OLTC Testing Using Dvtest

On-load tap changers, as the only moving part of a power transformer, are at risk to a large number of potential mechanical faults which can cause a failure of the entire transformer. DVtest method, which is an advanced version of dynamic resistance measurement (DRM), enables non-intrusive testing of all on-load tap changer types. It is especially useful in detection of open circuits during tap changer operation, various timing, motor or mechanical problems. Together with the winding resistance measurement, it reliably locates the exact location of the fault in the tap changer, which makes subsequent diagnostics and repairs faster and easier. Other complementary methods include motor current measurement and vibration testing.
