TYPE : Flicker type SNV308.2Â Â
SUMMARY
SNV308.2 series overhead type Fault Indicator system is based on the Sensor that through CT get the (6KV-50KV) n>’s current an>, through smart computer chip(IC) by program calculating, Analysis ,judge the short circuit or ground fault. When Sensor detect the fault happen, then the Fault indicator warn the manager through Flashing one big ultra red led and one ultra green led. It is good for power managing user to find the fault happen reason and place, then fast solve the problem and make the power restore.
*SNV308.2 Fault Indicator with the aid of the remote control PDA(SNV306.2), User can read, reset the indicator’s setting parameter, and can read the on time current etc
 
Â
DESCRIPTION
SNV series indicators suitable for overhead pan>network under a 50KV, for remotes short circuit &Earth fault indicator, through measuring the current of a conductor cable, to judge the fault on the power ording to the change of current, grounding fault, and the fault state, real time current, battery voltage and other information. is uploaded to the remote server, which provides reliable data for the various types of fault diagnosis and location of overhead an>
Production Character:

l Short circuit current impact test, 16KA, 2 second
l Insulator Test:   1) Insulator resistance test　≥10 MΩ   2) Dielectric strength test, 1min,AC 2KV.
l IP protection level test, IP67:  Anti –dust IP6X  Anti-water: IPX7
l Spring clip strong: 8 times self-weight.
l fire-protection rating: 5 grade
Function charactera. real time measurement of three-se on ent；
b. Detection and judgment of short circuit fault；
a) support the judgment of the threshold fault current, short circuit fault；
b) supports Judgment of mutated incremental currents delta for short-circuit faults；
c)Â support for reclosing identificationï¼›
Â
c. Data Upload function；
a)Â periodically upload real-time onent, zero sequence current, and battery voltageï¼›
b)Â Upload the fault status, the fault elimination status and the fault current value in real timeï¼›
d. Parameter setting
a)Â Available to change the parameter setting through computer by factory.
b)Â Available to change and set the parameter though Remote control PDAï¼›
e. Support communication through remote control PDA;
a)Â Available reading and change setting parameterï¼›
b)Â PDA can read Indicator sensor state , Real time ent, battery voltage data.
c) PDA can simulate the ont test through setting Indicator’s parameter.
f. 3 colors to indicate different state.(red, green, yellow)
g. Support ower charge for battery；
h. Support timing reset, power on auto reset, remote reset；
i. can be efficiently mounted and unloaded；
j. The structure parts are made of antirust and anticorrosion material；
k. In waking up state(ng model),During 7 minutes, without operate, there will be auto reset.(Tips: in waking up state, FI prohibited fault test)
The fault indicator type flicker SNV308.2 has an ultra-bright, 360°red LED and a green LED pointing to the bottom for fault indication. Additionally it ha a yellow LED pointing to the bottom to tional status.
1) Red LED:  when permanent fault happen , the red LED will flash,  1 flash very 1 second.
2) Green LED:  when Fault is temporary fault happen. The red LED will flash, at same time, additional green h every 1 second.   ( Temporary fault character :  when fault happen, and power off, but re-closer close successful, and power on again).
3)Â Yellow LED:
Yellow LED ating state of the fault indicator. Operating states are:
__yellow LED does not blink, Â means fault indicator is on service state
__yellow LED blinks every second, means fault indicator is in radio mode
__yellow LED blinks every 3rd second, meanings the battery is running low
