High Voltage Murrayloop

Features:

• Portable, Battery operated.
• For pre-location of low & high resistance constant leakage fault. When used with suitable high voltage DC supply.
• Suitable for constant leakage fault up to 5 K.V. DC.
• Gives reading in % of cable length.
• Accuracy up to 1% of fault distance.
• Null deflection by means of LED.
• Calibrated ten turn potentiometer.

Description:

TII developed T-5101 High voltage murray loop employing solid state technologies to give very accurate % distance to the following faults.

   1. Earth Fault
   2. High resistive cable faults (shunts) (constant leakage).

TII developed T-5101 High voltage murray loop employing solid state technologies to give very accurate % distance to the following faults.

T-5101 is a portable, battery-powered instrument. The above mentioned faults which can not be detected by pulse refection method.

T-5101 operates on the principle of Murray loop & can be used with bride supply D.C. voltage up to 5K.V.

T-5101 measure the distance of the fault from the point of operation to the point of fault of the total length of cable, via calibrated dial and indicates in%.

T-5101 is not suitable for pre-location of low/high resistance flash over or intermittent faults.

T-510 Refectometer with T-1020 or T-1028 or T-1032 surge generators is suitable for high resistance or intermittent faults.

Note: For flashing faults Murray Loop is not suitable. Use Reflectometer T-510 for such faults.
