The Megger HPG50-D, HPG70-D, and HPG80-D models represent a sophisticated line of compact AC and DC high voltage test systems, designed to cater to a variety of testing requirements for electrical components. These models seamlessly blend versatility with performance, offering options for both AC and DC testing.

Key Features of the HPG50-D, HPG70-D, and HPG80-D Systems:

Compact and Maintenance-Free: Each unit incorporates a cast-resin high voltage transformer that ensures durability and minimal maintenance, making them suitable for rigorous use in various environments.

Modular Design: The systems feature separate control and high voltage units, which allows for flexible setup options and enhances user safety by enabling operation from a safe distance.

Adjustable Voltage Control: The voltage on these units can be continuously adjusted, providing precise control over test conditions, which is crucial when testing sensitive components.

Powerful Operation: Designed to operate continuously at 1.2 kVA, these systems can also handle up to 3 kVA for short periods (60 minutes), accommodating a range of operational demands.

DC Testing Capability: The DC testing feature is facilitated through a voltage-doubler rectifying attachment, allowing the HPG50-D to reach up to 100 kV and the HPG80-D up to 160 kV. The HPG70-D, while not specified in the details provided, likely fits between these capacities, offering a middle ground with robust capabilities.

Applications and Functionalities:

Versatility: Suitable for both 50/60 Hz AC testing (35 to 58 kVRMS) and high-capacity DC testing, these units are highly versatile. This makes them ideal for a broad range of testing scenarios, including switchgears, voltage and current transformers, medium voltage plant components, and DC cables.

Control Unit Features: The control unit is equipped with a variac for fine voltage adjustments, current and voltage display instruments for monitoring, a timer to control test duration, and a safety circuit to protect both the operator and the equipment.

Operational Flexibility: The ability to excite the low voltage winding from zero to the maximum value ensures that a consistent output is available for a predetermined period, accommodating various testing protocols. This feature allows for both short and extended testing periods based on specific requirements.

Ideal for Field and Lab Use: The separation of the control and high voltage units not only enhances safety but also increases the practicality of these systems for use in both field and laboratory settings. This separation ensures that operators can conduct tests without the risk of exposure to high voltage, particularly in on-site environments.
