The 50/100 kV AC Dielectric Test Sets are ac high-voltage sources for testing electrical insulation. The standard system includes a control/instrument cabinet, a high-voltage transformer assembly and all necessary cables including ground and input power.

The high-voltage transformer is installed in an oil-filled, heavy-duty, fiberglass tank permanently mounted on a cart with casters. Convenient points are provided on the tank top (0 to 100 kV) and side (0 to 50 kV) for connection to the high-voltage output. A voltage divider is permanently connected to the output terminals and installed inside the high-voltage tank for mechanical protection. A wing nut is provided on the cart for the ground connections. Storage space is provided on the cart for the control cabinet, instruction manual and cables.
