Question

List standard voltage level used in India.

Answer 1

In India, the standard voltage levels used for various applications are as follows:

1. Household/Residential Voltage:
   

   - Voltage: 230V
   - Frequency: 50 Hz
   - This is the standard voltage for most home appliances like fans, refrigerators, and lights.

1. Low Voltage for Appliances:
   

   - Voltage: 110V or 12V (for small appliances or battery-operated devices)

1. Medium Voltage:
   

   - Voltage: 11 kV (Kilovolt)
   - This is typically used for distribution networks from substation to areas that need medium voltage.

1. High Voltage:
   

   - Voltage: 33 kV to 66 kV
   - Used for regional distribution to provide power to large areas.

1. Extra High Voltage:
   

   - Voltage: 110 kV, 132 kV, 220 kV, 400 kV
   - These high voltage levels are used for the transmission of electrical power over long distances, helping reduce energy losses.

1. Ultra High Voltage:
   

   - Voltage: 765 kV
   - Used for long-distance, high-capacity transmission, helping to move large amounts of power across the country.

These voltage levels are aligned with the guidelines set by the Bureau of Indian Standards (BIS) and international standards for electrical systems.
