Frequently Ask Questions
Q. What is the function of on-load tap changer?
A. An on-load tap changer (OLTC) regulates the output voltage of a transformer by adjusting the winding taps without interrupting the power supply, ensuring continuous voltage stability under varying load conditions.
Q. What is the difference between onload and offload tap changer?
A. The key difference is that an onload tap changer (OLTC) can change taps while the transformer is energized, whereas an offload tap changer (NLTC) requires the transformer to be switched off before changing taps.
Q. What is NLTC?
A. NLTC stands for No Load Tap Changer, also known as an offload tap changer, which allows voltage adjustment only when the transformer is de-energized.
Q. Why do we use OLTC?
A. We use OLTC to maintain a constant output voltage under fluctuating load conditions, especially in power distribution systems where voltage stability is critical without interrupting the electrical supply.
Q. Is OLTC automatic or manual?
A. OLTCs can be both automatic and manual. In most modern systems, they are automatic, controlled by a voltage regulating relay that adjusts taps based on real-time voltage levels.
Q. What is the working principle of transformer?
A. A transformer works on the principle of electromagnetic induction, where alternating current in the primary coil creates a changing magnetic field that induces voltage in the secondary coil, allowing voltage conversion without direct electrical contact.
