Megger AC HV TEST SETS HPG35 HPG50 HPG58 and HPG78

Megger’s HPG series AC high voltage test sets are renowned for their reliability and flexibility in performing high voltage AC tests. The series includes four models: HPG35, HPG50, HPG58, and HPG78, each designed to meet specific needs in electrical testing.

Core Features Across the Series:

Powerful System: Each unit can operate continuously at 1.2 kVA, and for short durations (up to 60 minutes), they can perform at an increased capacity of 3 kVA. This robust performance ensures that they can handle demanding test conditions.

Compact and Maintenance-Free: The design of these test sets focuses on ease of use and minimal maintenance. Their compact form factor is particularly advantageous for setups where space is at a premium.

High Voltage Transformers: Built with cast-resin, the high voltage transformers in these units ensure durability and reliable performance under high stress and environmental conditions.

Modular Design: The separation of control and high voltage units enhances safety and usability. This two-piece design allows the operator to manage the system from a safe distance, minimizing the risk during high voltage operations.

Adjustable Voltage: Voltage can be adjusted continuously, providing precise control over test conditions, which is crucial for sensitive electrical components.

Model-Specific Features:

HPG 35: Capable of AC testing up to 35 kVRMS, this model is suited for routine testing of electrical infrastructure components such as switchgears and transformers.

HPG 58: With a capacity to test up to 58 kVRMS, the HPG 58 is ideal for medium voltage plants and systems, ensuring they meet safety standards and operational reliability.

HPG 78: The most powerful in this series, the HPG 78 can conduct AC tests up to 78 kVRMS, designed for high capacity and critical system components requiring rigorous testing protocols.

Versatility and Upgradability:

These test sets operate at both 50 and 60 Hz, making them versatile for different regional standards. They are primarily AC test sets but offer the flexibility to be upgraded to DC capabilities through an optional one-way rectifier. This adaptability makes them suitable for a broad range of testing scenarios, including but not limited to switchgears, current transformers, and other medium voltage components.

Operational Efficiency:

The control unit features a variac for voltage adjustment, integrated current and voltage display instruments for real-time monitoring, a timer to set test durations, and a comprehensive safety circuit to protect the user and the equipment.
