Transformer Humming Noise Explained - TestG

For average expected sound levels of dry-type transformers, refer to NEMA ST-20. Dry type transformers are most frequently applied inside buildings. In a room with walls of low sound absorption coefficient, the sound from the transformer will reflect back and forth between walls resulting in a build-up of sound level in the room.

Steam car - Wikiped

A steam car is a car (automobile) propelled by a steam engine. A steam engine is an external combustion engine (ECE) in which the fuel is combusted outside of the engine, unlike an internal combustion engine (ICE) in which fuel is combusted inside the engine. ECEs have a lower thermal efficiency, but carbon monoxide production is more readily regulated. ...

It’s pretty safe to assume that this noise is caused by either kettling or trapped air inside the central heating system. First, try to bleed your radiators to remove the air.. This is a very easy process and doesn’t need an engineer call-out, but don’t forget to check and adjust your boiler's pressure afterwards.. If you’ve bled your radiators but the noise persists, kettling could be ...
