Transformer Tap Changer | Why OLTC Monitoring Important | Onload Tap Changer | Offload Tap Changer

Tap changers are devices that can increase or decrease the output secondary voltage by changing the turn ratio of primary or secondary winding. A tap changer is usually installed on a high voltage section of a two-winding transformer, due to the low current in that area. The changers are also provided on high voltage windings of an electrical transformer if there is sufficient control of voltage. The change of voltage is affected when you change the number of turns of the transformer provided with taps.
