Brahma Ignition transformer T8 15000091

The Brahma T8 ignition transformer (SKU 15000091) is a column-type transformer designed for high output or pressure burners using light or heavy oil. It operates at a supply voltage of 220 V and 50 Hz, with a secondary voltage of 6.5 kV and a secondary current of 33 mA. The transformer has a duty cycle of 33% in 3 minutes, power consumption of 460 W, and an input effective current of 2.1 A. It features a pressed metal body coated with enamel, polyester resin insulation, and dimensions of 101x80x150 mm, weighing 3.5 kg. The recommended spark distance is 3–5 mm, and it includes a standard power cable length of 700 mm with 2 poles.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and secondary voltage match the burner's requirements. The mounting system and dimensions must be compatible with the existing installation; variations exist in connection types, such as screw terminals or 6.3 mm rajah cylindrical terminals. Verify the number of poles and the physical dimensions (length, width, height) to fit the available space. The duty cycle and power consumption should also be considered to match the operational demands of the system.

Common failures in ignition transformers of this kind include insulation breakdown, leading to short circuits or loss of spark. Symptoms may include intermittent ignition, no spark, or excessive noise during operation. Check for visible damage to the body or terminals, and measure the secondary voltage and current to confirm proper output. Overheating or tripping of the burner control may indicate internal winding faults.
