Megger 100 KV 50 HZ TEST SYSTEM HPA 100/110/120 AC and 130 DC

The Megger HPA 100 series, including the HPA 100, HPA 110, HPA 120 AC, and the versatile HPA 130 DC, represents a line of robust high-voltage test systems designed for comprehensive testing and diagnostic tasks within electrical utilities. These systems are specifically tailored for integration into cable test vans, providing powerful and reliable solutions for on-the-go high-voltage testing and fault localization in various capacitive objects.

Core Features Across the HPA 100 Series:

Powerful Testing Capability: The series is capable of continuous testing with AC voltages up to 100 kV RMS at 5 kVA, making it suitable for a wide range of applications including transformers, switchgear, isolated busbars, and bushings.

Low Noise Level: With an own noise level below 1%, these systems are particularly well-suited for sensitive partial discharge (PD) measurements, a critical aspect in maintaining the integrity and longevity of electrical infrastructure.

Built-in Overcurrent Protection: Safety is paramount in high voltage testing, and the built-in overcurrent protection ensures safe operation under all conditions, protecting both the operator and the equipment from potential overcurrent incidents.

DC Testing Capability: The HPA 130 model expands the functionality with DC testing capabilities up to 130 kV, thanks to an optional rectifier attachment. This versatility allows for comprehensive testing regimes that encompass both AC and DC applications.

Model-Specific Details:

HPA 100: Dedicated to 100 kVRMS for AC testing, suitable for standard AC high voltage needs.
HPA 110: Steps up the capacity to 110 kVRMS for AC testing, offering an enhanced range for more demanding applications.
HPA 120: Further extends the reach to 120 kVRMS for AC testing, tailored for applications requiring higher voltage levels.
HPA 130: Unique in its dual capability, it supports both 100 kVRMS AC and 130 kVRMS DC testing, making it the most versatile unit in the series.

Design and Usability:

The two-piece design of the HPA 100 series ensures enhanced safety and flexibility. The separation of the control unit from the high-voltage unit allows operators to manage the system from a safe distance, minimizing risk during high-voltage operations. The control unit itself is robustly equipped with a variac for precise voltage control, current/voltage display instruments for monitoring system status, a timer for managing test duration, and a comprehensive safety circuit that enhances operational security.
