current change value reach or exceed short circuit current action when the alarm set point (this value can be setting according to user requirements before producing),the short circuit fault sensor emit alarm signal, the signal through optical fiber sent to the indicator host, the corresponding fault indicator light flashing, Send out alarm indicator. 2. Earthing fault alarm indication: Earth fault sensors installed on the bifurcation unshielded part of three-phase cable, detection of three-phase cable of zero sequence current value, when its value reach or exceed the earth current action when the alarm set point(this value can be setting according to user requirements on the panel), the earth fault sensor emit alarm signal to the indicator host, the earth fault indicator light flashing, Send out alarm indicator. 3. Battery low battery alarm indication: When the indicator host internal battery voltage drops to 2.5 V, generate alarm signal,to mention maintenance personnel change the battery, the alarm signal lasts about two months. Furthermore it equipped with an external power supply interface, it’s can use an external power source by AC/DC5V-10V. 4. Remote alarm and reset: After the short circuit or earth fault occurred, indicator sends the corresponding alarm signal at same time, cooperate with the distribution network automation (FTU) devices, and fault alarm signal can be transmitted to remote monitoring center, can also do remote manual reset operation. 5. Automatic reset: When the indicator emit alarm signals, In a set of automatic reset time, without manual reset, the indicator can be automatically reset. 6. Test and Reset: When the indicator emit alarm signals, press the indicator host "reset/test" button on the panel, can clear alarm status. In the normal state, hold down the indicator host "reset/test" button on the panel for 3 seconds, Panel on all the lights flashing 10 times, also have relais working sound, this means the indicator is in normal working. |
