Brahma Ignition transformer T8 15000001

The Brahma 15000001 T8 ignition transformer is a column-type transformer designed for high thermal power burners and pressure burners operating on light or heavy oil, suitable for applications with frequent restarts such as steam boilers and kitchen ovens. It operates on a 220 V - 50 Hz supply, delivering two high-voltage outputs of 6.5 kV RMS (11 kV peak) with a secondary current of 33 mA and an ignition current of 35 mA. The transformer has a duty cycle of 33% in 3 minutes, consumes 460 W, and weighs 3.5 kg. Its body is made of pressed metal coated with enamel, and the insulation uses vacuum cast polyester resin. The device measures 101 mm x 80 mm x 150 mm and has an IP00 protection rating.

When selecting a replacement ignition transformer of this type, verify that the supply voltage, frequency, output voltage, and current ratings match the burner's requirements. Check the mounting system and overall dimensions to ensure compatibility with the existing bracket and connections. The transformer can be installed in any position, but the high-voltage cable length should be minimized to reduce parasitic capacitance. Ensure the grounding is properly connected to a single grounding center to avoid interference.

Common failures in ignition transformers of this kind include insulation breakdown leading to short circuits or open windings, often caused by moisture ingress or overheating. Symptoms on the equipment include weak or no spark at the electrodes, intermittent ignition, or burner lockout. Check the high-voltage cables for damage, verify the spark gap is within the recommended 3-5 mm, and measure the secondary voltage and current to confirm the transformer is functioning correctly.
