Megger STVI Smart Touch View Interface handheld controller

Description

Revolutionizing Relay Testing with Smart Touch

The Megger STVI Smart Touch View Interface represents a quantum leap in convenience and capability for relay testing in the modern power industry. As Megger’s second-generation handheld controller, the STVI is designed specifically for seamless operation with both the latest SMRT and the proven MPRT relay test systems. At its heart, the STVI features a large, high-resolution color TFT LCD touchscreen, enabling highly intuitive navigation and rapid access to powerful testing functions. Engineers and technicians can now perform manual, steady-state, and dynamic relay testing tasks quickly and accurately, whether for simple overcurrent protection or advanced multi-stage differential schemes. The controller’s ergonomic design, centrally-located control knob, and rubber cushion grips support comfortable, left- or right-handed operation, while wide viewing angle technology on its 8.4-inch screen guarantees visibility even in direct sunlight.

Underpinning this interface is smart operation—users can quickly set parameters and launch preset test routines, saving considerable time during commissioning and maintenance. Even for demanding or high-volume test programs, the STVI is built for reliability and precision, representing the cutting edge of Megger’s relay test product engineering.

Streamlined Manual and Automated Test Execution

The STVI controller’s intelligent touchscreen transforms the entire test workflow with its manual and sequencer test screens. Technicians can use the manual test screen to set fault and pre-fault values, adjust output parameters in real time with the control dial, and track results visually through the color-coded display and vector graphs showing phase angles. Automated ramp, pulse ramp, binary search, and hybrid ramping modes are available for fast and precise relay pick-up and dropout tests—especially valuable for protection system verification and commissioning.

Beyond manual operation, the STVI’s built-in sequencer lets users construct complex test sequences, simulating dynamic power system events, reclosing, or load encroachment operations. Using the built-in stand, single-handed operation is a reality, particularly useful on busy substations or in harsh environments. The screen’s function buttons, together with a full suite of preset relay test routines, mean even complex differential, impedance, or transducer relays can be reliably tested without an external computer, massively simplifying fieldwork and reducing error risk.

Wide Application Range in Modern Power Grids

Among the STVI’s most valuable features is its broad applicability across modern and legacy relay systems. The controller is the ideal tool for commissioning, periodic maintenance, or troubleshooting of protective relays in transmission and distribution substations, power plants, and industrial facilities. Built-in test modules address overcurrent, over/undervoltage, impedance, differential (transformer, generator, and motor), transducer, and synchronizer relays. Enhanced software even supports advanced testing of frequency relays (including ROCOF and df/dt), power swing simulation for distance protection validation, and complex sequence simulation from SS1 files produced by systems like ASPEN or CAPE.

With Megger GOOSE Configurator (MGC), the STVI is uniquely qualified for IEC 61850 digital substations, mapping binary I/Os to GOOSE network messages for thorough horizontal communication verification. File playback of COMTRADE records enables true-to-life disturbance recreation, essential for both acceptance testing and post-fault investigations. Thanks to its dynamic testing and multi-stage trip/reclose capability, the STVI keeps pace with evolving smart grid protection requirements.

Effortless Data Management and Flexible Reporting

File management and data reporting have never been easier for relay test engineers. The STVI comes equipped with robust non-volatile internal memory for storing test configurations and results, with two USB ports provided for rapid report download or direct mouse/keyboard connection. The file management system lets users make, rename, or delete directories and files directly from the touchscreen interface. Field test data can thus be easily saved, transferred to a PC, or integrated into PowerDB for advanced analysis and documentation.

The report option allows custom information to be integrated into test headers, while STVI software automatically evaluates test results against theoretical curves and indicates pass/fail status visually—using red for out-of-tolerance and green for compliant results. This instant feedback improves both productivity and test result reliability, drastically reducing paperwork and manual entry errors. The multilingual interface with support for eleven international languages ensures that teams across the globe—regardless of local preferences—can benefit from streamlined, error-resistant testing and documentation.

Ergonomic Design Meets Rugged Field Requirements

Recognizing the challenging environments in which relay testing takes place, Megger has engineered the STVI to be both ergonomic and robust. Its plastic enclosure, reinforced with large rubber handles and a built-in stand, offers lightweight yet rugged protection consistent with MIL-PRF-28800F requirements for shock, vibration, and transit drop tests. An anti-glare, hard-coated screen ensures readability in the brightest sun and protection against scratches or impacts, while the IP30-rated enclosure means it is suitable for most indoor and sheltered outdoor environments.

Easy handling is supported by a centrally located control knob and well-placed function buttons, ensuring intuitive operation by both right- and left-handed users. The STVI’s compact dimensions (11 x 9.375 x 1.875 inches) and weight of just 3.6 lb (1.6 kg) allow for all-day use without fatigue, and the built-in stand allows hands-off testing, freeing up the operator for other tasks—a key advantage on busy substations or when tackling large numbers of relays.

Power, Connectivity, and User-Friendly Interface

The STVI’s hardware platform is as smart as its software. Powered via Power Over Ethernet (PoE) using a standard Ethernet RJ45 connection (compatible with IEEE Std 802.3 AF, 48V DC), the STVI draws power directly from supported SMRT relay test sets, or via an external PoE source for MPRT or SMRT1 units. Two onboard USB ports facilitate external device connection or file transfer, while Ethernet ensures fast, reliable communications for both data transfer and firmware updates.

A high-luminance, 262k color TFT LCD (640 x 480 pixels, 800 cd/m²) ensures detailed visual feedback, with a wide viewing angle—vital for teamwork in the field. The interface is highly responsive, touch-based, and supports multiple languages, providing essential feedback via visual (screen prompts, color codes) and audible alarms—instantly alerting operators to potential parameter or connection errors. This actual fusion of user-oriented interface and high-end hardware safeguards both efficiency and result accuracy.

Trusted Performance—Tested to Industry Standards

When it comes to safety, reliability, and durability, the Megger STVI complies with all major standards. Its design meets EN 61010-1, UL 61010-1, and CSA C22.2 #61010-1 safety standards, and it withstands harsh physical environments tested to MIL-PRF-28800F for mechanical durability and MIL-STD-810 for environmental hazards like extreme heat or cold. Electromagnetic compatibility is assured, with emissions and immunity certified to EN 61326-2-1, EN 61000-3-2/3, and relevant FCC standards.

This makes the STVI a trustworthy tool for utility engineers, industrial electrical staff, and service contractors who must maintain compliance under demanding global requirements. The built-in storage, intuitive navigation, and robust reporting features further ensure certified, auditable test results—supporting grid reliability, regulatory compliance, and continuous improvement in protection system performance.
