Electronic No-Load Voltage 7500V High-Resistance Cable Fault Detection Sheath Fault Pre-Location High-Voltage Bridge
The cable outer sheath fault tester is designed based on the MURRAY bridge principle and can be used to locate the breakdown points of various wires and cables and the defect points that have no breakdown but low insulation resistance values.
The equipment uses an electric voltage regulator and an R-type transformer to form a high-voltage constant current source, and the button operation can increase or decrease the voltage.
The no-load voltage is 7500V, the short-circuit current is 100mA, and a high-sensitivity amplifier and galvanometer are used to indicate balance. It forms a balanced bridge with a proportional potentiometer, and the whole is placed at a high potential.
The measurement cable is a specially designed two-core high-voltage rubber cable. The four-terminal resistance measurement method is used to avoid errors caused by lead resistance.
The entire panel is at low potential. One-touch operation, enter the cable length and automatically calculate the fault distance. The high voltage source and bridge are integrated in a portable protective box. Therefore, the device has high voltage, light weight, easy operation and safe use.
