The High Voltage, Inc. (HVI) PTS Series 80 kV (specifically the PTS-80 model) is a highly reliable, portable DC test set designed for both field and shop environments. It functions as a two-in-one instrument: a high-voltage DC hipot (dielectric withstand tester) and a high-voltage megohmmeter (insulation resistance tester). This equipment is essential for testing the insulation integrity of high-voltage cables, switchgear, motors, transformers, and other electrical apparatus to ensure safe and reliable operation.

Here are the key features of the equipment:

• Dual Functionality: Serves as both a DC hipot (capable of outputting up to 80 kV DC) and a megohmmeter, allowing technicians to perform both withstand tests and insulation resistance measurements with a single unit.

• Continuous Output Control: Features a continuously adjustable output voltage from zero to the maximum 80 kV, enabling precise voltage application during step-voltage testing.

• Ample Current Capacity: Typically provides up to 10 mA of output current, which is crucial for quickly charging high-capacitance loads, such as long runs of high-voltage cable.

• Built-in Safety Mechanisms: Incorporates a zero-start voltage interlock (requiring the dial to be at zero before powering up), external interlock provisions, and an internal discharge solenoid to safely ground the equipment and the load when the test is complete.

• Rugged Metering: Equipped with robust, multi-range kilovolt (kV) and milliampere/microampere (mA/µA) meters for accurate monitoring of both the applied test voltage and the resulting leakage current.

• Field-Ready Design: Housed in a heavy-duty, single-piece enclosure built to withstand the physical demands and electrical interference typical of harsh substation and field environments.
