The portable dc dielectric test sets check the electrical insulation quality of motors, power cables, switchgear, insulators, transformers and capacitors. Typical applications include acceptance and maintenance testing of critical equipment used by electrical utility substations and industrial plant distribution systems. Power apparatus manufacturers may also use the equipment to perform QA/QC production tests.
HiPot Testers available from Megger are used to test the dielectric strength of electrical insulation and ground circuit continuity of three-wire appliances and other devices, either in the field or at the end of a production line. All five instruments meet the UL 120 k-ohm requirement.
These compact, portable instruments incorporate all the latest features for dielectric withstand testing, have been designed in accordance with IEC1010 safety requirements for Installation Category II use, and meet UL requirements for such testing including:
• UL 1026 - Electric Household Cooking and Serving Appliances
• UL 544 - Electrical Medical and Dental Equipment
• UL 982 - Motor-operated Household Food Preparing Machines
• UL 1270 - Radio Receivers and Audio Systems
