Megger OCR8015/ 9150 Automatic oil circuit recloser tester

Description

Advanced Testing for Circuit Recloser Reliability Assurance

The Megger OCR8015/9150 Automatic Oil Circuit Recloser Tester represents a pinnacle of recloser testing technology, specifically engineered for the verification of automatic oil circuit reclosers’ operational integrity. These self-contained, mobile test sets were meticulously designed to faithfully duplicate real-world overload and fault conditions in a controlled environment, providing engineers and technicians with rigorous simulation and analysis capabilities. By employing microprocessor-based controls and measurement circuits, the OCR8015 and OCR9150 enable straightforward operation coupled with exceptionally accurate, reproducible results—an indispensable toolset for substations, maintenance fleets, and OEMs handling critical system protection devices. The testers’ ability to reproduce high-voltage test results accurately bridges the gap between laboratory and field performance expectations, ensuring power grid reliability and operational consistency.

High-Capacity Outputs Meet Modern Demands Easily

The OCR8015 outputs a continuous test capacity of 15 kVA, while the robust OCR9150 provides a formidable output of 50 kVA, with substantial short-term overload capabilities for both. Their variable high-current outputs, stabilized through advanced impedance compensation networks, mean they can rigorously test virtually all single-phase and three-phase direct-acting oil circuit reclosers from major manufacturers such as Cooper Power Systems, Westinghouse, General Electric, and more. The testers can be quickly adjusted to meet diverse test circuit impedances, with busbar connections facilitating high-current tests and insulated terminals supporting high-voltage applications. Designed for safe, efficient handling of output currents significantly above nominal ratings—when required for short durations—the units’ durability, control logic, and protection systems have made them industry favorites for both field and laboratory settings.

Simplified Testing Operations With Direct Microprocessor Control

By leveraging state-of-the-art microprocessor technology, the OCR8015/9150 minimizes operator error while maximizing data fidelity and test speed. The operator simply selects the intended test sequence, and the instrument handles current adjustment, mode selection, and timing automation—greatly reducing setup complexity. The built-in timing system digitally records all relevant intervals: operating time (trip time), reclosing intervals, as well as the total clearing time to lockout. If an operator omits to select the appropriate ammeter range, the tester’s error detection logic instantly warns and guides corrective action. All data—trip current values, number and sequence of device operations, and elapsed times—are stored internally and can be accessed with simple pushbutton recalls, streamlining both training and reporting.

Exclusive Applications in Modern Power System Environments

The Megger OCR8015/9150 is expressly designed not only to test oil and vacuum reclosers, but also sectionalizers and electronically controlled reclosers via primary injection. Typical applications include:

• Minimum trip current determination, identifying the lowest current at which the recloser will operate.
• Time-current characteristic testing, reliably simulating overloads at multiple current multiples (typically four to ten times the coil rating).
• Operating sequence verification, determining the correct number and order of device operations to lockout.
• Reclosing and lockout timing, confirming compliance with manufacturer and industry specifications.

For electronically controlled reclosers, primary injection ensures testing of not only the control electronics but also CTs, cables, and relay logic as an integrated whole. The testers can perform lockout and excess shot tests on sectionalizers, providing assurance they will operate after the exact expected number of circuit interruptions.

Industry-Leading Output Ratings and Overload Capabilities

Both OCR8015 and OCR9150 provide continuous and intermittent output current options, supporting an extensive array of test configurations. The output current can be finely adjusted, with impedance compensation engineered to minimize the current reduction that typically occurs with rising load coil impedance during testing. These instruments’ overload schedules are meticulously designed: at 100% rating, output can be maintained for 30 minutes; at 200%, 75 seconds; and at 300%, 25 seconds, followed by appropriate cool-down intervals. The OCR9150 in particular can output currents up to 2,000 A at 7.5 V, scaling to lower currents at higher voltages, making it suitable for almost any field scenario or load requirement. Such flexibility supports everything from CT ratio testing to direct-acting circuit breaker assessments, vastly increasing the testers’ operational utility.

Focused on Operator Safety, Mobility, and Reliability

Operator experience is paramount in OCR8015/9150 design. Each unit is housed in a rugged, single-sheet steel enclosure with a low center of gravity, integrated tow rings, lifting eyes, and four large locking swivel casters—ensuring both stability and easy mobility. The safety interlock system, in conjunction with a foot switch, enforces operator presence, guarding against accidental high-current contact risk. Illuminated panel indicators instantly convey operational statuses, while a ground-fault-protected accessory outlet permits convenient connection of ancillary equipment. The intuitive arrangement of controls and displays facilitates easy concurrent observation of both test set performance and device under test—critical during on-site troubleshooting or batch testing campaigns.
