The taps for power transformers usually vary within a range of ±10%, but can alternatively be +5% or –10% or similar. For distribution and service transformers up to 2 MVA, use taps with a tolerance of ±5%. The typical tap changers have a range of ±10% in increments of 0.625%, but Off-LTCs often have 2.5% increments.

6 FAQs about [Power distribution main backup line]
Do distribution substations need a DG backup?
It is advised that each distribution substation should have its own DG Backup so that in case of mains power loss local DG sets are available as backup as per the standard procedure. Having a centralized DG Backup to provide 11 KV DG Power to the distribution substations is not advisable.
What is an electric power distribution system?
Electric power distribution systems are designed to serve their customers with reliable and high-quality power. The most common distribution system consists of simple radial circuits (feeders) that can be overhead, underground, or a combination.
Why should a substation have a backup system?
Hence, in order to ensure continuous supply, it is imperative to have backup systems in place. To ensure redundancy, two 1000 kVA transformers should be placed at the substation, each capable of handling the whole load. This arrangement allows for seamless operation in the event of a breakdown in one of the transformers.
How to ensure uninterrupted power supply to ups loads?
To ensure uninterrupted power supply to UPS loads, a UPS system is given for the specified period of time. The DG Sets and UPS system are equipped with standby units to ensure an uninterrupted power supply system, in conjunction with the mains supply.
How does a power substation convert a transmission to a distribution?
The place where the conversion from "transmission" to "distribution" occurs is in a power substation. A power substation typically does two or three things: It has transformers that "step down" transmission voltages (in the tens or hundreds of thousands of volts range) down to distribution voltages (typically less than 10,000 volts).
Should DG backup be centralized?
Having a centralized DG Backup to provide 11 KV DG Power to the distribution substations is not advisable. This will prevent the segregation of essential and non-essential resources. In the event of any malfunction in the 11 KV feeder cable, the entire campus will be without DG Backup.
