Hipot testers are electrical safety test devices that perform electrical compliance tests. Within the general category of electrical safety testing are a variety of equipment types that are specifically designed to test for electrical compliance. The individual equipment defines the kind of test performed.  Types of measurement performed by hipot testers include AC dielectric strength, DC dielectric strength, arc detection or tracking, insulation resistance, AC/DC selectable, and earth...

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using hipot testers?
6 answers
Answers:
DC testing is no longer recommended by most and is very limited in application - there are products on the market that have both +DC, -DC and VLF capabilities. PD testing is now becoming a std requirement in commissioning and maintenance. Invest a little more and get a PD-free hi-pot tester.
~Paul V, Engineering Business Manager, Perth, Australia
Buy a hipot that will deliver the rated current at rated voltage.
~Paul W, Engineer, Grantsville, MD
It is important to check how safe the device is for the operator.
~Shrinivas Piddugu, Engineer, Pune, India
Safety must have highest priority, keep them simple.
~Jim G, Technical Support, Dubai, United Arab Emirates
Use a consultant.
~Willie B, High voltage network cable splicer, Madison, Madison
Use it first.
~Stan B, Engineer, Houston, TX

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of hipot testers?
