# Technical Guide to Industrial Insulation Resistance Testing for High-Voltage Motors

## Overview of Insulation Testing

Insulation resistance testing is a critical diagnostic tool for assessing the condition of high-voltage motor windings.

## Testing Procedures

Standard procedures include the use of a megohmmeter to apply a DC voltage and measure the resulting current.

### Interpretation of Results

Results should be trended over time to identify gradual degradation of the insulation system.
