High-Voltage DC Test Sets HTS 20-10 are designed for testing dc dielectric strength of components, insulations, air- and surface flash-over gaps. Also for testing SPDs according to IEC 61643-1. The test voltage can be adjusted from 0.2 kV up to 20 kV.

The test voltage rises like a ramp from zero to the selected test voltage. The rate of rise can be adjusted from 100 V/sec up to 10000 V/sec. Then the test voltage remains at the selected value for the test time, which can be adjusted from 1 – 1000 sec. The actual test

voltage is displayed. The test can be repeated several times. If the output current exceeds the limit value, which can be adjusted, the high-voltage power supply is switched off and an error message is generated: sound signal and display. If an over-current occurs during rise of voltage, the spark-over The voltage is displayed.

In "current" mode, the test voltage increases in a ramp to the set current value.

Then the generator regulates the current value and measures the voltage at the test object. The adjustment range of the current is from 0.1 - 10 mA.

 The HV output terminals are located beyond a dielectric safety test cover with safety interlock. The transparent test cabinet prevents accidental contact with live parts of the test object and allows observation of the test object during testing.

It features a microprocessor-controlled user interface and a 7” touch screen unit for ease of use. The microprocessor allows the user to execute either standard test routines or a “user-defined” test sequence. A standard USB port provides the ability to print a summary of the test parameters to a USB stick.

The software program HTS-REMOTE allows full remote control of the test generator via Ethernet light guide as well as documentation and evaluation of test results, accordingly to the IEC 17025. To record definite impulses, it is equipped with an Impulse Recording Function (IRF) Moreover all generator functions may be computer-controlled via the isolated optical interface.

The generator excels by its compact design, simple handling and precise reproducibility of test impulses.
