Hipot testing is a stress test to determine the reliability of insulators and helps identify bad components. There are different high potential testing technologies available and it is important to understand the proper use of each. Using the wrong method can degrade or even cause an electrical component to fail.READ MORE >>

High potential testing is conducted to determine if the cables can withstand normal operating voltages as well as over voltage conditions. There are specific tests suitable for field-aged cables as well as for newly installed cables. It is important to conduct the appropriate test in order to obtain as much information regarding the electrical health of the insulation without imposing detrimental effects in the process. Improper testing can lead to unexpected expenses and delays.
It is always recommended that electrical equipment be checked for problems even if it seems to be working fine, as electrical stress, normal weathering and contaminants can cause insulators to lose resistivity.READ MORE >>
Offered in either power frequency (50/60 Hz) or Very Low Frequency (VLF) models, AC hipots are capable of testing multiple types of substation apparatus, such as; motors/generators, isophase bus, and other loads requiring an AC withstand test.READ MORE >>

The HV Diagnostics TD90-MC is a versatile high voltage tan delta measuring system suitable for testing medium voltage electrical insulation systems such as cables (including: XLPE, PE, EPR, PILC etc.), capacitors, switchgear, transformers, rotating machines, insulators and bushings.READ MORE >>
The HV Diagnostics HVA90 90kV VLF / DC High Voltage Test Instrument features the ability to test MV and Sub Transmission class cables including 69kV cable and below. The HV Diagnostics HVA90 not only produces some of the highest VLF AC voltages available, but it also has a very powerful output capability, facilitating the testing of long cables.
Setup of the HVA90 is simple and automatic with no cumbersome interconnecting of various modules. Automatic test sequences can be setup directly on the instrument or on the supplied HVA Control Center software, and test reports are downloaded to the instrument’s internal memory or to a USB flash drive.READ MORE >>
Weak motor insulation often degrades to the point of causing premature and unexpected motor failure, which in turn can result in costly unplanned downtime of production machinery. The SKF (Baker) 12kV Static Motor Analyzer AWA-IV/12 is a fully-automated motor analyzer that automatically performs repeatable, user-programmable tests to thoroughly assess the strength of a motor’s insulation and circuit. The SKF AWA-IV/12 also used to assure quality of motor rebuilds or new production motors before they are placed into service.READ MORE >>
