Consistency of Hipot Tests on Photovoltaic Modules
The field experience of HARREXCO AG is over 500MW/a and increasing. One of the most common questions which the company is confronted with, concerns the consistency of hipot values either expressed in electrical resistance or leakage current vs time or age. For instance, when a TF module laminated with PVB is in production and screened for hipot failure, the [...]
Hipot Electrical Safety Tests
Hipot is an abbreviation for high potential. Traditionally, Hipot is a term given to a class of electrical safety testing instruments used to verify electrical insulation in finished appliances, cables or other wired assemblies, printed circuit boards, electric motors, and transformers. The term Hypot is a trademark for hipot testers made by Associated Research.
A Hipot [...]
Notes to Keep in Mind when Purchasing Hipot Testers
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, [...]
Performing Safe And Accurate Hipot Testing in a Production Environment
Performing a routine product safety test should not in itself represent a shock hazard to the test operator. Yet, when working with an energized circuit, an operator must be aware of the hazards involved in performing the test and take the necessary safety precautions. The National Fire Protection Association (NFPA) Standard for Electrical Safety Requirements [...]
Investigating the Need for Hipot Testing
In an industry comprised of workers with varying electronics knowledge, a Hipot test can seem a daunting task for some. Indeed, many test operators and quality assurance supervisors, having never been trained in electrical engineering, have difficulty understanding the principles and setup of the test itself. Naturally, the mere mention of the more specific Hot [...]
What is a Hipot Test?
Many people don’t know what Hipot Testing is so I’ll briefly explain it.
Most people know what a continuity test is. A continuity test checks for good connections. Continuity tests are done by seeing if currents flow from point to point. If the currents flows easily the points are connected. “Hipot” is short for high [...]
