10kV line distribution network automation fault indicator
Combining micro-power wireless networking technology of our company and advanced algorithm for fault section detection in distribution system at present, this overhead power line fault indicator possess the function of micro-power wireless networking, through which fault. AQ-50 Fault Detection Devices detect even high-impedance earth faults in any type of cable or overhead line distribution network (compensated, isolated, or directly earthed). JYW-60 overhead power line fault indicator, adopts ultralow power consumption wireless MCU, and integrated high performance microprocessor and RF transceiver as well as high resolution ADC (analog-to-digital converter) inside, conforms to Q/GDW 436-2010 standard. Our TE Kries fault indicators provide fast and accurate fault detection for overhead and underground power distribution systems, helping you minimize downtime and improve grid uptime. For overhead lines, our TE Kries IKI-Overhead (IKI-OH) fault current indicators can be easily installed at.

What current rating should be set for relay protection
For example, if your system has a steady current of 5A and an inrush current of 10A, choose a relay rated for at least 12-15A. Current Setting: The adjustment of the relay's pickup current by changing coil turns, expressed as a percentage of the CT's rated secondary current. Example 2: Protection of a Large Pump Motor Scenario: A 75 A motor with a service factor of 1.
