Generator Synchronization

Most of the electricity consumed today is produced by three phase synchronousĀ  generator.Since a huge amount of electricity is consumed every day,AC power networks are generally made up of a large number of synchronous generator all operating in the same frequency.

When the power demand increase,additional generator are connected to the AC power network.Before connecting a three phase synchronous generator to an AC power network,the following conditions are to be observed :-

Troubleshooting method

When motor or machine / equipment not function properly,we must perform troubleshooting task to rectify the problem.It easy if we have a lot experience.

But…Dont worry,I will explain detail step by step how to troubleshooting when it not in good condition.

Firstly,before we start the troubleshooting task…the important thing is we must calm down and relax.Dont panic.We must calm to ensure we can thinks normal and can get the better idea for rectify the problem.Below is my step when perform troubleshooting task :

Electric Motor starter method

Basically motor starter designed for asynchronous motors or induction motor is a mechanismĀ  to start and stop the motor operation.It also provides over current,overload and short circuit protection during operation.

The main task is the starter motor to reduce motor starting currents,High inrush current and prevent the motor from operating when suddenly the power supply to be connected.It is for safety and to avoid serious damage of equipment or person.

Motor starter also capable to controlling the forward reverse rotation, speed motor, braking and various other duties as appropriate.In industry,motor starter very common used to control of equipments and application using electric motor for production or any process. read more

Electrical Work Practices

Working On or Near Electrical Conductors or Circuit Parts

Safety-related work practices shall be used to safeguard employees from injury while they are working on or near exposed electric conductors or circuit parts that are or can become energized.

The specific safety-related work practice shall be consistent with the nature and extent of the associated electric hazards.

Live parts to which an employee might be exposed shall be put into an electrically safe work condition before an employee works on or near them, unless the employer can demonstrate that de-energizing introduces additional or increased hazards or is infeasible due to equipment design or operational limitation.

An electrically safe work condition shall be achieved when performed in accordance with the procedures and verified by the following process:- read more
