Generator Synchronization

A stationary generator must not be connected to live Busbars because the induced EMF is zero at standstill resulting in a short circuit. The Synchronisation procedure and the equipment for checking it are the same whether one alternator is to be connected in parallel with another alternator, or an alternator is to be connected to …

Hunting in a Synchronous Motor

The phenomenon of oscillation of the rotor about its final equilibrium position is called Hunting. On the sudden application of load, the rotor search for its new equilibrium position, and this process is known as Hunting. The Hunting process occurs in a synchronous motor as well as in synchronous generators if an abrupt change in …

V Curve of a Synchronous Motor

V curve is a plot of the stator current versus field current for different constant loads. The Graph plotted between the armature current Ia and field current If at no load the curve is obtained known as V Curve. Since the shape of these curves is similar to the letter “V”, thus they are called …

Starting of a Synchronous Motor

A synchronous motor is a device that converts the AC into mechanical work at synchronous speed. The starting of the Synchronous Motor does not take place on its own. This means that the Synchronous Motor is not Self Starting. It can be started by the following methods given below: Starting with the help of an …
