Introduction == The flicker of the house lights in the evening when most people are at home and started using electricity for household chores is a sign of a load tap changer (LTC) tap change. The increase in electrical load on the distribution network causes the voltage to sag below its nominal value. This voltage sage triggers a signal to the LTC to change taps to adjust the voltage back to its nominal value with some tolerance. There are many applications of tr...")
