How is the oil furnace ignition transformer tested for performance?

The oil furnace ignition transformer is tested for performance by measuring its output voltage and current under load conditions. This involves connecting the transformer to a test circuit that simulates operational conditions. Additionally, the transformer is assessed for insulation resistance and dielectric strength to ensure it can withstand high voltages without failure. These tests help verify that the oil furnace ignition transformer operates efficiently and reliably in power transformers.
