Moreover, surge arrestor protection is implemented for the capacitors, as illustrated in Figure 3, which depicts the single-line diagram of the capacitor bank. Three surge arrestors are installed, with one safeguarding each phase. Figure 2 – Double Star Connection: Illustration of Capacitor Bank Configuration
What is a pad-mounted capacitor bank?
Pad-mounted capacitor banks ( suitable for indoor or outdoor installation ) are described in the installation instructions (Figures 1 and 3). Their enclosures are typically constructed using mild carbon steel with a powder coating.
What are the protection settings for a capacitor bank?
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.
How do you install a capacitor bank?
Insert the two 3/4-in. bolts through the holes, using washers and lockwashers as needed. Thread the nuts onto the bolts but do not tighten. Using the lifting eyes on the capacitor bank frame, lift the capacitor bank, positioning it at the pole so that the bolts can slip into the slots on the capacitor bank pole-mounting bracket.
