Brahma Ignition transformer T18 15510101

The Brahma T18 ignition transformer (SKU 15510101) is a column-type transformer with a supply voltage of 220 V and a frequency of 60 Hz. It provides a secondary voltage of 4.5–4.5 kV with a secondary current of 18 mA and an ignition current of 16 mA. The transformer has a power consumption of 170 W, a duty cycle of 100%, and is suitable for high thermal output burners, light and heavy oils, and steam boilers. Its body is made of pressed metal coated with enamel, and it uses vacuum-cast polyester resin for high voltage insulation. The transformer weighs 3.7 kg and has dimensions of 150 mm x 101 mm x 80 mm.

Parts of this type are selected by matching the supply voltage, frequency, and secondary voltage/current to the burner's ignition system. Mounting systems vary, and the model number may include additional letters indicating the specific mounting type; if no letter is present, a standard fastening system is used. High-voltage cables are connected either via screw connections or 6.3 mm diameter cylindrical rajah terminals. Ensure the grounding is properly connected and the installation position is any, but avoid placing high-voltage cables near other cables.

Typical failures include insulation breakdown leading to short circuits or open windings, which may cause weak or no spark. Equipment may fail to ignite or exhibit intermittent ignition. Check for visible damage to the body, loose connections, and measure the secondary voltage with a suitable probe to verify output.
