Transformers may be supplied with an LTC (load tap changer) that physically adds/removes windings from one side to control the voltage output of the transformer. If the LTC is moving, it is referred to as "tapping". An LTC has several discrete tap positions. The ones I see most often have 33, 16 up, 16 down, and a neutral.

What do you mean by tapping of transformer?

'Tappings' are externally-accessible electrical connections to the turns of a transformer's (usually high-voltage) winding. This enables the number of turns to be changed, resulting in a change to the transformer's turns ratio and, therefore, to its voltage ratio. Tap changing enables the electricity network company to adjust the turns ratio in response to any excessive voltage reduction resulting from a heavy load.


Why oltc is situated on primary side of traformer?

oltc is situated on primary side of transformer because by primary side we can obtain fine voltage change by tapping with low current flow through it.

Why you are using on load tap changer in primay of transformer?

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.


What is In-Die Tapping?

In-die tapping is the process of tapping stamped parts in a progressive die while in a punch press. In-die tapping eliminates the need for a secondary tapping operation of stamped parts.

What is on-load tap-changing?

On-load tap-changing is done in electric power supply systems to maintain the supply voltage to customers within limits. Tapping is done by switching extra turns in or out, usually on the high-voltage winding of a transformer. The switching is done by a make-before-break switch to avoid excessive sparking in the transformer, and this enables the switching to be done without interrupting the supply.
