It's installed on the high-voltage side.
The primary windings are bigger In size and it will be more accurate to tap it than tapping the smaller size secondary windings. Answer A tap changer is installed on the high-voltage side of a transformer, regardless of whether that transformer is a step-up or a step-down type. So, it isn't necessarily installed on the primary side of the transformer. The reason for this is that the current on the high-voltage side of the transformer is lower than on the low-voltage side, and the make/break contacts can be smaller. Also there are more turn on the high-voltage side so a finer degree of adjustment can be achieved.
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
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.
The size of any switch depends on current it carries. Your statement is true for step down transformers. The primary is HV hence less current, so the tap changer is on primary side.

Never come across one.
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.
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.
The tap changer changes the ratio of primary to secondary windings by physically adding or subtracting windings from the primary or secondary. An on load tap changer (LTC) allows dynamic voltage control, which is important when loading of transformers, and the system in general, varies (if the primary voltage sags, the LTC can be used to increase the secondary voltage so customers don't see this sag).
What?... Tell me what a tap changer is, and I may be able to help.

OLTC - INSTALLED IN THE PRIMARY SIDE OF A POWER TRANSFORMER TO SELECT OR ADJUST VOLTAGE. THE ADVANTAGE OF THIS IS FOR SOLVING THE VOLTAGE DROP ISSUES IN THE SECONDARY OUTPUT IN THE FARTHEST LOCATION. FOR EXAMPLE YOUR SECONDARY VOLTAGE REQUIREMENT IS 380 VOLTS AND YOU CAN ADJUST TO 400 VOLTS FOR LONG CABLE RUNS.
No. All a tap changer (whether 'off-load' or 'on-load') does is to make minor changes to the turns-ratio of a transformer.
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.
