Included are guidelines for reliable applications of protection methods intended for use in many shunt capacitor applicatio

44、ns and designs. The guide does not include the protection of pole-mounted capacitor banks on distribution circuits or capacitors connected to the terminals of rotating machines. 1.2 Purpose This guide has been prepared to assist protection engineers in the application of relays and other devices for

45、 the protection of shunt capacitor banks used in substations. It covers methods of protection for many commonly used shunt capacitor bank configurations including the latest protection techniques. Additionally, this guide covers the protection of filter capacitor banks and large extra-high-voltage (
