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.
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.
- 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.
