About High Voltage Insulation Testers

All electrical insulation is susceptible to degradation over a time period. At the start of its service life the insulation applied to an electrical system - whether its a common appliance such as a kettle or a high powered device like a transformer - should be strong enough to make leakage current non existent or negligible and ensure that the electrical installation/appliance can be used safely.

However insulation will degrade over time leading to more potential leakage current. As such the system becomes less and less safe over a time period, and this is exactly why insulation resistance tests must be regularly carried out in order to ensure that the resistance of the insulation is sufficiently high.

We have a range of different insulation testers depending upon the application they are to be used in.
