PCEL-4302 ELECTRICAL MACHINES-II

LECTURE NOTES ON ELECTRICAL MACHINES-II Fig.3.2: The effects of armature reaction in a salient-pole synchronous generator. The rotor magnetic field induces a voltage in the stator which becomes maximum in the conductors directly under the pole faces (Fig.3.2.a). When a lagging load is connected to the

VOLTAGE FLUCTUATIONS IN THE ELECTRIC SUPPLY …

voltage fluctuations are of significant magnitude. Voltage fluctuations are caused when loads draw currents having significant sudden or periodic variations. The fluctuating current that is drawn from the supply causes additional voltage drops in the power system leading to fluctuations in the supply voltage.

electric power. If the power supply is interrupted, flow conveyance is discontinued and can result in flooding upstream of the lift station, It can also interrupt the normal operation of the downstream wastewater conveyance and treatment facilities. This limitation is typically addressed by providing an emergency power supply.
