Megger DC AND AC HV TEST SYSTEM HPG50-H, HPG70-H, HPG80-H and HPG110-H

The Megger HPG series, featuring models HPG50-H, HPG70-H, HPG80-H, and HPG110-H, represents a robust range of high voltage (HV) test systems designed for both AC and DC testing applications. These systems are engineered to cater to the demands of testing low capacity test objects across various industrial settings, enhancing safety and reliability in electrical component evaluation.

Key Features and Design:

• Separate Control and HV Units: Each system includes separated control and high voltage units, optimizing safety and flexibility during testing procedures. This separation allows technicians to operate the system remotely, minimizing risk during high voltage tests.
• Continuously Adjustable Voltage: The voltage on these systems can be adjusted continuously, allowing for precise control over testing conditions, which is crucial for sensitive and critical testing applications.
• Powerful Performance: The systems are capable of continuous operation at 1.2 kVA and can handle up to 3 kVA in short bursts of 60 minutes, accommodating a wide range of operational demands and test scenarios.
• Compact and Maintenance-Free: Incorporating cast-resin high voltage transformers, these test systems are designed for durability and require minimal maintenance, ideal for rigorous use in varied environmental conditions.
• DC Testing Capability: Each unit can be optionally upgraded for DC testing by attaching a rectifier to the high voltage transformer, further enhancing the versatility and utility of the system.

Model-Specific Capabilities:

HPG50-H: Offers AC testing up to 35 kVRMS and DC testing capabilities up to 50 kV, suitable for routine testing of electrical infrastructure components like switchgears and transformers.

HPG70-H: While specific details were not provided, this model likely fits between the HPG50-H and HPG80-H in terms of capability, offering a mid-range option.

HPG80-H: Can perform AC testing up to 58 kVRMS and DC testing up to 70/80 kV, making it suitable for more demanding testing environments such as medium voltage plants and systems.

HPG110-H: The most powerful in the range, capable of AC testing up to 78 kVRMS and DC testing up to 110 kV, designed for high capacity and critical systems requiring rigorous testing protocols.

Operational Flexibility and Safety Features:

The control unit of each system is equipped with a variac for voltage adjustment, integrated current and voltage display instruments for real-time monitoring, a timer to manage test durations, and a comprehensive safety circuit to protect both the operator and the equipment. 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, allowing for both short and extended testing periods based on specific requirements.

Ideal for field applications and laboratory settings alike, the Megger HPG series provides reliable, precise, and safe high voltage testing solutions, ensuring that electrical components and systems meet required specifications and regulatory standards. Whether for routine diagnostics or comprehensive system evaluations, these high voltage test systems are equipped to provide effective testing outcomes.
