Ignition transformers for main gas turbine typologies

Alta Industries manufactures two classes of Ignition Exciter (Capacitive and Inductive configuration) for main gas turbine typologies.

Both the Ignition Exciter are configurable in any safety normative like:

- "EEx-d" Aluminium anti- deflagration case

- "IP55" Stainless steel sealed packing

- NEMA 7 NEMA 7 USA normative compliance

- ATEX ATEX European normative compliance

Herein are listed the main characteristics of the two classes of Ignition Exciter:
