Product Description
Product Description
Introduction The cable outer sheath fault tester XHHG521A 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.
This device uses an electric voltage regulator and an R - type transformer to form a high - voltage constant current source. The voltage can be increased or decreased by button operation. It has a no - load voltage of 7,500V and a short - circuit current of 100mA. A high - sensitivity amplifier and galvanometer are used to indicate balance. Along with a proportional potentiometer, it forms a balanced bridge, and the whole is placed at a high potential. The measurement cable is a specially designed two - core high - voltage rubber cable. To prevent errors caused by lead resistance, the four - terminal resistance measurement method is used. The entire panel is kept at a low potential. One - touch operation enables users to enter the cable length and automatically calculate the fault distance. The high - voltage source and bridge are housed in a portable protective box. Hence, the device offers high voltage, light weight, easy operation and safe use.
High voltage bridges are particularly suitable for 1. The high-resistance breakdown point of the cable after laying, especially the linear high-resistance breakdown point that is difficult to burn into low resistance, such as the linear high-resistance breakdown of the cable intermediate joint. 2. Flashover type breakdown point. After breakdown, the constant current source can maintain the arc, a stable current flows through the bridge, and the bridge has sufficient sensitivity. 3. Defects that have not yet broken down but have low resistance, such as insulation defects found with a megohmmeter that have low cable resistance but do not break down under the operating voltage.
Product Features
Output voltage is adjustable;
Has high accuracy and stability;
Adopt high-sensitivity amplifier and galvanometer to indicate balance;
Zero protection;
Automatically test fault points, but retain manual testing functions;
Compared with the wave reflection method, the bridge balance method has no blind area and is used to determine the breakdown point of short cables and near the ends.
Product Parameters
No load voltage
≥7500V
Short circuit current
≥100mA (when adjusting balance, it is recommended to set it at 5~40mA);
