Brahma Ignition transformer T18 15510001

The Brahma Ignition transformer T18 15510001 is a column-type transformer designed for continuous operation in ignition systems for liquid or gaseous fuel burners. It operates at a supply voltage of 220 V and 50 Hz, with a power consumption of 170 W. The transformer provides a secondary current of 18 mA and an ignition current of 16 mA, with a duty cycle of 100%. It features two primary and two secondary windings, insulated with vacuum-cast polyester resin, and has a pressed metal body coated with enamel. The unit measures 150 mm in length, 101 mm in width, and 80 mm in height, with a net weight of 3.7 kg.

When selecting a replacement ignition transformer of this type, ensure that the supply voltage, frequency, and secondary current match the system requirements. The mounting system and dimensions must be compatible with the existing installation; various connection and fastening systems are available. Check the recommended spark distance (3–5 mm) and the standard power cable length (700 mm) to ensure proper fit. High voltage cables should be routed away from other cables to avoid interference, and the transformer must be disconnected from the power source before installation.

Common failures in ignition transformers of this kind include insulation breakdown leading to short circuits or open windings, which may result in weak or no spark at the electrodes. Symptoms on the equipment include ignition failure, intermittent burner operation, or a noticeable drop in spark intensity. Check the transformer for signs of overheating, enamel damage, or cracks in the resin insulation, and verify the output voltage and current with appropriate test equipment.
