earth leakage indicator

,

fault locator

This kind of device is applied to the overhead power distribution network automatic system from 6KV to 35KV,is used to improve the safe and reliable operating performance through centralized monitoring the current, temperature and fault condition on the power distribution circuit.

system Constructure:

Power Distribution Network Earth Fault Indicator Over 90 / 100 Alarming Accuracy 0

Main features:

GSM or GPRS forwarding;

GSM (short messages) and GPRS (data) are mutually the standby mode, which are used to send the substation condition, circuit load current, indicator status and fault information to main distribution network station, to ensure the reliable transmitting of distribution network fault information.

Remote upgrade;

The equipment program can be upgraded conveniently through master remote maintenance station.

Work mode setting;

The terminal can be in the two-remote or one-remote working mode by setting the intrinsic parameters of remote terminal uint.

Two-remote working mode: the terminal is online in real time, and the circuit load current and circuit status can be uploaded.

One-remote working mode: the terminal is online regularly; when the circuit breaks down, the terminal opens GPRS module power supply and sends the fault information to main distribution network station.

Functions:

1)Wireless receiving: the fault point information and load current information sent by indicator are received via short-range wireless network mode.

2)GSM or GPRS forwarding: GSM (short messages) and GPRS (data) are mutually the standby mode, which are used to send the substation condition, circuit load current, indicator status and fault information to main distribution network station, to ensure the reliable transmitting of distribution network fault information.

 3)Solar power supply: the solar power supply mode is applied, and the maintenance-free 8AH lead-acid battery or 12AH lithium iron phosphate battery is provided, with the working temperature range of both batteries of -35℃~75 ℃ and -20℃~75℃ separately.

4)Optional communication protocol: IEC870-5-101 protocol or 104 can be selected for the connection with the third party equipment to upload the fault and shift information.

5)Remote upgrade: the equipment program can be upgraded conveniently through master remote maintenance station.

6)Convenient maintenance: the parameter setting and equipment maintenance can be performed conveniently via wireless setting terminal.

7)Event recording: the device can record the maximum 500 pieces of SOE events, providing the rich data support for system fault analysis.
