Description

SNV-308 Overhead type earthing and short circuit fault indicator (four remote type)
SNV-308 is suitable for overhead line 35KV and below a four remote function grounding and short-circuit fault indicator. SNV-308 through real-time measurement and according to the current cable current waveform changes to determine the short-circuit fault on the power lines and 
grounding fault, and the fault state, real time current (fault current), battery voltage, temperature, electric field of cable and other information uploaded to the remote server, which provides reliable data for the various types of fault diagnosis and location overhead line. SNV- 308 by handheld PDA in the process of using (SNV- 307) or communication terminal (SNV- 309) for its flexible configuration to meet the needs of different environment monitoring overhead. 

Function:

■ Telemetry and telemetry 
■ Intelligent motor control card 
■ Can be charged to install and remove 
■ 6 LED fault status indicator light 
■ 1 LED running status indicator light 
■ Intelligent judgment of grounding and 
short circuit fault 
■ Support hand held PDA (SNV- 307)
■ The flop position of a self-test per hour 
■ Battery voltage is sampled once per 5min 
■ Support online CT pickup power and solar power 
■ To support the avoidance of various non fault cases 
■ Support timing reset, power on reset automatically, 
remote reset 
■ Support recording function

Characteristic:
■ Support for the judgment of the 
coincidence gate 
■ Accurate synthesis of zero sequence 
current 
■ Intelligent motor control card 
■ Ultra low power consumption in real time 
sampling 
■ A wave of 64 point difference sampling 
■ Support remote signal, telemetry, remote 
control and remote control. 
■ Can accurately identify the 20mS minimum 
fault time 
■ Support remote server upgrade and 
parameter settings 
■ Accurate judgement of the grounding fault 
by the change of zero sequence current 
■ Time synchronization between the sensor and the 
sensor 
■ Optional threshold, incremental, percentage of 
multiple fault judgment 
■ Calibration of each sensor is carried out to ensure 
consistency of sampling. 
■ The accuracy of the current sampling is less than 
10A ±0.3A,10- 2000A ±2%
■ Temperature sampling precision ±0.5℃, Voltage 
precision of ground electric field±10%
■ Can accurately determine the temporary fault, 
transient fault, permanent fault, grounding fault 
■ A current greater than or equal to 5A, no external 
power supply 
■ Solar electric, CT electric, a built-in 3.2V lithium 
iron phosphate battery and a main 3.6V lithium 
battery bottom and a super capacitor
