OLTC stands for various terms. Discover the full forms, meanings, and possible interpretations of OLTC across different fields and industries.
A tap changer that is not designed for operation while the transformer is supplying load.
OLTC means On-Load Tap Changer. It is a part of a power transformer. A transformer changes high voltage to low voltage, or low to high. But sometimes the voltage goes too high or too low when people use more or less electricity. OLTC helps to keep the voltage at the right level. It can change the voltage steps (called "taps") while the transformer is working. This is very useful because we do not need to stop the electricity to make the change.
OLTC works when the power is on. This means it can control the voltage without turning off the transformer. This is important for cities, hospitals, and factories because they always need electricity. If the voltage is too low or too high, machines can get damaged. OLTC helps to give safe and steady power. It works automatically or with a control system. That makes power systems smarter and safer.
