Transformer Failures, Causes & Impactiieng.org/images/proceedings_pdf/8693E0215039.pdf· PDF fileThe tap changer function in the transformer is to regulate the voltage level. This is done by either adding or removing turns from the secondary transformer winding. It is the most complex part of the transformer and also an important one. Even the smallest fault results in the wrong power output [6]. The PN number is usually between 28 to 52.

ground fault detection current transformer | AVR Freaks· For ac detection the core balance technique works by measuring the difference in the active and neutral currents. With no leakage, these currents are equal. This is done by passing the active and neutral both through a current transformer. The current transformer now reads the difference in current.
