Brahma Ignition transformer T13/M 15177081

The Brahma Ignition transformer T13/M 15177081 is a step-up transformer designed for use in burners operating on liquid or gaseous fuels. It operates with a supply voltage of 220 V 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%, power consumption of 145 W, and an input effective current of 0.65 A. It features a shell-type magnetic circuit, polyester resin insulation, and a centrally grounded secondary winding. The unit measures 110x96x78 mm, weighs 2 kg, and has an ingress protection rating of IP00.

When selecting an ignition transformer of this type, ensure that the supply voltage, frequency, and power ratings match the burner's requirements. The mounting system may vary; check the physical dimensions and mounting holes to ensure compatibility. The secondary voltage and current must be appropriate for the spark electrode gap, typically 3-5 mm. Also, verify the type of high-voltage connectors (e.g., plug-in 6.3 mm) and the length of the power cable.

Common failures include insulation breakdown leading to short circuits or open windings, which may result in weak or no spark. Overheating due to prolonged operation beyond duty cycle can cause internal damage. Symptoms include intermittent ignition, failure to ignite, or visible arcing. Check for continuity in windings, insulation resistance, and proper grounding of the RF suppression screen.
