Description
Description
This product is mainly used for sampling impulse discharge of high-resistance fault waveform during fault testing of 35kV and below power cables and for impulse discharge when the fault point is accurately located. The sheath is used at precise points, and the burn-through capability can burn through the breakdown point in a short time and reduce the breakdown point resistance.
Feature
Integrated design, built-in capacitor, simple wiring.
Touch screen human-computer interaction, simple setting operation, intuitive and convenient display of instrument status.
With voltage regulation, automatic voltage regulation and automatic protection functions.
The output high voltage has the function of single pulse and continuous pulse, respectively cooperate with the fault tester and the fixed point instrument to find the fault point.
The output high voltage has a DC output, which can be connected to an external ball gap for work, and the application is diversified.
Software controls vacuum shock spark discharge, self-adaptive discharge and pulse cycle.
With emergency stop button, automatic discharge function, automatic voltage reduction and discharge after emergency stop or shutdown, safe and reliable.
The continuous working time is not less than 6 hours, which meets the longest working time of the cable fault test.
Engineering chassis design, compact structure.

Why is it necessary to measure the absorption ratio of electrical equipment?The absorption ratio is defined as follows: When operating a megohmmeter (insulation resistance tester), rotate the handle at a speed of 120 revolutions per minute. Record the insulation resistance reading at 15 seconds (R15) and then at 60 seconds (R60). The absorption ratio is calculated using the formula:Absorption Ratio = R60 / R15, which should be greater than or equal to 1.3.Measuring the absorption ratio helps determine whether the insulation of electrical equipment is damp.
