Provide ground instantaneous overcurrent protection for the capacitor bus and bank. Provide sensitive ground time overcurrent protection supervised by a 59N relay measuring bus 3V0 that would deliver backup protection for each stack''s protection. Provide primary voltage unbalance protection for each capacitor stack.
ABB's capacitor bank protection is used to protect against faults that are due to imposed external or internal conditions in the shunt capacitor banks. Internal faults are caused by failures of capacitor elements composing the capacitor units, and units composing the capacitor bank.
The capacitor bank frames are available in 3, 6, 9, and 12 unit configurations. The frames are designed to support the capacitor units and other optional components. The frames are also designed to maintain the proper electrical clearances of the components mounted on the frame. PROVIDED FOR CUSTOMER GROUND. WIRE RANGE: #12 SOL. - #1 STR.
Abstract: High-voltage (HV) capacitor banks are constructed using combinations of series and parallel capacitor units to meet the required voltage and kilovar requirements. These capacitor banks utilize protective relays, which will trip the bank when problems are detected.
Bank stability for a fuseless capacitor bank is similar to that of an externally fused capacitor bank and defined by shorted series sections, internal to individual capacitors. The voltage on the remaining series sections in the string should not exceed 110% of its rated voltage.
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.
Internal faults are caused by failures of capacitor elements composing the capacitor units, and units composing the capacitor bank. Other faults inside the bank can be a flashover within the rack (short circuit over a single or multiple series groups of units of the same phase) and rack phase-to-phase and phase-to-earth faults.
