Construction

The ignition units BRAHMA T11/M 15093001 has a magnetic circuit design in the form of a shell. The secondary windings of this transformer are grounded in the center. To suppress radio interference, the BRAHMA T11/M 15093001 transformer with ignition cable has a shield that must be securely grounded for efficient operation. Two caps painted with flame retardant paint cover the coils and combine with the magnetic circuit into a single unit.

Each transformer is designated by the letter T (denoting “transformer”), followed by a series of numbers indicating the model, and sometimes a letter of the alphabet defining a specific mounting system. If a standard mounting system is used, the corresponding letter is not mentioned in the part designation. For example, T11 refers to a transformer with a standard mounting system, while T11/N indicates a T11 transformer with a different mounting system.

The ignition devices BRAHMA T11/M 15093001 may have the same electrical characteristics, but differ in the mounting system or vice versa.

Connection

The BRAHMA T11/M 15093001 transformers use high-voltage insulators, which are divided into two types depending on the method of connection to high-voltage cables. The connection can be made using a screw, a cylindrical terminal with a diameter of 4 mm or a cylindrical terminal with a diameter of 6.3 mm. Unless explicitly stated, a screw terminal is used as the connecting terminal.

Spark transformers BRAHMA T11/M 15093001 are made of PBT material with a content of 30% fiberglass.

Installation

• Attention! Dangerous voltage may be present.
• Connect and disconnect the ignition transformer only after the power supply is completely disconnected.
• Comply with applicable national and European standards (e.g. EN 60335-1 / EN 60335-2-102) on electrical safety.
• Ensure that the transformer ground is securely connected to the electrical system ground.
• Install a single grounding center, preventing the creation of ring tracks from the grounding wires.
• The ability to install the device in any position.
• Minimize the length of the ignition cable (to reduce parasitic capacitance and prevent the ignition cable from acting as an antenna that emits interference to adjacent cables).
• Route the ignition cables along a separate path near the ground planes (to reduce interference to other electrical wires).
• Avoid placing high voltage cables next to other cables.
• Check that the degree of protection meets the requirements of the system.
