Capacitor banks provide an economical and reliable method to reduce losses, improve system voltage and overall power quality. This paper discusses design considerations and system implications for Eaton''s Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
Moreover, the protection settings for the capacitor bank unfold systematically, elucidating the process of selecting the current transformer ratio, calculating rated and maximum overload currents, and determining the percentage impedance for fault MVA calculations.
Purpose: This guide has been prepared to assist protection engineers in the application of relays and other devices for 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.
IEEE 18 specifies certain physical dimensions for capacitor units, such as spacing between bushings and the mounting hole spacing. The spacing between bushings determines the maximum unit voltage rating, which is typically 20kV for two bushing units and 25kV for single bushing units.
Users should allow for capacitor units to fail during the service life of the capacitor bank and, accordingly, make provisions to facilitate their replacement. One such provision is the space required for personnel and equipment to access the failed units.
Capacitor bank protective schemes must be designed and applied to provide the signals required for protective relaying to perform as expected. This document provides guidance to help engineers draft comprehensive and clear purchasing specifications for capacitor banks.
When designing a capacitor bank, many factors must be taken into consideration: rated voltage, kvar needs, system protection and communications, footprint and more. These factors govern the selection of the capacitor units to be used, along with proper grouping of these units.
Capacitor banks provide an economical and reliable method to reduce losses, improve system voltage and overall power quality. This paper discusses design considerations and system implications for Eaton''s Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
