Megger TM1700 circuit breaker analysers

Description

Introduction to TM1700 Circuit Breaker Analysers

The Megger TM1700 series circuit breaker analysers represent a new standard in the evaluation and testing of circuit breakers, especially within high-voltage substations and industrial environments. These cutting-edge analysers are designed to provide users a seamless blend of reliability, accuracy, and safety, combining essential features previously available only in higher-end, more expensive systems. TM1700 is engineered to allow regular circuit breaker testing to be performed efficiently without forcing users to compromise between cost and valuable functionality. The design philosophy behind the TM1700 series is rooted in Megger’s decades of expertise and the highly successful TM1800 series, with the TM1700 bringing essential and most utilized capabilities to the mid-range test equipment market while upholding the highest standards in measurement and operational safety.

DualGround™ and Enhanced Operator Safety Features

Among the standout features of the TM1700 series is its innovative DualGround™ technology. This capability allows both sides of the circuit breaker under test to remain grounded throughout the testing process, drastically reducing the risk of high voltage induction and thereby making the test environment much safer for the operators. In substations where induced voltages are common, DualGround™ proves indispensable as it mitigates potential hazards. The entire construction and internal system of the TM1700 have been calibrated for use in noisy, high-voltage situations—delivering accurate timing measurements and PIR (Pre-Insertion Resistor) values even in harsh electromagnetic environments. Furthermore, all input and output connections are fully galvanically isolated, eliminating the need for repeated setups or frequent changing of test leads. This not only enhances safety but also streamlines the testing workflow considerably.

Applications and Dedicated Use Cases Explained

The TM1700 circuit breaker analysers are primarily utilized in high-voltage substations, industrial power distribution systems, and utility company maintenance sectors. Designed for both regular scheduled testing and troubleshooting, these analysers excel in environments where precise breaker timing, resistance, and motion analysis are critical. Their main applications include timing measurements of main and resistor contacts, analysis of PIR values, detection of contact bounce, and verifying the correct functioning of auxiliary switches. Thanks to DualGround™, the TM1700 series is ideal for sites demanding higher safety levels during live testing. The versatility provided by five different models (from fully standalone to computer-controlled devices) ensures adaptability for field engineers, laboratory testers, and system integrators. Their fast and accurate data acquisition is pivotal for preventive maintenance, reducing downtime, and supporting post-event analysis after grid faults or breaker operations.

User Experience: Touchscreen, Software, and Operation

A hallmark of the Megger TM1700 series user experience is its intuitive operation, facilitated by a large 8-inch color touchscreen and a highly visual software interface. The standalone models sport a comprehensive on-board operating system, allowing technicians to create, modify, and execute test templates with ease. For more advanced requirements, the PC-controlled variants integrate seamlessly with CABA Win software, offering sophisticated data management, report generation, and long-term trend analysis capabilities. The TM1700 positions itself as a “select, connect, inspect” solution: users simply select a suitable test template, connect leads as per on-screen instructions (including graphical diagrams), and perform the test by turning the measurement knob. This three-step workflow minimizes human error and makes routine or complex breaker tests both efficient and repeatable.

Robust Design for Industrial Substation Environments

Another key strength of the TM1700 analysers is their robust, substation-ready design. The instruments are built to function optimally within a vast temperature range, from -20°C up to +50°C during operation, and with storage capabilities extending to -40°C up to +70°C. They withstand high humidity levels (up to 95% non-condensing), further augmenting their suitability for field deployment in a variety of climate zones. The device is housed in a compact yet sturdy casing, with dimensions tailored for portability without sacrificing ruggedness. With a weight of 12 kg and a dedicated ergonomic handle, field engineers can easily transport the TM1700 across substations or between test benches. Its EMC and LVD compliance, along with universal mains power input, further ensure reliability and operational safety wherever deployed.

Flexible Models and Versatile Measurement Capability

The TM1700 series offers users the flexibility to choose among five models catering to distinct testing needs—ranging from pure data acquisition units (PC-controlled) to fully standalone analysers with an integrated human-machine interface. All models benefit from consistent internal architecture, including fast sample rates (up to 40 kHz), extended measurement times, galvanic isolation, and multiple test channels. Key measurement capabilities encompass timing analysis of main and resistor contacts, motion analysis with transducer support, current and voltage measurement, and support for digital incremental transducers and RS422 interface. Each main section boasts up to 6 timing channels and 3 analog input channels, backed by precise time base accuracy and high bit-depth signal processing for reliable detection and recording of test events even in the presence of substantial interference.
