High voltage detector

01/04/2011 by Leave a Comment

High voltage detector or indicator is the one of  important tool when perform the task in high voltage.It can determine if electrical line is live or not.The main purpose is to ensure we perform the job in a safety condition.

Around the world,many accident happened for electrical shock came from misidentified the electric line either it live or dead.Maintenance or electrical  person must double verify and confirm the electrical line status before do their job.

In the market now,we can choose many brand and types of high voltage ( HT ) detector.We must selected the suitable device depend on our application and system.

If we not sure how to used it,please request the supplier or technical expert to do a briefing and practical training how to used a high voltage detector.It very important because if not it can cause a serious damage for human and application. read more

How to use a clamp on meter?

15/02/2011 by Leave a Comment

In electrical field,current (ampere) is very important value.It very useful to sizing the circuit breaker,sizing the electric cable,for troubleshooting guideline and many more.Without ampere value,we cannot get the best result for sizing or design.

How we can get a current value?We can use the ammeter or clamp on meter to measure the current value.If you remember in last post AC DIGITAL CLAMP ON METER,ampere must be measure in series circuit to get the value.Now for easy current measurement job,we use a clamp on meter.

I explain detail on my video how to use the clamp on meter.The important thing is we must safety first.Make sure the distance of  live conductor must in safe range.always beware when u perform the measurement job using the clamp on meter. 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

Insulation Resistance Tester

21/09/2010 by 2 Comments

Why we need to perform insulation resistance tester?This test is strongly recommended to prevent electrical shock for equipment,electric motor or electric cable.We also can determine any abnormal condition or leakage before installation and can rectify the problem.

Insulation resistance tester is the one of  important equipment/meter for determining the resistance of the insulation in motor winding, transformers winding or electrical cable in good condition or not.

This tool facilitates off to make an informed decision about the condition of equipments can be used again, whether or not based on the value of reading difficulties.According to standard IEEE 43: IR test minimum value of the electric motor is a 1 Mega Ohm ( 1 MΩ ) read more

Description Of The Multimeter

05/09/2010 by 5 Comments

What is a multimeter?

Before we know how to use a multimeter,we must understand a safety information about multimeter.

To avoid possible electric shock or personal injury,PLEASE follow these guideline

  • Do not use the meter  or test lead if they appear damage or not operating properly.
  • Always use proper terminal,switch position and range for measurements.
  • Verify the meter`s operation by measuring a known voltage.
  • Do not apply more than the rated voltage,between terminals or any terminal and earth ground.
  • Use caution with voltage above 30 VAC rms,42 VAC peak or 60 VDC.It pose a shock hazard.
  • Disconnect circuit power supply and discharge all high-voltage capacitor before testing RESISTANCE,CONTINUITY,DIODE OR CAPACITANCE.
  • Do not use the meter around explosive gas and vapor
  • When using test lead,keep your finger behind the finger guard.
  • Avoid working alone
  • Use only the replacement fuse specified.
  • Check the test lead  for continuity before use.Do not use if the reading are high or noisy. read more
