could you please explain how to synchronize an incoming alternator with running system.I heard about ''dark lamp" or 'bright' method.But what actually the process is?
http://en.wikipedia.org/wiki/Alternator_synchronization"...three light bulbs were connected between the generator terminals and the system terminals (or more generally, to the terminals of instrument transformers connected to generator and system). As the generator speed changes, the lights will rise and fall in intensity at a rate proportional to the difference between generator frequency and system frequency.
The purpose of synchronizing alternators is to ensure that two or more generators are running in parallel and producing the same frequency and voltage. This is necessary in power systems to prevent power outages and damage to electrical equipment.
The synchronization procedure involves the following steps:
There are three main methods of synchronizing alternators:
If alternators are not properly synchronized, it can lead to a number of issues, including:
Some precautions that should be taken during the synchronization procedure include:
