An insulation tester has been introduced to help test equipment for electrical utilities, industrial applications, data/ telecommunications and electrical contractors. Why do we test insulation over time? When insulation breaks down, it degrades for many reasons. If insulation is compromised, injury or even the danger of fire equipment failure and lost production time are possible.


What causes the insulation to break down? It may happen when electrical stress, too much voltage or even too little in a particular application can cause the insulation to crack for a breakdown.


What will an insulation tester tell us? When we start thinking about replacing the cable. The cable links current when it gets to an unsafe point. Cable issues will lead to current leakage, affecting the device's performance. Conversely, an insulation tester will help us predict when the cable needs replacing. Knowing this information lets us ensure we have the parts to repair or replace. To have a maintenance schedule as opposed to experiencing a catastrophic failure.


The British Standard Tester EI insulation tester models (EI-91 / 92 / 93) can perform insulation tests (IR test Voltage range 50V to 2500V) to assure the insulation resistance (0.05MΩ to 20GΩ) for your equipment safety. They are suitable and commonly used in various applications: EI-91 Telecommunication & wiring contracting, EI-92 industries & home appliances and EI-93 Motor manufacturer & production factories.
