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.
AC hipots of the power frequency variety are used for testing vacuum bottles, switchgear, reclosures, circuit breakers, etc. These units will typically offer ratings of 3 to 7 kVA.
VLF hipots are preferred for testing high capacitance loads such as cable, large rotating machinery and occasionally large insulators and arrestors.
Protec Equipment Resources offers a large inventory of both power frequency AC hipots and VLF AC hipots from leading manufactures for rent today.
