Megger PS-9116 Microprocessor-based circuit breaker test

Description

Advanced Microprocessor-based Circuit Breaker Testing Solution

The Megger PS-9116 Microprocessor-based Circuit Breaker Test Set stands at the forefront of modern primary injection test sets, merging high-current transformer technology with SCR-controlled output and microprocessor-driven control systems. Designed specifically to maximize testing flexibility, the PS-9116 provides a robust platform for reliably assessing low-voltage circuit breakers. Its three-piece modular structure houses the essential components: a sophisticated controller and instrumentation package, a finely-tuned driver module, and a high-output module equipped with premium current sensors and transformers. This design ensures that users benefit from both portability and superior operational capability, accommodating the rigorous demands of industrial, utility, and service environments.

Modular Three-Piece Design: Lightweight And Rugged Portability

One of the defining attributes of the PS-9116 is its highly portable, lightweight, three-piece chassis. Each independent module—controller, driver, and output—comes encased in rugged, compact housing, facilitating effortless transportation between sites. The entire test set can be connected using sturdy interconnect cables or stab assemblies, allowing it to be as mobile as the work requires. With its thoughtful modularity, on-site setup becomes remarkably swift, minimizing the lost productivity often associated with heavy, cumbersome testing gear. Technicians find the PS-9116 easy to carry, straightforward to assemble, and highly durable for repeated use across various industrial or utility locations.

Automated Testing With The Model PLC-2000 Controller

At the heart of the PS-9116 lies the Model PLC-2000 controller and instrumentation package, engineered for complete microprocessor-based automation of low-voltage breaker testing. This state-of-the-art controller enables fully automated testing routines, data storage, and rapid printout capabilities. Incorporating a bright, easy-to-read vacuum fluorescent display, the controller offers clear alphanumeric output in both direct sunlight and dark environments. Sporting a high-accuracy digital timer, intuitive bar-graph LED displays, clock/calendar with battery backup, and real-time memory ammeter functions, the PLC-2000 ensures both technical precision and convenient user experience. Operators appreciate the programmable test parameters and built-in safeguards, guaranteeing safe testing procedures.

Maximum Testing Versatility And Application Range

The applications for the Megger PS-9116 are broad and critical to maintaining electrical safety and reliability. Designed to test low-voltage power circuit breakers up to 1600 amperes frame size, it is ideally suited for use in industrial plants, electrical utilities, and third-party testing service companies. The device is equally adept at verifying current transformer ratios and evaluating both thermal and magnetic motor overload relays. In series configuration, its impressive voltage output further enables precise primary injection testing of high-voltage breakers and protective relays in substations. The test set’s ability to deliver instantaneous output currents up to 19,200 amperes and maintain continuous currents of 1,600 amperes renders it indispensable for comprehensive circuit breaker maintenance and system commissioning applications.

User-Focused Features For Efficient Field Operations

Engineered for field and office efficiency, the PS-9116 features a motorized vernier for precise current adjustments, programmable test durations, and instantaneous test result printouts via RS-232 interface. The unit’s modular interconnecting cables are polarized for error-free assembly, reducing manual setup and teardown times. Clearly marked indicator lights supply quick, unambiguous feedback on operational status—from thermal condition and output-on, to continuity and interlock signals—ensuring operators are always informed. The device’s memory ammeter and bar-graph display aid in both overcurrent and instantaneous trip testing, making every operation faster and more traceable, with results easily stored and recalled for compliance or maintenance logs.
