Electrical power supply is vital for ensuring reliable and efficient service. Several quality parameters must be monitored to maintain stable and safe electricity delivery to consumers. These parameters include:

1. Voltage Stability: This refers to maintaining a consistent voltage level within an acceptable range. Fluctuations or voltage dips (sags) and surges can damage electrical appliances and disrupt operations. Voltage regulation ensures that the supply voltage remains within the prescribed limits to avoid these issues.

2. Frequency Stability: The frequency of the electrical power supply, typically 50 Hz or 60 Hz depending on the region, should remain constant. Any deviation from the nominal frequency can affect the performance of machines and equipment that are sensitive to frequency changes, such as motors ______ _____ ____ ___ __________ __________ ______ __________ ___ ______ ___.
