Variants
Our ignition transformers (ignition transformers) are suitable for high-voltage ignition of gas burners or oil burners. The ignition transformers, also known as transformers, can also be used on burners with single-electrode operation. The ignition current and the ionization current flow through a common electrode. Our ignition transformers are used by Honeywell among others and correspond to the variants TZI and TGI in their range.

Examples
Two-electrode operation
Ignition via ignition electrode
The ignition transformer TGI is supplied with voltage by the gas combustion machine IFD 258. The ignition transformer generates a high voltage and this high voltage creates ignition sparks between the ignition electrode and the burner ground. After the burner start, the current flows through the ionization electrode for flame monitoring.
Single-electrode operation
Ignition takes place via an ignition and ionization electrode. After When the burner starts, a flame monitoring current flows via the same electrode that is used for ignition.

Definition of ignition transformers
Ignition transformers are specialized transformers that are used in applications such as gas burners or high-voltage testing devices for precise ignitions. These transformers play a crucial role in generating the high-voltage pulses required for the safe and reliable ignition of burners and other high-energy systems.
How the ignition transformers work
The ignition transformer consists of a core and at least two windings: the primary winding and the secondary winding. The primary winding is supplied with a low voltage and generates a magnetic field in the core. This magnetic field is then transmitted through the secondary winding, generating a high voltage. This high voltage is used to ignite gas burners or other high-energy systems.
Design of the ignition transformers
The core of ignition transformers is often made of laminated iron or other materials with good magnetic properties. The windings are carefully insulated to ensure safe energy transmission. The design is designed to generate high voltages with precise pulses to enable reliable ignition.
Areas of application for ignition transformers
Ignition transformers are used in various applications, including
- Gas burner: For igniting gases in heating systems or industrial burners
- High-voltage testers: For tests and inspections where precise ignition is required
- Electronic ignition systems: In applications that require advanced ignition technologies.
The use of ignition transformers enables safe and efficient ignition in high-energy systems, making them indispensable in various branches of industry.
