A collection of capacitors of comparable ratings is known as a capacitor bank. These capacitors are arranged in parallel or series sequence to gather electrical energy. A capacitor bank is usually applied to an AC source of power. This helps to rectify or compensate for power factor lag or phase shift. These banks can also be connected to a DC power supply. This helps increase the comprehensive quantity of the power supply’s ripple current capacity or the stored energy. The primary use of a capacitor bank is to collect and store electrical energy to meet the operational requirements while ensuring the required power factor levels for the electrical equipment.
Now the question arises: what is the need for testing these banks, and how to test a capacitor bank. If you are curious to know the answers to the same, continue reading. This blog will list all the different types of tests conducted on capacitor banks, their importance, and their procedures.
The significance of capacitor banks in a power system can never be neglected as they play a crucial role in controlling the power factor correction. The power factor correction units perform various functions based on their location in the system. The power factor correction of capacitor banks changes due to moisture, temperature, time, and harmonics. To perform their best, the installed capacitor banks must be tested regularly and maintained to the highest quality.
Although capacitor banks of the finest qualities function quite well, their operation can weaken with time. This results in a decrease in the power factor of your system. Eventually, this leads to power factor loss. Therefore, it is essential to regularly test the capacitor bank and ensure its reliability and performance.
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.
Testing capacitor banks is not a brief process. It involves several types of tests. A professional technician tests a bank based on its type and requirements. Below are the different types of capacitor bank tests.
The type tests performed on capacitor banks are–
