Troubleshooting For Electronic Circuit

10/02/2011 by 3 Comments

For maintenance or electrician,troubleshooting can be a very financially rewarding and personally satisfying.The good troubleshooter has a advantage and proper understanding of electrical or electronic ,hand on skills and problem solving techniques.Troubleshooting is an art.It need creativity and passion to become the expert.

Electronic devices or equipment contain similar component in their circuit board such as transistor,diode,capacitor,resistor,ic,relay,connector,wire and etc.We must understand deeply the component characteristic,common fault for these component,and how to test and verify their condition. read more

Two Point Method

01/02/2011 by Leave a Comment

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 rod  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

Grounding resistance measurement

04/10/2010 by 2 Comments

Grounding or Earthing is the compulsory device for electrical installation.It’s the end point for electrical residue when leakage happen on electrical circuit or installation.

Good grounding can make a different of current balancing in phase during electrical leakage and Residual Current Circuit Breaker will activate if current leakage value over the sensitivity.( 10 mA,100 mA,30 mA,300 mA).

To get a good grounding,we should make sure the resistance is minimum.For the best resistance value is “0 ohm” or less than 5 ohm.That why grounding resistance measurement is important because we need to ensure our grounding is good. read more

Induction motor fault finding

03/10/2010 by 11 Comments

Induction motor is common application for domestic and industrial for machinery and production equipment.We can found electric motor in every where and should have a basic knowledge about how to troubleshooting or fault finding when we facing the motor breakdown.

If we not have any experience or not familiar with induction motor,we will face some trouble and if it’s fault finding done by un-experience person,fault finding task is very difficult and maybe can cause a serious damage or injury.It required knowledge and experience to trouble shooting and found the root cause for the problem.

So,this time i share with you`ll a basic fault finding for induction motor.Hope can be a guide for electricians.I listed some usual problem and solution for induction motor.Please refer my fault finding and recognition table. read more

Earthing Resistance Tester

24/09/2010 by 9 Comments

When we need to perform Earthing or grounding resistance measurement,the important equipment that we must have is the Earthing resistance tester.

We can found many types and brand of Earthing resistance tester in the market.It’s depend on our budget,requirement and application on actual work site.We need to ensure this device must always calibrated to get the accurate reading.

This equipment is used to measure the resistance ( ohm) of the earth.It is important to ensure that the electrical installation grounding system in accordance with the specifications and meet the earthing requirement. read more
