Document insulation-test results

Insulation measurement instruments

Choose equipment only after the approved test method and equipment scope are known.

What to compare

Application boundary

An insulation tester does not replace a voltage detector or establish overall equipment health. Cable diagnostics and specialized transformer tests may require other instruments.

Before purchasing

Confirm the approved test method, instrument ratings, compatible leads, calibration support, and operator training. Use current manufacturer documentation. Specialist systems may require a manufacturer or specialist supplier rather than a general marketplace.
