Testing the integrity of insulation in electrical systems is crucial for maintaining safety, efficiency and preventing equipment failure. In order to test the resistance of wire insulation to leakages, insulation testers are used. Some of the best testers on the market are from the world-leading brand, Hioki.
Why is insulation testing important?
Insulation testing is required in many electrical applications across almost all industries. In very simple terms, insulation resistance testing is conducted to locate shorts in cables and other electrical equipment. Most wires are insulated, which is done to ensure all the current sent through a wire reaches its destination. However, leakages can still occur, which causes equipment faults, lower power output or even safety risks.
Different types of insulation testers
There are several insulation testing units available in the Hioki range. The two major groups are analogue and digital testers, however, in each category, there are some variations.
These units are used to measure insulation resistance on photovoltaic systems. They can be used even while generating solar power, meaning the measurement won’t be affected by solar energy being generated.
Used to decrease the work time associated with field insulation testing, these units deliver pass or fail readings in 0.3 seconds and make it easy to create reports. They measure across 5 ranges, from 50V to 1000v.
Primarily used for high-voltage applications, such as testing transformers, cables and motors. These units are 5-range and measure up to 5kV. They also provide up to 10TΩ of insulated resistance testing.
Analogue insulation testers – single range
There are a few different types of single range analogue insulation testers in the Hioki range. These units are primarily designed for smaller applications and feature a capacity of up to 500V/1000MΩ.
Choosing the right insulation tester
When looking for the right Hioki insulation resistance tester for your needs, you should consider a few things you need to consider. The following questions will help you determine which testing unit is right for you.
- What types of equipment will you be testing?
- Where will you be using the testing unit?
- What are the voltage requirements?
- How experienced and knowledgeable is the person using the unit?
- What resistance range do you need to check?
Why choose Hioki?
There are plenty of reasons to choose Hioki insulation testers. Firstly, the range is diverse. You’ll find units suited to small testing jobs, all the way through to high-voltage applications. Hioki testing units feature bright LED displays, making it easy to get the readings you need in all conditions. They’re also an all-in-one design and come built into rugged cases. So, if you’re out in the field and need equipment that’s built tough, Hioki is a perfect choice.
Hioki testing units are designed with ease of operation in mind, too. With just the press of a button, you can get instant readings, or leave the unit for continuous monitoring.
