electrical car works

By Nirmal -
Most electric cars look exactly like gas-powered cars. You will notice that an electric car lacks a tailpipe and gas tank, but the overall structure is basically the same. Once you lift up the hood, however, the difference becomes dramatic. Instead of a huge engine and all of the things you would expect to be under the hood, all you will see is an electric motor and its controller. The electric motor needs no oil, no tune-ups, and since there is no tailpipe emissions, no smog checks.

If you look under the car, and sometimes in the trunk, you will see the EVs power source: the battery pack. This battery pack is just a group of car batteries no different than the one that starts your gas-powered car. These batteries act as a "gas tank" and supply the electric motor with the energy necessary to move the vehicle. The controller acts as a regulator, and controls the amount of power received from the batteries so the motor does not burn out.

Everything else in the electric car is basically the same as its gas-powered equivalent: transmission, brakes, air conditioning, and airbags. In fact, many newer EVs actually have a single battery under the hood in addition to the battery pack. This solitary battery is constantly recharged by the main pack and it powers all of the electronic devices in the car, just like the battery in a gas-powered car.

If you are planning on getting your own electric car, or building one in our EV Builder, there are a few things you should know about each component of an EV:

First of all, there are three major types of electric motors in EVs today: DC Brushless, AC Induction, and the Permanent Magnet motor. Each has its advantages and disadvantages. The DC Brushless will offer the highest top speed, but the lowest acceleration. The AC Induction motor has the highest acceleration and an average top speed, but also has a higher price tag. The Permanent Magnet motor falls right in between the other two in both categories.

As far as batteries, Lead Acid are the most popular and the chea

The Difference between single phase and three phase system?

By Nirmal -
Phase is the differnce between waves, through which the current flows. 1 phase consists of 3 wires , 1 phase 1 neutral and 1 stay wire. 3 phase consists of 5 wires , 3 phases(R, Y, B), 1 neutral and 1 stay wire. In most of the transformers 3 phases are mostly used except the road side transformers because the voltage of 3 phase is 440v. In domestic appliances 1 phase is used because the voltage required is 230v 1. Single phase voltage is compare then three phase voltage is very low for ex- 1 phase 240v < 3 phase 440v. 2. Three phase can make rotating magnatic field but single phase can not make rotating magnatic field. 3. In three phase is phase sequence but single phase is not phase sequence.

Indoor 1. Only dry type transformer shall be installed inside residential./ commercial buildings. While using oil filled transformers certain steps are there to be followed: a. it must be installed OUTDOOR only. b.Easy access of fire station vehichles. c.the transformer room/building must be 1.5 mtr away from the residence/commercial building d. the substation must be weather proof, walls must have minimum thickness of 230mm of thick RCC, Fire resistant wall must be there. e. outside corporation area minimum distance between transformer and substation must be 6m. 2. dry type transformer must be installed above ground floor. 3.ABSF/VCB ust be provided at primary side. 4. Minimum cable size at primary must be 150sq.mm XLPE (aluminium) or 70 sq.mm XLPE (Aluminium) if backup fuse is provided. 5.Oil filled TRFR must be segregated from HT and MV switchgear. 6.oil drainage facility/soak pits must be provided for oil filled transformers if oil quantity is above 2000 litres.

Electrical phenomena in nature

Electricity is not a human invention, and may be observed in several forms in nature, a prominent manifestation of which is lightning. Many interactions familiar at the macroscopic level, such as touch, friction or chemical bonding, are due to interactions between electric fields on the atomic scale. The Earth's magnetic field is thought to arise from a natural dynamo of circulating currents in the planet's core. Certain crystals, such as quartz, or even sugar, generate a potential difference across their faces when subjected to external pressure. This phenomenon is known as piezoelectricity, from the Greek piezein (πιέζειν), meaning to press, and was discovered in 1880 by Pierre and Jacques Curie. The effect is reciprocal, and when a piezoelectric material is subjected to an electric field, a small change in physical dimensions take place. Some organisms, such as sharks, are able to detect and respond to changes in electric fields, an ability known as electroreception, while o
