Basic Info.

Model NO.:CSM-EKL4
Type:Fault Indicator
Phase:Three

Product Description

Summarize:
The fault indicator of series CSM-EKL was combined with short-circuit fault sensor, display equipment and transmission cable / cable and ground fault sensor, series CSM-EKL was designed for the automatic monitoring of the power grid system, which Mainly applicable to 10KV and below high-voltage switchgear and distribution network systems. For detecting, directing, passing the fault signal. When the cable line failure, it can promptly determine fault orientation, contribute to the rapid restoration of electricity.
Features:
1.Strong anti-jamming capability
Sensors and detection object is always in the potential state,no electromagnetic field interference,does not exist the problem of dielectric breakdown. Optocoupler isolation optical fiber or cable transmissionso the detection signal is securityaccuracy, reliability, stability. Strong ability to adapt to the temperaturehumidity and salt spray corrosion environment
2.Micro-control chip
Due to failure is Sporadic normal micro-controller chip and related circuit stay in saving state; Once the interface fault signal occurs immediately wake micro-controller chip and related circuit upwhich starts the setup program and starts timing the LED at a certain frequency and duty cyclewhile the relay action and remote alarm;Until to the reset time or press the reset buttonthe LED stops workingthe relay resetthe micro-controller chip and related circuit into hibernation again.
3.The sensor is a passive
Direct online detection signal, the use of the electromagnetic field generated by the fault current changes, resulting in the pulse signal excitation circuit, does not affect the normal work of the grid.
4. Fully sealed design
The display instrument design in waterproof circle (including front and rear panels and battery cover are equipped with waterproof ring), free from damp and dust environment restrictions.
5.Lithium battery-powered
No external power supply, direct supply of high-capacity lithium battery (3.6V), quality is stable and reliable power supply, a lithium battery life of up to 10 years or more.

Technical parameters
1,
A wider range of short circuit action and ground action current (according to user needs)
Short circuit current detecting range:800A
Earth current detection range:50-100-150A can be set
2
,The wider fault reset delay time, to provide sufficient time to failure maintenance inspection

Fault reset delay time:7sec-4h-8h-24h
Minimum continuous flashing time: 40ms
3. Work environment

-40° C+70° C
4.Relative humidity
95%
5.Low battery alarm function
When the battery voltage is lower than 2.7V, low battery alarm indicator lights, and prompts the user to replace the battery in time , to prevent the battery is discharged and is not working properly
6.Power Supply

3.6V lithium battery,2400mA/H  Static power: 0.01mA
Maximum power consumption of the display status and alarm:≤0.08mA
7.Transmission cable
3m (according to user needs)
8.Remote transmitting port
Set for the distribution network automation.
