HM-K10A High Voltage Bridge Tester

Used for locating a variety of wire and cable breakdown point or no breakdown but low insulation resistance value defect point, and high-voltage cable protection sheath faults. It can also be used for cable factory to test cable defects.

High voltage constant-current power and bridge are integrated in a portable industrial cabinet. Therefore, the device has high voltage, light weight, easy to operate and safe to use.

Introduction

HM-K10 high-voltage bridge locator is based on the MURRAY bridge principle. It is used for locating a variety of wire and cable breakdown point or no breakdown but low insulation resistance value defect point, and high-voltage cable protection sheath faults. It can also be used for cable factory to test cable defects.

The device using SMPS to constitute the high-voltage constant current power,no-load voltage is -15000V,short current is 30mA. Using high sensitivity amplifier and galvanometer to indicate balance, with proportional potentiometer to constitute a balanced bridge and placed at high potential. The testing wire is specially designed dual-core high voltage rubber cable.

Use four-terminal resistance measurement to avoid the error arising from lead resistance,the test wire is reliably grounded through a braided shield,the operation button on the panel is at earth potential, operate the bridge through the insulation bar.high voltage constant-current power and bridge are integrated in a portable industrial cabinet. Therefore, the device has high voltage, light weight, easy to operate and safe to use.


Function and application

HM-K10 High voltage bridge tester have three function:

DC withstand test: the device can output 0 ~ 15kV DC voltage, can be used in cable dc voltage withstand test.

burn-through fault point: burn-through or reduce the high resistance and flashover fault point resistance.

Fault pre-locating:using bridge principle to pre-locate,four-terminal resistance measurement method to avoids the error arising from lead resistance.

Meanwhile, HM-K10A high voltage bridge tester is particularly suitable for:

Installed cable high resistance breakdown point, in particular for the linear HV breakdown point which is difficult to burn to low resistance, such as cable middle connector linear high resistance breakdown.

Flashover breakdown point, after breakdown the constant current power can maintain the arc, a stable current through the bridge, the bridge has enough sensitivity.

 Not yet breakdown but low resistance fault, for example, megger shows cable resistance is low, but under operating voltage the insulation defects can not be breakdown.
