6KV-110KV epoxy resin insulated communicable fault passage indicator for overhead line
The fault indicator for overhead distribution lines is used indicating of phase-to-phase and phase-to-earth faults by determining short circuit, over-current and power features to detect faults and provide a local light indication. In addition, the indicator also has current measurement and wireless data communication capabilities, by sending the fault signal to FTU,in order to comply the function of the remote communication and the remote monitoring, to help operators to find the point of failure quickly and shorten the outage time and improve reliability.
The fault indicator installed on the overhead lines, which clipped on each phase so that to detect current and Voltage signal in this phase using itself clipped line structure. Through the low-power chip, it completes current calculation, short circuit, ground fault detection, and through built-in low-power RF modules achieves short distance wireless communication.
After the indicator is installed, the line current has been measured . When the current meet the characteristics of the fault, the indicator immediately sends the fault current and the fault information to the nearest terminal device by the RF, while triggering a flop and flash indication.
The lineman simple follows the flashing fault indicators all the way to the first non-flashing fault indicator, thereby identify the fault location.
The terminal device receives the fault information can further upload, so master station can get useful information and determine the fault zone according to the sub-station uploaded information.
Shocks and vibrations:
a)Power frequency magnetic field test
b)Grip test
Order Note:
The fault indicator is installed on the load side, and the phase number A1, B1, and C1 are installed on the main line, and the A2, B2 and C2 are installed on the branch line.
