One of these safety requirements involves a test for high voltage, as this provides a way to understand the whether electricity poses a hazard in some circumstances – in this article, we take a look at why a high voltage test is so important. Getting started with high voltage testing
The main purpose of of the high voltage DC test is to determine the insulation strength and performance of electrical equipment and components when they are operated on high voltage DC supply. In practice, this test is commonly used in testing of equipment used in HVDC transmission systems.
Provided by the Springer Nature SharedIt content-sharing initiative Policies and ethics High-voltage (HV) testing utilizes the phenomena in electrical insulations under the influence of the electric field for the definition of test procedures and acceptance criteria.
During high voltage testing of electrical equipment, several different types of tests are performed, they are, Dielectric Breakdown Test High Potential Test Partial Discharge Test Insulation Resistance Test Flashover Test Sustained Low-Frequency Test High Voltage DC Test High Voltage Frequency Test Surge Test or Impulse Test
Generally, though, a high voltage test will be carried out using long probes to ensure a safe distance between the user and the system under test, as high voltage electricity can travel through the air and does not require a person to touch the live parts of the device. Why are high voltage tests performed, though?
Principle circuit of a HV test system The HV generator (HVG) converts the supplied low or medium voltage into the high test voltage. The type of the generator determines the kind of the test voltage. For the generation of high alternating test voltages (HVAC), the HVG is a test transformer (Fig. 2.6 a).
