Fundamentals of Dynamic Resistance Measurement (DRM) Theory, Testing, & Analysis (w/ Doble M7100) Webinar
Transformer reliability is dependent on the health of all subcomponents, notably the on-load tap changer (OLTC). On-load tap changers contain the only moving parts of a power transformer and introduce reliability risk should mechanical deficiencies exist. While conventional DC winding resistance measurements are performed in a static state, Dynamic Resistance Measurements (DRM) provide insight into the characteristics and condition of an on-load tap changer and contacts while transitioning between taps. The Doble M7100 offers DRM capability, with results recorded in the Doble Test Assistant (DTA) test file. This webinar will cover the M7100’s capabilities, test preparation and setup, and operation of the M7100’s DRM feature using DTA version 8.3.
Please note that is a virtual webinar for DSA clients.
