The 8000 Series DC Hipot Testers offer a 60 to 300 kV range in a convenient cascade design. These systems are air insulated, with each module individually capable of producing 60 kV at 16 mA. The standard power rating is 2 kW. Low leakage measurement, even with fluctuating line voltage, is possible with the 1%-line regulator. The design also offers reversible polarity.

This modular (expandable) construction favors the use of these portable testers in situations formerly requiring large mobile units. For example, when field testing, each technician can be equipped with one controller and as many modules as routine tests require. Then, for any non-routine higher voltage tests, additional modules may be assembled at the test site.

For example, a 240 kV test requires one controller and four modules. Each unit consists of a control case and one or several 60 kV modules up to the required voltage. For expansion above three modules, a HV expansion kit is required. This kit contains an anti-corona toroid rated for up to 300 kV, plus base extension legs and guy straps for support. The lightweight fiberglass control case includes all operating controls and meters, plus storage area for the base grounding probe, output resistor, and interconnecting cables.
