As an increasing number of devices get connected to the cyberspace, we are embarking on a new journey towards creating a fast-paced industry called the Internet of Things (IoT). In 2015, over 15.4 billion devices were connected to the internet, and the Information Handling Services (IHS) predicts that this number will go up to 30.7 billion by 2020. According to General Electric, IoT will add $10 to $15 trillion to the worldwide GDP growth by 2030.Thus, it is time for companies to think about the long-term implications of IoT on their businesses.The Internet of Things refers to a connected network of devices with an on/off switch to the internet. These devices can interact with the environment and other devices that are a part of the same network. Read More
Any sort of work which includes an exposure to electrical circuits and equipment involves its own set of risks. Particularly, electricians are exposed to these hazards on a regular basis. We commonly know that electric shock is the only danger electricians are exposed to, but little do we know that electric arc explosion is an equally perilous threat, which can generate blistering heat called arc flash that can cause lethal injuries. read more
It’s not uncommon for home and business owners to contact an electrician when they are having electrical problems in their home. From electrical sockets causing shortages to replacing old light fixtures, there are a number of issues that people may need to be addressed.
Though each problem may be different, there are some common concerns that electricians and anyone who assists them must be familiar with and that is taking the appropriate safety measure to avoid unnecessary risks and injuries. That being said, here’s several safety precautions that must be taken to keep everyone safe. Read More
As we known,electric motor is an electrical equipment that convert from electrical source to mechanical energy and create rotating force.For Electrician or Electrical Engineer,to choose a right motor specification for installation or equipment is important and it’s critical decision have made.
We must know all about electric motor specifications to suit for our application.All important parameters or specifications that we need for our application design must suitable with electric motor that we want to install to avoid any damage or failure during operation.
This time I would like to share about Electric Motor Specification that we must understand before we select or purchase new motor for our installation or project.How we can found about electric motor specification? Read More
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.

As we know,motors is a common used for rotating equipment to make domestic and industrial operation more easier.In general,electric motor is reliable machine with minor maintenance require.But to ensure electric motors have a more life span and service life,we must perform periodical inspection and service and schedule it with proper arrangement.
With periodical inspection and services, we can reduce motor failure and minimize downtime for operation.Record all data and finding during inspection for our referral and also can perform diagnostic report.Normally periodical inspection for motor should be such as motor base condition,shaft alignment,bearing condition,motor temperature and belt tension or coupling position. read more
As we known when working on electrical installations, safety matter is our priority.Every step we need to consider about hazards when perform electrical works.
Only competent electrician can work on electrical installation or live condition according to relevant industrial safety standards.Common industrial safety standard for electrical works such as VDE 0105 for Germany, and international standards for EN 50110 or IEC 60364.
For electrician,they need to special tools which have been tested and qualified with electrical standard.Hand tools also must suitable and followed the electrical standard IEC 60900 and it has specified worldwide requirements for tools for electrical live condition.
