Description
Advanced Digital Solution for High Voltage Measurement
The Megger HVcompact Digital High Voltage Meter is a cutting-edge, precision-engineered instrument designed to deliver accurate and comprehensive high voltage measurements in demanding electrical testing environments. It combines an auto-ranging oscilloscope with a high-performance digital meter to display all relevant test parameters on a single screen in real time. Unlike traditional analogue devices, this solution provides additional analytical capabilities by showing both measured and derived values, including peak voltage (Û), RMS voltage (U RMS), peak-to-RMS ratio (Û/√2), crest factor, and measurement frequency. This ensures that engineers and technicians can comprehensively assess the voltage characteristics of the test object without switching between different measurement tools. Large-character display options further enhance readability, making it suitable for environments where rapid data interpretation is essential, such as high-voltage laboratories and manufacturing test facilities.
Precise Testing for Critical Power Components Worldwide
One of the standout advantages of the Megger HVcompact is its suitability for diverse and critical high-voltage equipment applications. This includes instrument transformers, current transformers, voltage transformers, high voltage cables, medium voltage cables, and switchgears used in power distribution networks. These components are integral to the reliability of electrical infrastructure, and their testing demands extremely accurate voltage monitoring and fault detection. The HVcompact is equipped with an adjustable divider ratio which allows it to be perfectly matched to varying test setups, regardless of whether they are in R&D laboratories, quality assurance departments, or on-site in power plants. With a maximum input of approximately 100 V RMS and reliable processing of voltage signals, it provides the precision and adaptability needed for consistent performance in global testing standards.
Intelligent Breakdown Detection and Voltage Safety Control
Ensuring device under test (DUT) safety is at the core of the HVcompact’s design. The system includes an adjustable voltage limit feature, allowing the user to define the maximum permissible voltage for a given test. If the voltage exceeds this set threshold, the device can trigger an external relay, effectively halting the test to prevent damage — for instance, by blocking a control panel’s ‘UP’ button or disconnecting the main breaker. A unique incipient breakdown prediction function further elevates safety: by detecting even minute voltage drops ahead of catastrophic failure, the device can intervene before a flashover occurs. Engineers can configure a maximum permissible voltage change rate (dU/dt), and when that limit is surpassed, the HVcompact stops the test instantly. This dual-layer safety mechanism makes it invaluable for critical asset preservation during HV testing.
Seamless Integration and Data-Driven Engineering Analysis
The HVcompact is not only a precise measurement instrument but also a powerful diagnostic tool thanks to its robust connectivity options. The front-facing USB serial interface enables direct connection to a PC, from which users can control testing operations and log measurement data. This is particularly useful when paired with analysis software for partial discharge monitoring, a vital aspect of high-voltage insulation assessment. The rear panel features a comprehensive range of connectors, including standard BNC inputs, ground terminals, relay connectors, recorder outputs (0–10 V), and TTL COM ports. Optional LAN and RS‑232 links expand integration possibilities, making the HVcompact suitable for automated test lines and networked laboratory systems. When paired with the optional HVpilot automation software, testing workflows can be streamlined significantly, reducing operator workload while improving reporting accuracy.
Ergonomic Design for Laboratory and Field Operations
The Megger HVcompact is available in two housing configurations: a 19-inch rack-mountable version and a half 19-inch desktop housing for tabletop use. The front panel features a backlit LCD with a resolution of 128 × 240 pixels, providing clear visibility of waveform traces and numeric values even in less-than-ideal lighting conditions. Five intuitive menu-driven keys — SCALE, RESULT, SCOPE, SETUP, and MAIN — allow for rapid navigation and adjustments, while the dual display modes (needle meter and oscilloscope) accommodate different operator preferences. Weighing approximately 3.5 kg with dimensions of 236 × 133 × 300 mm, the HVcompact strikes a balance between portability and robustness, making it ideal for both stationary laboratory setups and mobile testing environments. Its calibrated measurement chain is verified in a DAkkS-accredited laboratory in compliance with ISO 17025:2018, ensuring traceability and measurement confidence.
Setting the Benchmark in High Voltage Test Rooms
Adding the HVcompact to an existing high-voltage test setup modernizes capabilities without the need for full equipment replacement. It brings instant, on-screen visualization of all voltage parameters alongside an oscilloscope trace, which aids in fault analysis and validation of DUT performance. Its ability to store the voltage history preceding breakdown events in non-volatile memory allows engineers to review and understand failures in detail. The oscilloscope’s 197 samples per cycle provide fine temporal resolution, enabling the capture of subtle transient effects. The included recorder output facilitates analog signal transfer for external equipment documentation, while the relay interface ensures real-time integration into safety systems. This unprecedented combination of measurement accuracy, analytical power, and safety functionality makes it one of the most advanced high-voltage meters available today.
