What is TOD tariff?
Consumption varies throughout the day (and/or season) so usage pattern varies accordingly and hence demand. In certain timing of the day, electricity demand attains its peak. Normally Indian utility experiences morning peak and evening peak. The demand-supply
Energy audit schemes
Big industries and utilities should be mandated to carry out an energy audit as its identifier the areas of losses and measures to reduce. Incentives should be awarded to utilities as well as consumers who are being
Bill collection facility
A number of payment cells for paying electricity bill should be increased with the development of the areas. Increase in dropbox facilities is also an option for payment collections. E-Payments facility: Options for E-payment are suitable for
Amorphous iron
In the context of energy efficiency in the transformer, amorphous metal core proves advantageous. Amorphous metal is produced by rapid cooling of the molten metal alloy. Amorphous metal is gaining more attention in the nation as well
Energy efficient transformer
Power utility can achieve energy conservation in transmission and distributions system by reducing their efficiency. Distributions system is the key area identified to improve the efficiency and hence health of the financial state of the power sector.
Compensating reactive power flow
Unity or in nearer to unity power factor is one of the most desirable for a consumer in order to minimize penalties in order to minimize penalties for low power factor. Due to poor power factor, size
Transmission and distributions losses in maharashtra
If we observe T&D losses in the state of Maharashtra there is a decrement in the total % every year from 2003-04. Though the % improvement does not seem significant, T&D losses have been improved from 34
What is cast resign ?
In these units, coils are enveloped in resign by process of moulding. The transformer coils are solidly cast in resin under a vacuum in a mould. The manufacture ring process in such that winding is locked in
What is flexibility
The possibility of increase or decrease of demand in future can never be ignored in power system. Provision of connections of the parallel transformer to meet the increased demand keeps the system flexible. Installation of the signal
Measurement of electrical
Electrical load parameter, as well as machine side mechanical parameters, are measured for the purpose of motors study. Measurement on selected motors is carried out to for electrical parameters such as: Voltages Load current Power factor Power
