Precautions to take in rainy season.

Image
Indoor Safety- Periodically test the electrical installation for insulation strength and replace if required. Replace damaged electrical components like switches, plug sockets etc., immediately when noticed. Use only ISI marked electrical appliances, cables and wires. Use 30 mA ELCB the "LIFE SAVER" at the main supply point. Get electrical work done only by qualified licensed electrical contractors. Install switches and plug sockets at an inaccessible height and away from children. Do not use electrical appliances that have been wet. Make sure that there is easy access to switch off the supply source quickly in case of an emergency.  Do not fix a nail on the wall where concealed PVC conduit wiring has been done.  Outdoor safety- Avoid fallen electricity poles and power lines or anything in contact with these. Do not touch water or anything in contact with water near where there is a downed power line. Do not try to free somebody who is in contact with an electrical power line...

Types of industrial lighting fixtures

Image
Industrial lighting fixtures come in a variety of shapes and sizes, each designed for a specific purpose. Some fixtures are used to provide general illumination, while others are used for more specialized purposes, such as task lighting or accent lighting.  With so many different types of fixtures available, it can be difficult to know which one is right for your needs.  Five of the most common types of industrial lighting fixtures include: Fluorescent lighting High Intensity Discharge lighting Incandescent lighting LED Metal halide Fluorescent light  – Fluorescent light fixtures produce artificial lighting using fluorescent gas. These fixtures work well in office and industrial settings because they are efficient and have a long lifespan. Here’s how they work.  Fluorescent lights use an electrical current to ionize gas inside the bulb. This process emits ultraviolet light, which then interacts with the phosphorous coating on the inside of the bulb to create visible ...

Why it is important to hire experienced Electricians.

Image
If you are not an expert about things like electrical panels, wires, outlets, and all the other electrical parts, you should not attempt to make electrical repairs your own. Hiring the services of a professional electrician is smart when it concerns the safety of your family and property. The reasons why you should hire a professional Electricians:   Safety for all Working with electricity is not a task that can be safely handled by an untrained and unlicensed person.  It is better to let a licensed and experienced electrician handle all the electrical systems of your home.  Cost-effective An electrical project handled unprofessionally will mean costly mistakes not only in materials but to life and limb as well. Hiring a professional electrician avoids this risk, saving you money with the quick resolution. The proper way of doing the job An electrical job is not a hit-and-miss project. It has to be done right all the time and every time to guard the ...

Why transformer Ratings are in KVA?

Image
  All electrical devices are rated based on the maximum power it can consumes, generates or transfer. Transformers are rated in kVA or VA . Transformers are an energy transfer device that transfers power from the primary side to the secondary side without changing frequency. Why transformers are rated in kVA and why not it is rated in kW like heater, motor and other electrical equipments? 1- Copper loss in transformer depends on the current and the iron loss depends upon the voltage of the transformer. Total losses in a transformer depend upon volt-ampere (VA) only and not on the power factor of the load.This is the reason transformer is rated in KVA and not in KW 2- Transformers are manufactured without considering the load being connected. So any kind of electrical load can be connected it may be resistive, capacitive, inductive or combination loads. If the transformer is rated in KW, there may be confusions regarding the type of load being connected. That is why the transformer ...

Causes of Solar panel Degradation

Image
The degradation of solar panels is not caused by a single phenomenon, but by several degradation factors affecting photovoltaic modules, but mainly due to the aging of the use time. Other causes of solar panel degradation include aging, light induced degradation (LID), potential induced degradation (PID) and backplane failure. 1- Aging caused by service time Aging is the main degradation factor affecting the operating life of PV modules. This degradation is due to the direct consequence of years of exposure of modules to rainfall, snowfall, extreme temperatures, hail, dust and other external factors. When photovoltaic modules are exposed to the above external factors, they will begin to decay and reduce their efficiency over time. This is due to the corrosion of the solar panel frame, the delamination of glass and backplane and the loss of the performance of photovoltaic materials, all of which lead to the degradation of photovoltaic modules by 0.5% per year on average. The solar modul...

Different types of Transformer Faults

Image
A transformer is a device which helps with the transmission of electrical power, it is a static device without any rotating part and is totally enclosed. So the transformer plays a major role in the electrical distribution so the protection of transformers is an important process. The transformer must be protected from faults in order to do effective power distribution. What are the types of transformer faults 1-Over heating Over-heating is caused due to sustained overloads, short circuits and in case of failure of the cooling system, Overexcitation if a transformer is operated at its maximum potential like high frequency or in high voltage the core will get excited. Protection - Resistance temperature indicator can be used near the winding, Thermal overload and temperature relays can be used. Bridge circuits can be used when the bridge is unbalanced more than the permissible duration circuit breaker trips. 2-Winding faults The winding faults are internal faults, over-heating or mechan...

Why Aluminium prefered in transmission line than Copper?

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...
