What is the difference between loop terminal and line taps
Taps provide two or more voltages or are used to make adjustments to a nominal voltage to adapt to local line conditions. All taps work by essentially changing the primary to secondary winding ratio which dictates the input to output voltage ratio.
Loop Taps:
The coil's conductor is bent into a loop on the outside of the conductor and used to mount the tap conductor. This is a simple, cost effective method which doesn't involve heating the wire to braise a terminal pad.
Terminal Taps:
Sometimes referred to as lug taps, are created when a landing pad is braised onto a point in the coil to mount the tap conductor. This must be done with foil windings or typically when three or more conducting wires form the winding.
Line Taps:
Most taps are on the line side and primary coil of the transformer. This is typically the outer coil.
