How to Choose a Perfect Insulation Tester?

Choosing the right insulation tester to get the job done perfectly is quite interesting. With so many models in the market, people often get confused about picking the perfect one. So, how would you choose the best insulation tester? To figure out the answer, it is important to understand which type of testing is crucial for you. 

Examine good insulation versus poor insulation. The good insulation has high resistance while the poor have relatively low resistance. An imperfection in the insulation can cause electricity escape that can be detrimental to electrical circuits and machinery. Thus, you need to get the one that is ideal for your application. 

Check the tips mentioned below that can help you in choosing a perfect insulation tester.

Voltage Range: Voltage requirement is always the first to determine when selecting an insulation tester. These devices are high-voltage dc instruments and high voltage is necessary to pull enough current that can be measured. If you need to test on a wide range of equipment, you would require multiple voltage capacity. 

Measure the Range: Measuring current is another factor that needs to be taken care of. Look whether you are measuring leakage current or polarization current. Leakage current can be recognized by using an insulation tester and then you can calculate the amount of contamination that is in the insulation. To obtain the leakage current, you can use the spot reading. Apply the test voltage to the component under test then take a resistance reading after 60 seconds. In this way, you can determine the leakage current through the insulation. 

Testers with extended range can measure the actual reading, thereby establishing a long timeline. So, choose an insulation tester according to your needs. 

Digital or Analog Display: An analog display of a pointer or travel can display an experienced operator valuable information. It is important to check whether the pointer is running smoothly or it is just waving in between. These details are difficult to identify on an electronic display. 

On the other hand, when the pointee travel stops, it is the responsibility of the operator to note down the readings from the scale that increases the manual errors. It can be removed with a digital model because these models provide an exact reading that can be noted down easily. 

There are some testers that offer both digital accuracy and a moving indicator that combines the advantages of both display types.

Experience Level: The level of personal experience with insulation testers is also an important factor to consider. If you are experienced and have a firm grasp on interpreting readings then any tester may be suitable for you. For those who are less experienced, limited functions are recommended along with some sort of on-the-job training on insulation resistance testing.

These are some simple tips that can help choose a perfect insulation tester. Once, the prime considerations have been determined, you can filter these insulators depending on their prices. In this way, you can select specific models based on their performance and cost.
