Brahma Ignition transformer T13/M 15177001

The Brahma T13/M 15177001 is an ignition transformer designed for burners operating on liquid or gaseous fuels. It operates on a 220 V supply at 50 Hz, delivering a secondary voltage of 8 kV and a secondary current of 16 mA. The transformer has a duty cycle of 100%, allowing continuous operation, and consumes 145 W. It features a shell-shaped magnetic circuit, polyester resin insulation, and a radio interference suppression screen. The unit includes two flame-retardant caps and is available with screw or cylindrical connectors.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and output voltage match the burner's requirements. The mounting system must be compatible with the burner's design; various mounting options are available, including standard and alternative systems. The connector type (screw or cylindrical) and dimensions must fit the existing ignition cable. The recommended spark distance between electrodes is 3–5 mm, and the power cable length is 550 mm.

Common failure modes for ignition transformers include insulation breakdown, leading to short circuits or loss of spark. Symptoms may include the burner failing to ignite, intermittent ignition, or visible arcing or burning smell. Check the transformer for physical damage, moisture ingress, and proper grounding of the radio interference suppression screen. Also verify the spark gap and cable connections.
