EKL4 type short circuit and ground fault indicatorDetailed product description：

The EKL4 short circuit and ground fault indicator is a device used to detect short circuits and ground faults. In the ring network distribution system, especially in systems that extensively use ring network load switches, if a short circuit fault or grounding fault occurs in the lower level distribution network system, the upper level power supply system must be disconnected within the specified time to prevent major accidents. By using this product, the faulty part can be marked. Maintenance personnel can quickly locate the faulty section based on the alarm signal of this indicator, disconnect the faulty section, and promptly restore power supply to the fault free section, which can save a lot of work time, reduce power outage time and scope.

The following are the improvements or advantages of EKL4 compared to EKL3:
1. Composition of short circuit and ground fault indicator:
Three short-circuit fault sensors
A ground fault sensor
A reading instrument
Four optical cables
The prominent feature of EKL4 short circuit and ground fault indicator is that all connections between sensors and reading instruments are made through optical cables. This is an advantage as the sensor can be directly installed in unshielded cable areas. The result is that shielding may not necessarily pass through the frame, but can independently pass through the steel strip. This method provides common applications for short circuits and ground faults.
2. The adjustment of operating current, reset time, and battery replacement can all be operated directly without opening the box.
