The ramp function gradually increases voltage up to a selected level while graphing current vs. voltage. Graphs can then be downloaded, or streamed real time (Must purchase optional software). Graphs can then be compared to example curves in IEEE 95-2002 to reveal a variety of faults difficult to detect otherwise. Small defects can be easily detected without risking the sudden large voltage increments produced by a Step Voltage test. Monitoring the developing graph during test enables the operator to terminate prior to breakdown, thereby reducing the possibility of damage to already flawed insulation. This unit is particularly informative on polyester, asphalt and epoxy-mica insulations. They can also test voltage suppression devices. Please check our Huge Inventory with savings of up to 8.
