5 Electrical Cabling Terms You Need To Know

Electrical cabling, and its associated jargon, can make for a confusing or overwhelming experience. Yet making a mistake when dealing with electrical cabling and its accessories, could stop you wiring project dead in its tracts, or even prove fatal.

Here we take a look at the most important electrical cabling terms you need to know, whether you are wiring yourself or talking to an electrician. Read More

Motor Specifications – Voltage,Ampere and Frequency

These parameters are important to clarify our application design from voltage value,phases,full load ampere, overload setting and frequency setting if using Variable Speed Drive.

As an electrician,we must fully understand what is mean by voltage, ampere and frequency to ensure our application safe and working properly.

Ok…let we start our discussion and explanation about Voltage, Ampere and Frequency on Electric Motor Nameplate.

RATED VOLTAGE (VOLT)

What is Rated Voltage?For simple understanding, rated voltage is manufacturer design for suitable operated voltage value with optimal performance.We can refer the motor voltage and phases on the nameplate also can decide either voltage/phases is available in our installation or not.Every country have different value of voltage.Please make sure your motor are followed standard country voltage.

How to use three phase motor in single phase power supply

This time,I would like to share some important knowledge that I used it when faced emergency or critical situation.What are you doing if have only three phase motor and single phase power supply available?

How to use three phase motor in single phase power supply?Actually three phase motor can operate in single phase power supply  with the help of a permanent CAPACITOR.This small thing (capacitor) very helpful to make three phase motor running in single phase power supply.

As per our last discussion about three phase motor,normally it’s have two(2) common winding connection ,STAR or DELTA connection.In this post,I explained how to wiring the capacitor in three phase motor,how to change motor rotation,how to estimate value of capacitance and selection of suitable capacitor.

Electrical Cable/Wire General Requirement

This topics always discussed among of electrician personnel that involved on new installation or electrical projects.If they miss calculated or choose a wrong size for the conductor/wires,it’s can cause a big disaster when that installation failure.

Electrical cable/wire is a important things that we must consider with calculation and detail discussion to avoid any mistaken during design and installation.We must take a serious action to get a good result.

I would like to shared some general requirement for electrical cable/wire for new electrical installation or projects that we must consider during design review.I hope this can make a guide line for the best result in your installation or projects. read more

Current rating

Why current rating value is so important for cable/wire sizing?This time i want share some information about cable rating.It look like simple value but it give the big impact when we not do the proper sizing to the cable for our application.

If during cable sizing calculation not done in proper way,it can cause a serious damage for electric cable,equipment and human.It also can cause the waste of money when it over sizing and increase the budget for reworks.

That it current rating play a important role during cable sizing for electrical wiring job scopes.We can choose the right cable size read more

Distribution substations

For electrical power distribution,substation is the one important component to serve,distributing and regulated an electricity to building,factory or private living area.

Normally substations have the several required equipment such as power transformers and the voltage-regulating device for converting the high incoming sub-transmission voltages to low voltage primary system and ensure it in specified voltage tolerances.

The others basic equipment in substations includes circuit breakers, switches, bus bars, shunt coil reactor, power factor correction capacitors, lightning arresters, read more

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
