What is a 66kV and 220kV capacitor bank?

66kV and 220kV capacitor banks contribute to 89% of the total population mainly consisting of 66kV (70%), 220kV (19%) and other voltages (11%). Figure 2 below provides the capacitor bank rating range by voltage and most common average bank size is 50MVAr at 66kV. Capacitor bank ratings range from 5.4 MVAr to 158.4 MVAr.

What is a typical capacitor bank size?

Figure 2 below provides the capacitor bank rating range by voltage and most common average bank size is 50MVAr at 66kV. Capacitor bank ratings range from 5.4 MVAr to 158.4 MVAr. Figure 2 – Population of capacitor banks by nominal rating in MVAr

How many regulated capacitor banks are there?

The strategy covers the 59 regulated capacitor banks located in Terminal stations. The most common type being the 66kV 50 MVAr capacitor banks, that contribute to 36% of the capacitor bank population.

How many sets of capacitor bank should be installed outside?

Two sets of Capacitor bank shall be installed outdoor. Each set shall be 7.2 MVAR rated at 11KV comprising two sub banks of 3.6 MVAR each. Each sub bank shall be provided with motorized 11KV Isolator. It is intended to provide State-of-Art substation control, protection and metering system and shall be integrated with SCADA system.

What percentage of capacitor banks in terminal stations are C4 and C5?

Approximately 9.5% and 4.7% of capacitor banks in terminal stations are either in C4 and C5 asset condition respectively. These capacitor banks include the 66kV (12.7%) and 220kV (1.59%) of total population of capacitor banks.

What is a good condition capacitor bank?

The most common type being the 66kV 50 MVAr capacitor banks, that contribute to 36% of the capacitor bank population. Most capacitor banks are in reasonable health and 86% of the total population are either in a “very good condition” (C1), “good condition” (C2) or “average condition” (C3).
