The HiPot test instruments you need for good insulation isolation

Our High Voltage or High Potential Testers (HiPot) are used to test the integrity of the insulation and detect material or workmanship defects of one or more components of an electrical system. A hipot test, otherwise known as Dielectric Withstanding Voltage (DWV) test can determine if the insulation of a product or component is sufficient to prevent electrical breakdown and also protect users from electrical shock. In any electrical installation, insulation is one of the most crucial elements. Insulation testing can be a very useful tool to determine if a system is ready to energise or if a system that has been in service is starting to deteriorate.
HiPot Test instruments are used to conduct tests using normal rated voltage (or higher than rated voltage) of an electrical system to ensure the insulation is fit for service. AC and DC Hipot testers are available for hire depending on the required tests and can be used for High Voltage Busbars, Circuit Breakers, Bushings, Isolators, Cables, Transformers, Generators, Inverter systems and Switchboards.
Low voltage wiring can also be tested using a HiPot tester (sometimes called an LV Flash Test) to ensure the integrity of all cabling and equipment in a switchboard factory prior to dispatch to a customer, for example.

Importance of HiPot Testing

HiPot testing is a non-destructive test that confirms the integrity of your electrical insulation. This is a high-voltage test that determines whether insulation is deteriorated, damaged or contaminated
A HiPot test can be useful in determining the following:
• Nicked or crushed insulation
• Cracked insulation
• Stray wire strands
• Problems with poor earthing or shielding
• Conductive or corrosive contaminants
• Terminal spacing problems
• Cable tolerance errors
• Clearance encroachments
• Insulation deterioration
Our high potential testers from Brandis Hire offer an easy and complete solution for testing, protecting, and measuring insulation according to IEEE and IEC standards.

AC and DC HiPot Testers

Most safety standards will permit the use of either AC or DC voltage when performing a HiPot test. The type of tests (AC/DC) being performed will be dependent on the equipment being tested and acceptance criteria.

DC Voltage HiPot Testers

When you’re testing using DC voltage, it’s important to ensure that the test voltage is correct for the equipment under test and the insulation is not being stressed unnecessarily.
Using a DC test voltage allows the leakage current trip to be set much lower than when using an AC test voltage. DC Hipot testing is often used on older paper-lead style HV cables and can also be used to test an insulation system, where capacitive and inductive properties cause problems for AC Hipot testing.
Safety first! If you are using a DC HiPot tester, following any test, there may be a residual charge present and you will need a safe discharge device or a setup. A good practice when doing any Hipot testing is to ensure the equipment under test is discharged before it is handled.

AC Voltage HiPot Testers

When testing with an AC HiPot tester, you are in effect, testing as close as possible to real operating conditions, with test voltages often exceeding the rated operating voltage. This is one of the best methods of ensuring a piece of equipment to is fit for service and OK to be energised or returned to service.
