Types of generator

Generator is the important power supply equipment to generated electricity.Without electricity,we cannot operated machinery,equipment,lighting,computer and others device for our living.

For general power supply,power distributor normally used the high capacity of generator to supply the electricity to the consumer.It different size for backup power supply that used for hospital,server room,critical equipment or important area.

I want share some information about types of generator and basic operation.Generators are generally classified in accordance with speed and construction.We can categories the generator with following types. read more

Drawing for electrical installation

For electrical installation,the main factor to completed the task with quality and in time,we must make sure the detail and comprehensive drawing are provided.

These drawing is important to show in clear view about position of electrical equipment,access for electrical cable,switch and socket location and others important item.

The drawings scale are based upon the architect’s site plan of the building completed with electrical symbol to identified the electrical equipment for the real site to show the actual placed for installation works. read more

Thermal model protection for Soft starter

Motor protection is the one of important criteria that we must consider when design the application to avoid serious damage or injury.

Normally we used thermal overload relay to protect electric motor from overload current problem.But if we used soft starter to driven our motor application,the suitable types of protection is using the motor thermal model.

This types provide more precise protection for electric motor and it more accurate and efficient.It only available for high end motor protection relay for conventional starter. read more

Types of soft starter

Soft Starter is the common application for electric motor control driven for industry.It efficient motor control and the application is user friendly.

Soft starter now more advance technologies and can replaced conventional motor starter such as star delta starter,auto transformer or Direct Online starter.It already built in the motor control system and easy to install and wiring to our application.

This time i want share some information about types of soft starter.These types is different because it depend on application and system design.Before we install a new soft starter to our application,we need to understand basic types of soft starter. read more

Escape and emergency lighting

In accordance with the Fire Precautions Act 1971 and the Health and Safety at Work Act 1974, BS EN 1838 : 1999 Code of practice for the emergency lighting of premises must followed with minimum standards to achieve the safety target.

It is important matter for safety precaution when emergency happen such as fire,explosive,electrical disaster or etc.This system provide the solution for escape to the assembly point in safety and proper ways.

For each country it have their own Act,regulation and code of practice.Basically it quite similar and have additional items depend on their application and suitable with their country. read more

Controller method for automatic voltage regulator

Basically automatic voltage regulator for generator have a 2 mode selection.It is with full automatic function and manual function.

I already discuss about AVR function and basic operation in my last post.Please refer to basic of automatic voltage regulator.i hope it can make a clear view and understanding about AVR function in generator.

This time i want share some information about controller method that commonly used for AVR for generator.For latest design of AVR,manufacture put a two(2) selection for AVR controller mode.It is Automatic and Manual mode. read more

method for braking electric motor

On my last post, I’m already explained about braking system for electric motor.It about a introduction for braking system for electric motor.

This time i want share some information about two common method that used around the world for braking electric motor for any application,equipment or machinery system.

For this two method for braking electric motor system are d.c injection and plugging is suitable application to stop a drive efficiently depend on our system and design. read more
