This portable DC dielectric test sets check the electrical insulation quality of motors, power cables, etc.
The Dielectric Test Sets measure leakage current while applying a dc voltage at or above the insulation system¡¯s operating level. This measurement aids in determining the insulation system¡¯s ability to withstand overvoltages such as lightning strikes and switching surges.
This 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.
The test sets can be used to perform step-voltage and proof tests which, when incorporated into a routine maintenance program, can aid in predicting potential failure before breakdown occurs.
