The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.

Cutting out damaged coils from large, low-speed machines

An emergency repair to keep your customer operating with minimal disruption

Historically, one emergency repair used for large, low-speed machines (motors as well as generators) was to remove the damaged/failed coils from the circuit. Cutting out a single damaged coil permitted the machine to be quickly returned to service with minimal disruption.

As long as some basic principles are followed, this method can be safely used. It is still popular with operators of large, low-speed synchronous ma­chines. One common application for such machines is hydro power stations. There are many old hydro generators operating with a dozen or more coils bypassed. The underlying goal when cutting out coils is to minimize the negative side effects and keep coil groups intact for future removal.

WARNING: This procedure is not recommended for 2-pole machines. The odds of success are slim.
