Ignition transformer voltage typical in oil burner systems is approximately how many volts?

• A. 5,000 volts
• B. 10,000 volts
• C. 15,000 volts
• D. 20,000 volts

Answer: (B)

Oil burner ignition relies on a high-voltage spark produced by the ignition transformer. The secondary voltage is set to reliably jump the electrode gap and ionize the air-fuel mixture under typical conditions. Around 10,000 volts provides enough potential to create a strong, consistent spark across the small gap and across varying temperatures, densities, and fuel quality. A lower value like 5,000 volts may not arc reliably in all situations, while higher values such as 15,000 or 20,000 volts are more than needed for most burners and require more insulation and can increase wear. Thus, about 10,000 volts is the standard, typical voltage for oil burner ignition transformers.
