To keep the involvement of the people alive in the lockdown Honourable Prime Minister Shri Narendra Modi announced that on 5th April 2020 Sunday at 09:00 PM we have to shut down all electrical lamps for 09 minutes to show out the unity of the country to fight Corona Virus (COVID-19). And we will do this as a united nation INDIA. The demand is expected to reduce by about 15 GW during the nine minutes. But there are some effects of a sudden sharp fall and rise because already Industries, Railways and some Commercial loads are shut down and mostly Residential loads (Lamps, TV, AC, other home appliances, etc.) are alive, due to that power generation is reduced drastically and generation is going on at 30-35% of capacity. The power generation in India principally by Thermal power station and Hydropower station. In that operating and controlling of the hydropower station (HPS) is easy as compared to the thermal power station (TPS) i.e. HPS are easy to start and ...

The Electric bill won't give you a Fright if you remember to Turn off the light. I t is the duty of the Electricity Supply Company (MSEDCL) to notify the periodicity of billing, date of meter reading, bill date and the due date for payment in a calendar month. The Company shall issue a bill to each consumer for the electricity. The bill is prepared on the basis of meter reading. In case the meter is not provided to a consumer the company shall prepare the bill based on the procedures approved by the Regulatory Commission. Electricity Rate/Tariff: The rate at which Electrical Energy is supplied to the consumer is known as Electrical Tariff. Electrical energy is a form of energy resulting from the flow of electric charge. Energy is the ability to do work or the ability to apply force to move an object. Energy (E) = Power (P) X Time (t) Unit: Watt-Hour (i.e. kWh/MWh/GWh) Sample Bill (Source MSEDCL) HSN Code (Top Right): 27160000  The main purpose of HSN is to c...

Thevenin's Theorem: Thevenin’s Theorem is used to solve complicated electrical networks that cannot be solved by conventional methods. This theorem gives an organized approach to solve the given completed electrical network.   This theorem also gives a technique by which the fixed part of the network is replaced by an equivalent circuit. Statement:  "Thevenin’s Theorem states that a linear two-terminal bilateral circuit can be replaced by an equivalent circuit consisting of a voltage source (V Th ) and source resistance (R Th ) connected in series. This series resistance is often called Thevenin Resistance." Where V Th  is the open-circuit voltage at the terminals and R Th  is the input or equivalent resistance at the terminals when independent sources are inactive or turned off. Inactive sources, Current Sources are short-circuited and Voltage Sources are open-circuited. If the given circuit is AC then the circuit shou...
