What specifications define an ignition transformer for an oil burner system?

Specifications include primary voltage and frequency, secondary output voltage typically 8-12 kV, rated secondary current suitable for stable spark, duty cycle rating, insulation class, and environmental temperature rating. Mechanical specifications include mounting footprint, terminal style, and enclosure protection. Some applications require continuous duty while others are intermittent. Compatibility with the burner control system and safety approvals are important. A correctly specified ignition transformer delivers consistent spark energy without overheating or excessive electromagnetic noise.
