overhead line fault detector 6KV-66KV new type, be tested,more accurate red flag or LED flash light CE&Manufacture&ISO9001

LED flash light Overhead line fault locator and fault detector  

Technical Parameters 

HSFI series overhead line short-circuit fault indicators

· Short-circuit Fault Detection: 

   If/I0 is larger than the tuning value of the fault current (The value rang is between 1.0A~60A,can be adjusted automatically), in which I0 is the load current and should greater 3A; If is the fault current and should greater 200A, the line voltage is lower than 3000V.

·  Over Current Fault Detection:    

Automatic setting the line fixed over current (the stepping is 50A), line current> fixed over current and delay tripping( the line current is 0).

· Line Voltage: No limitation

· Line Type: Overhead line(insulated, bare wires)

· Reset:

For transient faults, reset based on the given time(12 hours) by default;

For permanent faults, reset when power is up.

·Alarming:

Red flag and LED flash light

·Power: ≤3μA

·IP Protection Class: IP67

·Temperature: -40°C~+70°C

·Lifetime: Over 10 years

HESI series overhead line earth and short-circuit fault indicators

· Short-circuit Fault Detection:

If/I0 is larger than the tuning value of the fault current (The value rang is between 1.0A~60A,can be adjusted automatically), in which I0 is the load current and should greater 3A; If is the fault current and should greater 200A, the line voltage is lower than 3000V.

· Over Current Fault Detection:    

Automatic setting the line fixed over current (the stepping is 50A), line current> fixed over current and delay tripping( the line current is 0).

· Earth Fault Detection:

The RMS value of sudden changes on the transient current in 3ms Ip is no less than 15A, the line voltage is lower than 3000V for over 15s (the period can be tuned).

· Line Voltage: No limitation

· Line Type: Overhead line(insulated, bare wires)

· Reset:

For transient faults, reset based on the given time(12 hours) by default;

For permanent faults, reset when power is up.

·Alarming:

·Power: ≤3μA

·IP Protection Class: IP67

·Temperature: -40°C~+70°C

·Lifetime: Over 10 years
