Features 

Short circuit and earth fault indicator Xtester-EKL4.2/485, with 485 port have signal remote transmission function. Its in the digestion absorption based on similar advanced products at home and abroad, for urban and rural power grid ring network distribution system design of a special automatic monitoring device. In a ring network power distribution system, especially in the extensive use of ring net load switch (Ring Main Unit) system, if happened to the next level in the distribution network system short circuit or earth fault, at the next higher level power supply system must be specified in between the breaker, in order to prevent major accidents. In the breaker protection, belonging to the level of network system all the power. Through the use of this product, can rapidly and accurately indicate the faulty parts, greatly save the lookup part of the time, reduce the outage time and power scope, improve power supply reliability.

Working Principle

When the power supply circuit has a short circuit or earth fault occurs, the short circuit current or earth fault current make electromagnetic field changes, fixed in cable sensors on the measuring coil produce pulse signal, when the value of the pulse signal reach or more than the set of fault current value, fault indicator automatically memory fault state, fault indicator lights flashing issued instructions, at the same time by long range alarm interface, and the fault signal transmitted to the monitoring center, the staff through fault indicator signal can promptly and accurately to line fault location, timely troubleshooting, restore power supply.
