An ANSI or IEEE standard is used for testing a capacitor banks. Tests on capacitor banks are conducted in three different ways. These are When a company introduces a new design of power capacitor, the new batch of capacitors must be tested to see if they meet the standards.
In making this evaluation, consideration must be given to the sensitivity of capacitor bank protection (such as unbalance protection) and the potential for a capacitor under test to inadvertently discharge stored energy into a protection system. In most cases secondary isolation of the protection system will be required.
Installed capacitor banks lose their ability to operate at optimal efficiency if they are not tested or maintained within a certain period of time. Capacitor functioning can deteriorate over time, lowering your power system’s power factor and leading to power factor loss.
A capacitor bank is static equipment. It must be examined at regular intervals to ensure proper maintenance. If they are not tested or maintained regularly, they can pose serious hazards to the industry. What are the Different Types of Capacitor Bank Tests? Testing capacitor banks is not a brief process. It involves several types of tests.
