Transformer Oil Filtration

Image
Transformer Oil Transformer oil is a very important for the functional transformers and are the dielectric substance that helps in maintaining their temperature. Transformer oils are vital for the proper running and functioning of the transformers. It is one of the main asset in the electrical power industry which needs to be maintained for guaranteed uninterrupted power transmission in order to get assured revenue benefits. Transformer oil filtration: Transformers require filtered and dried oil. During its usage, the insulating oil absorbs moisture and gets polluted by sopping fibers, dirty particles, aging products, and soot. Even unused oil is not clean enough as it may have absorbed moisture from the air or may have got polluted in the barrel it was stored in. The efficiency of the oil as an insulating material is highly reduced as the moisture level increases. Hence, transformer oil filtering is an important process which eliminates solid particles, dissolved gasses, and dissolved...

Solar Panel and it's types

Image
Solar panels  are those devices which are used to absorb the sun's rays and convert them into electricity or heat .  Solar panel is actually set of photovoltaic modules, mounted on a structure supporting it. The Benefits of Solar Panels Solar panels make it possible to live off-grid. It is both a clean and a renewable source of energy. Low maintenance cost. Once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system's lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! Types of Solar Panels The solar panels can be divided into 4 types, Monocrystalline solar panels Polycrystalline solar panels Passivated Emitter and Rear Contact cells (PERC) solar panels Thin-film solar panels 1- The monocrystalline solar panels  They are also known as the single crystal panels. They are made from pure silicon crystal which is sliced into several wafers forming cells. These wa...

What is the meaning of Gross and Net metering?

Image
  What is Net metering and Gross metering? The electricity bills you receive at the home, office, or other buildings, are tracked by an electricity meter to make the acquaintance of the units of electricity you consumed. Generally, for our daily usage, we use the electricity from the power grid and from there, we’ll get the power consumed charge. But, if you have the capacity to produce electricity at your premises itself, then the mechanism of the power grid changes. Solar roof-mounted PVs has become a standard system for generating a secondary source of power for users. As electricity storage is expensive, these systems are often connected to the grid to export surplus electricity to the grid, and deficits can be imported from the grid. With the help of advanced technologies, governments, when designing the regulations for solar rooftop systems, introduced two arrangements –: Net metering Gross metering How does Net Metering work? The Net Metering policy was introduced in India, ...

Electrical Earthing

Image
  Earthing or grounding It is the process of transferring the immediate discharge of electrical energy directly to the Earth with the help of the low-resistance wire. The electrical earthing is carried out by connecting the non-current-carrying part of the equipment or the neutral part of the supply system to the ground. A safety measure devised to prevent people from getting shocked if the insulation inside electrical devices fails is called Earthing. The third pin in the plug is actually the “Earth” or “Ground” connection of the electrical appliance. The Earth, being a good conductor of electricity, acts as a convenient path for the flow of electrons that escape the insulation. Furthermore, the gigantic size of the Earth paves a path for the safe discharge of the electric charge. Why is Earthing/Grounding necessary? There are 3 mains reasons why all electric devices need to be connected to the Earth. Human Safety -  A properly earthed device doesn’t leak out any current. Thi...

Why Aluminium used in Overhead line?

Image
Overhead power line is an important part of power system.  The cost and life of transmission line primarily depend on the material used for making conductor for transmission line. The most important and much suitable material for conductor of transmission line is copper as it having high conductivity and high tensile strength, More ever it is having good ductility. Only Limitation is its cost. With the discovery of practical mass production methods for aluminum processing, the price of aluminum quickly fell, making it a more affordable choice for manufacturers and designers. It takes an aluminum wire with a diameter 1.5 times that of copper to transmit the same amount of electricity, but that wire will be three times lighter, meaning that aluminum is a more efficient material for electrical applications. High voltage overhead power lines are manufactured from aluminum to reduce weight while supplying good conductivity. Aluminum is having sufficient conductivity. More ever it is lig...
