Rely On Protec For All Your Insulation Resistance Testing Needs

To understand insulation testing you don’t need to go into the mathematics of electricity, but one simple equation – Ohm’s law – can be very helpful in appreciating many aspects.

The purpose of insulation around a conductor is much like that of a pipe carrying water, and Ohm’s law of electricity can be more easily understood by a comparison with water flow.  The pressure of water from a pump causes flow along the pipe. If the pipe was to spring a leak, loss of water pressure would occur and water would be wasted.

With electricity, voltage is like the pump pressure, causing electricity to flow along the copper wire. As in a water pipe, there is some resistance to flow, but it is much less along the wire than it is through the insulation.

For all your insulation testing needs, rely on Protec. We offer equipment from all of the premiere manufacturers for rent, lease or purchase.
