DYNAMIC RESISTANCE MEASUREMENT – TAP-DRM
This accessory used with the TAP-4-PLUS instrument allows you to do dynamic resistance (DRM) testing which is a well-known test for assessing the condition of your OLTC.
According to CIGRE A2.34, the dynamic resistance measurements or DRM (OFFLINE test) offers diagnostics for several diverter or selector switch malfunctions such as: contact problems, broken springs, broken
transition resistors, poor contact pressure, inadequate transition time, momentary open circuit, and synchronism motion issues.

MAIN ADVANTAGES
- Detect anomalies or the wear of the tap-changer
- Easy correlation between vibro-acoustic, DRM and motor current
- Easy to use
- One accessory to do DRM
