Megger HPG 35/58/78 AC – High-Voltage Test Systems

• Separate control and HV units keep operators at a safe distance.
• Maintenance-free cast-resin transformers ensure long-term reliability.
• Continuously adjustable AC voltage from 0 to 35/58/78 kV RMS.
• Powerful performance with 1.2–1.5 kVA continuous and up to 3.5 kVA for 60 minutes.
• Optional one-way rectifier upgrades the system for DC testing.

The Megger HPG 35/58/78 AC series delivers straightforward high-voltage testing in a compact, two-piece format. Engineers operate the control unit from a safe distance while the cast-resin transformer handles the high-voltage output. Continuous adjustment lets users set the exact test voltage needed, and the systems provide 1.2–1.5 kVA for extended runs or up to 3.5 kVA for short-duration tests. Consequently, they suit routine checks on switchgear, voltage transformers and MV plant components. The built-in safety circuit and over-current protection give operators confidence during commissioning and maintenance. With the optional rectifier, the same unit also supports DC testing when required. Robust, portable and easy to use, the HPG series meets everyday demands in substations and industrial environments.
