What is the secondary voltage of an ignition transformer?

An ignition transformer is designed to produce a high voltage that is necessary for igniting the fuel in combustion systems, such as oil burners. The commonly accepted voltage range for secondary ignition transformers used in these applications typically falls around 10,000 volts. This level of voltage is critical for ensuring that a sufficient spark is generated to ignite the fuel.

The choice of 10,000 volts as the secondary voltage indicates that it's adequately balanced for efficient ignition while being manageable in terms of safety and equipment design. Higher voltages would not necessarily increase the efficiency of ignition and could introduce additional risks and complexities.

Understanding the specification of ignition transformers is crucial for correct installation and maintenance of heating systems, as an incorrect voltage could result in poor performance or unsafe conditions.
