Thermoelectric Self-contained Current Source The thermoelectric self-contained current source (AITT – 500G) is intended for self-contained power supply of electricity consumers, and has parameters compatible with characteristics of the specific assembly. Electrical energy is generated by a thermoelectric generator with thermal energy conversion. Consumers of electrical energy are cathodic protection systems of main gas pipelines, technological systems, field gathering systems and gas treatment and etc. The primary energy source for AITT – 500G is natural gas, flowing to the assembly from high pressure main gas pipeline ~ 100 atm. The AITT – 500G is a product of many repeated cyclical applications, which is repairable and rebuildable. The assembly fits in protection container in vandal-proof protection with a ventilation system and a fume-collecting chimney.
