On-load Tap Changer (OLTC) Transformer
Operation: Adjusts the voltage level while the transformer is under load and without interrupting the power supply.
Advantages: Ideal for areas with frequent voltage or load instability, as it allows for real-time voltage regulation and control.
No-load Tap Changer (NLTC) Transformer
Operation: Adjusts the voltage level only when the transformer is de-energized, requiring a power outage to make adjustments.
Advantages: More economical, suitable for areas with stable voltage conditions.
Recommendation
Unstable Voltage or Load: Choose an OLTC transformer to maintain better voltage regulation and control without power interruptions.
Stable Voltage: Choose an NLTC transformer for its cost-effectiveness, as real-time adjustments are unnecessary.
