*The equipment adopts switching power supply to form high voltage constant current source, high voltage and stable current. *The bridge detection module is integrated with a large LCD screen display at high potential. The operating button on the panel is at ground potential and the bridge is operated through the insulation rod.
*The special custom-made four-core high-voltage measuring cable with shield, the copper mesh braided shield layer is reliably grounded and safe to use. The four - end resistance measurement method avoids the error of lead resistance.
*The high voltage constant current source and bridge are integrated in a portable pull rod plastic box. High voltage, light weight, easy to operate.
*The bridge method has no blind spot compared with the wave reflection method, and is especially suitable for determining the breakdown points of short cables and near the ends.
*High voltage and high current are especially suitable for the fault locating of insulation and sheath of complex high-voltage cable systems with large length and large section.
