3.1 Fault indicate function

The lights on the L1,L2,L3,and Earth buttons will flash with a an interval of 4 seconds,if the short circuit fault or earth fault occur.This can be reset automatically according to the time delay set before delivery from the factory or manually reset by pressing button of “Reset/Test”.the status of low battery capacity of the indicator can be uploaded by wireless,in the meantime, The indicator will flash for low battery voltage(with 4 seconds of interval).

3.2 Reset/Test function

 

3.2.1 Reset: press lightly the “Reset/Test” button slightly, it will reset after all lights on in indicator

3.2.2 Self-checking:

press ““Reset/Test” button, press on L1 and L2 in turn, then let go, after all lights are on at mean time once, the corresponding address lights is on. In 10s, corresponding address lights are on again, then self-checking finished.(indicator current address refer to label number in the back).address is corresponding to L1,L2,L3,E lights by BCD code, instructions is as following table:

Address black point means the corresponding LED is on
L1(1) L2(2) L3(4) E(8)

3.2.3 L1,L2,Wireless function self-checking

press “Reset/Test” button, press on L1 and L2 and L3 in turn, then let go, the indicator will send wireless status message to upper computer, the “ battery low voltage” light will flash fast 3 times to indicate, it tells test finished. If transmission is failed, the test status will exit automatically in 1 minute. Operator also can press slightly on “Reset/Test” button to reset indicator and exit this status.

3.2.4 indicator address configure

When install the indicator, the panel indicator address should not be the same in the same RMU or switching station, if the address is same, it will result in the information transmission mixed error.each indicator labels its current address(when installed, its address also can be checked by the way of self-checking. If need to modify indicator address,please follow the following steps:press “Reset/Test” button, press on L1 and L2,L3,Earth fault lights in turn, then let go,light of “low battery voltage” flash(with an interval of 1s) and change to ready- setting state(automatically exit in 20s), press again“Reset/Test” button, lights of L1,L2,L3,Earth fault will display address (1-8)by the address sequence of BCD code, when it displays the address which requires to be configured, then let go at once,the expected address will flashing clockwise with the light of “low battery voltage”, at this time, press the button again and save this address. The operator can refer to the self-checking steps mentioned in 2.2 to check if the address written is right; if configuration is not right or cancel this configuration, please not save, the configuration status will exit automatically in 20s.

cable short circuit fault indicator

2. Working principle

 

Using clip-on line structure of fault detector as sensor of measuring load current. The intelligent controller control as the core with little power consumption ,When a circuit has a short circuit fault,The fault detector automatically recognize fault current characteristics to judge intelligently. In the meantime. the action signal will be transmitted to the panel indicator installed locally by fiber and locally indicating,then the panel indicator send the wireless signal to DTU to realize the remote transmission of fault signal

3,Installing methods

 

Clip the indicator on the line as shown in the pictures1.2.3, rotate the screws clockwise to fix it and tighten the fault detector, connect the fault detector and panel indicator through short-distance plastics optical fiber; make sure to insert the optical fiber to the other end and tighten the nut. The length of the optical fiber should be less than 10m,The shorter the distance ,the higher the reliability .optical fiber cross-section is cut flat with a paper cutter, which is beneficial to the transmission of fiber signal

After the test completely cover the rubber cover,in order to avoid abnormal indicator accused by long-term light leakage

                              earthed fault detector

working principle

Using specially designed open zero-sequence CT as sensor of measuring zero-sequence current, micro-power consumption intelligent controlling chip is as core. When earth fault happen, earthed detector will automatically distinguish fault current characteristics to judge earth fault intelligently, then transmit the data to panel indicator to display by optical fiber, and the panel indicator will send wireless signal to DTU to realize the remote transmitting for fault signal.

4. functions and characteristics

4.1 Install and uninstall simply.adaptable to detect zero-sequence current in three-phase cable with outer diameter below 110mm.

 

4.2 Epoxy resin casting,adaptable to run outside in a long term

4.3 detect earthed fault

  • Used for low resistance grounding system:zero-sequence current starting value adjusted range is 10-200A before delivery,default value is 30A;delay time range can be adjusted as 50mS~60S before delivery, default value is 200ms.when zero-sequence current is above current starting value and lasting time is above delay setting time then it can be judged as fault. The parameters can’t be changed at site, need to clarify when make order.
  • Used for low current earthed system: detect special signal and meet fault judgement condition then judged as earthed fault.
