From the basic fundamentals and principles of protective relaying to current research areas in protective systems and future developments in the field, this work covers all aspects of power system protection. It includes the implementation of relays using electromechanical devices, static devices and microprocessors; distance protection of high voltage and extra high voltage lines, including distance relay errors; and adaptive, dynamic, travelling wave and noise-based relays.and develops pressure in the transformer oil tank while lowering of the oil level in the conservator over time. For slowly developing faults, oil breakdown leads to a drop in oil level in the conservator and the float tilts, closing the mercury switch.
