Capacitor Banks | MV and HV Cap Banks | Southern States
When a capacitor switch opens, the voltage across the contacts combines system and capacitor bank voltages. This can cause re-strikes, generating overvoltages approaching up to 3 p.u. Re-strikes can trigger issues like ruptured capacitor cans, blown fuses, and contact wear, leading to dielectric failures.
Capacitor Bank Switching and HMI Subsystem Reference …
• Capacitor bank: The capacitor bank is a critical component of APFC panel. Each capacitor can be individually fused with an appropriately sized current limit fuse. • Capacitor bank switching: – Conventional switching — Contactor: Contactors are electrically controlled switches for handling higher currents.
Smartbank™ Medium-Voltage Pole-Mounted Capacitor Banks
Pole-mount power factor correction capacitor banks, whether switched or fixed, are supplied on self-supporting aluminum racks. Six-position rack comes standard even if only three capacitors are required, thus allowing the customer to expand the capacitor bank in the future by merely inserting the additional capacitors.
