Features for communicable indicators
Fault judge: identifying the Short-circuit fault , without testing
the action value
reset way: Timing reset, manual reset , Intelligent automatic reset
(A few minutes after Tripping, once the fault is cleared, reset
itself upon the power return)
Handling charge: installing and removing while line is in charging
condition
Rust and corrosion protection: Structure part is made of
corrosion-resistant material
Surge suppression: to eliminate the wrong phenomenon of closing
inrush current
The feature of the inverse: operating characteristics of maximum
protection with the substation,to improve the action accuracy
Indication: Flashing and triggering a flip
Drop: Products from a height of 1 meter free fall to the concrete
floor, no damage

Main features for Remote transmission units
1. 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.
2. Remote upgrade
The equipment program can be upgraded conveniently through master
remote maintenance station.
3. 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.
4. Functions
4.1. Wireless receiving: the fault point information and load
current information sent by indicator are received via short-range
wireless network mode.
4.2. 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.
4.3. 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.
4.4 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.
4.5. Remote upgrade: the equipment program can be upgraded
conveniently through master remote maintenance station.
4.6. Convenient maintenance: the parameter setting and equipment
maintenance can be performed conveniently via wireless setting
terminal.
4.7. Event recording: the device can record the maximum 500 pieces
of SOE events, providing the rich data support for system fault
analysis.
