Description

Introduction to Megger OCR15D/OCR50D Test Sets

The Megger OCR15D and OCR50D Automatic Oil Circuit Recloser Test Sets represent the summit of modern recloser testing technology. Designed specifically to verify and validate the proper operation of automatic circuit reclosers under controlled and simulated overload as well as fault conditions, these units are invaluable in the electrical utility and equipment maintenance industries. With the rising demand for robust, reliable system protection and coordination, the OCR15D and OCR50D step forward, ensuring that the reclosers perform to the highest safety and efficiency standards. Their self-contained, mobile design allows for effortless transport and operation in diverse environments, adding to their desirability for field engineers and testing professionals who rely on accuracy, efficiency, and dependability.

Intuitive Operation and Technological Advancements

At the heart of the OCR15D and OCR50D lies a digital control and instrumentation system designed for simplicity and accuracy. Both models feature a bright, full-colour, high-resolution TFT LCD touch screen that streamlines the user experience, making operation surprisingly intuitive. The integration of Megger’s own OCR software within the PowerDB suite enhances both control and reporting capabilities, allowing users to run tests, save results, export data, and print comprehensive reports. Furthermore, digitized time-current characteristic (TCC) curves, which are included within the software, support users in interpreting test results and verifying compliance with manufacturer tolerances. This digital approach significantly shortens the training curve and eliminates many sources of human error, ensuring a consistently reliable testing process.

Comprehensive Testing for Modern Reclosers

The Megger OCR15D and OCR50D are engineered to test virtually all single-phase and three-phase direct-acting reclosers, regardless of whether they utilize oil or vacuum interrupters. Their applications stretch across leading manufacturers, including Cooper Power Systems, McGraw-Edison, Westinghouse, General Electric, Kearney, and Lexington Switch and Controls. Among the core tests achievable are minimum trip current evaluation (pickup point), determination of time-current characteristics, sequence of operation verification, operating time measurement, and total clearing time to lockout. These units are also enriched with primary injection testing capabilities, making them ideal for electronically controlled reclosers. In advanced utility testing environments, their ability to test even the cutting-edge vacuum interrupter-based reclosers underscores their indispensability.

Specialized Product Applications Across Industry

Beyond the basic operation checks, these Megger test sets support a wide array of specialized applications. They can conduct operational lockout tests on sectionalizers—critical devices in power distribution—for verifying programmed current pulse counts and operational thresholds. The OCR15D and OCR50D are also adept at high-current applications such as determining current transformer ratios, thermal relay testing, heat run performance, and direct-acting circuit breaker evaluation. Their powerful, programmable current sources, combined with precise measurement systems, enable comprehensive testing regimens that satisfy even the most stringent maintenance standards. With their ability to execute and record multiple test sequences, engineers can seamlessly transition between different test types, significantly increasing field testing productivity.

Impedance Compensation and Output Control Excellence

A distinguishing feature of the OCR15D and OCR50D is their sophisticated impedance compensation networks, designed to ensure stable output currents—even when faced with rapid changes in recloser impedance during tripping sequences. This guarantees that measurements remain consistent and precise, irrespective of coil impedance fluctuations. Both models offer variable high-current output ratings: the OCR15D provides up to 15 kVA, while the OCR50D delivers a robust 50 kVA, with corresponding short-time overload capacities of 45 kVA and 150 kVA, respectively. Their extensive, continuously adjustable output ranges are designed to accommodate a broad spectrum of test circuit impedances, making them suitable for both standard and extraordinary testing assignments in the field.

Safety, Robustness, and User Experience

Operator safety is paramount with the Megger OCR15D and OCR50D test sets. Each unit is housed in a rugged sheet-metal enclosure with a low center of gravity, equipped with large locking swivel casters for both stability and mobility. The inclusion of a comprehensive safety interlock system—paired with a foot switch—prevents accidental operator contact during high-current operations. Convenient front-panel busbar and terminal connections allow for swift changes between high-current and high-voltage tests with minimal setup time. Additionally, protective circuits safeguard each unit from overloads and short circuits, while an auto-ranging, electronic timing system with a digital display ensures every phase of recloser operation is precisely measured.
