Choose the right High Voltage Tester based on the purpose

It can be a bit daunting at times to choose the right insulation tester. There are so many models available in the market from affordable one to the costly one, from simple to complex. Thus, it becomes confusing for one to make a choice. Some of them have good insulation, while some have inadequate insulation.

And how do you find which one is good and distinguish that with a poor quality product? It’s simple, just check for the resistance. One with high resistance has good insulation while the low resistance one is poor in terms of quality. Here are a few aspects to consider before making a choice of high voltage testing equipment to make your task easy.

  • Voltage and voltage range is always the prime consideration when it comes to picking an insulation tester. It is essential to have high voltage to pull enough current. At the same time look after the measuring circuit and voltage source that should be sensitive and highly stabilized. The power source is another factor that depends on the environment, experience, and personal preference. Insulation testers supply one or many discrete test voltages depending on the model, which are committed by selectors switch.
  • Accuracy plays a very essential role when it comes to choosing the right high voltage test equipment. You shouldn’t be satisfied with the sheer digital units of plus/minus percentage. It should include some other terms such as a number of digits and LSD. Be careful when it comes to an analog statement as it can often be deceptive when listed as a percent of scale. Therefore, it is advisable that you don’t just stop at the percentage statement, but at the same time examine the other terms as well.
  • What type of tester you are going to purchase also depends on the environmental factors. Ask yourself these basic questions as in where the tester is going to be used- inside or outside? Are you going to use it in a shop or in an industrial plant? Will it be used for preventative maintenance, troubleshooting, or perhaps both? And once you decide its purpose based on the factors mentioned, you will then find it easy to decide the size and the type of tester you’re going to use.
  • The experience and knowledge you have about the high voltage cable testing equipment also play a vital role while choosing a tester. If you’re experienced enough and have a firm grasp on interpreting readings, then you can choose any tester relying upon the usage and the environment. But for the ones who are less experienced, it is recommended that you go for the simple one and the one having a limited function.

Other things to consider include Guard terminal, Voltmeter capability, and Ohm and kilo-ohm. The present generation high voltage tester manufacturers have come up with some fantastic insulation that is fully automatic, and no manual balancing is required. It also calculates the ratio error and automatically isolates the test voltage. The complete high voltage testing is done automatically and quickly.
