## Two Point Method

This is another alternative method for earthing resistance measurement when excellent ground is already available.When we want to perform the measurement for earthing resistance in the compact room or tight area and want to put the two(2) auxiliary rodÂ  may be a problem.

So..to solve this problem,we can use the two point method measurement.This measurement concept is two point into the ground in series technique used to the reading obtained.

The earth surface or other ground must be very low in resistance so that it will be negligible in the final measurement. The lead resistances will also be measured and should be deducted from the final measurement. read more

## Foot Protection

Employees working in areas where there are electrical hazards shall be provided with, and shall use, protective equipment that is designed and constructed for the specific part of the body to be protected and for the work to be performed.

For electrical or maintenance persons,safety shoes is the one of important PPE ( personal protective equipment ) to avoid from serious injury such as electric shock.Please ensure our safety shoes suitable with electrical works because not all safety shoes have a ELECTRICAL HAZARD PROTECTION ( EH ).

Where insulated safety shoes is used as protection against step and touch potential, dielectric overshoes shall be required.It also protect from impact, compression, and puncture are the most common types of foot injury. read more

## Direct Current ( DC )

### What is a direct current (DC) ?

Direct current (DC) is an electric current that flows continuously in one direction only. This is the type of electrical current is supplied if the voltaic cell. As long as the polarity of the voltage at the bases voltaic cell is fixed and does not reverse, the voltaic cell can be referred to as a source of direct voltage

## Electric shock first aid

### How much current quantity to our body can stand?

To answer this question,we back to OHMS LAW of electrical resistance.In a case of a shock ,the amount of current through the body is determined by the following formula :-

I = V / R

I = Current

V = Voltage

R = Resistance of the body

## What is Electric?

### Electrical definition.

WHAT IS ELECTRIC ? This is a question often asked by people around the world for those who wish to enter the electrical field, they should understand basic electricity.It is very important because electricity can not be seen with the naked eye.we only know about the theory of electricity. in the field of electrical “knowledge is power ” to ensure that we and electrical equipment in a secure and functioning well.We must have a strong basic of electrical..

Ok…here from my simple understanding,Basic of Electric is a electron ( negative charge ) always around a proton (positive charge) and neutron caused by the force of attraction between protons and electrons
