What is off load tap change?
Tap changer is a device that is used to change the secondary voltage on transformers. It is normally on the HV winding of the transformer. Off load tap changer is designed to change the taps only when the transformer is not charged, while on load tap changer is capable of changing the tap on load too.
What is the difference between off load tap changer and on load tap changer?
An on-load tap-changer must not break the supply to the transformer's windings while the transformer is on load. So it has a 'make-before-break' arrangement with its contacts -i.e. one contact moves to the second tap setting, before the second contact moves away from the first tap setting, while a reactor balances the load currents when the contacts are on different tap settings. An on-load tap changer is motor-driven, and can be operated automatically or manually.An off-load tap-changer does not require a make-before-break arrangement, because it is designed to be operated when the transformer is disconnected.
What is on load tap chenger?
A tap changer is used to vary the turns ration between the windings of a transformer to make minor changes to the secondary voltage. An on-load tap changer enables the turns ratio to be altered without disconnecting the transformer. An off-load tap changer requires the transformer to be temporarily diconnected. On-load tap changers are installed on the high-voltage side of the transformer, where the current is lower.

What is inherent voltage regulation of an onload tap changer for power transformer?
depending on the amount of the load of transformer as well as the power factor of it, there is a transformer specific voltage drop at its terminals, due to the internal impedances. The on-load tap changer can / will be used to compensate this voltage drop or rise.
When you need to change the position of the tap changer?
What?... Tell me what a tap changer is, and I may be able to help.

Off load tap changer is designed to change the taps only when the transformer is not charged, while on load tap changer is capable of changing the tap on load too.
What is the difference bet manual off Tap changer and auto tap changer in Distribution Transformers?
automatic tap changing transformers can change their tap setting on their own, manual tap means a person has to manually go out and change the tap setting
Is an on-load tap changer considered as a resistor?
No. All a tap changer (whether 'off-load' or 'on-load') does is to make minor changes to the turns-ratio of a transformer.

How does on load tap changers operate?
On-load tap-changers are operated by an electric motor, often by driving a flywheel mechanism. The operation of the tap-changer is controlled by an AVR (automatic voltage regulator) which monitors the transformer's secondary voltage.

Why was the tap changing panel removed from a transformer?
So that tap-changing can't be done any more, or maybe the tap changer was faulty.

Is it possible to play tap tap revenge online?
No it is not possible.
When operating a no load tap changer on a transformer what should be done first?
First isolate the transformer
How to use Tap position indicator?
A Tap Position Indicator (TPI) is utilized in power transformers to monitor the position of the tap changer, which is responsible for adjusting the transformer winding to control voltage levels.
