For users with regular circuit breaker testing requirements that traditionally had to choose between low end instruments designed only for simple applications and versatile but costly high end instruments, Megger has introduced its new TM1700 range of circuit breaker analysers.

The technology used in the new instruments is based on Megger’s high end TM1800 series and features DualGround testing, which means that tests can be performed with both sides of the breaker grounded. This increases operator safety by eliminating the risk of high voltages being induced into the breaker under test.

The TM1700 instruments also incorporate active interference suppression, which means that they consistently deliver accurate and dependable results, including measurements of PIR values, even in electrically noisy environments such as electricity substations. A further important benefit is that all inputs and outputs are galvanically isolated, making it possible to perform all relevant measurements in one test without the need to change connections.

The instruments are available in four versions, allowing users to choose the specification that best matches their requirements as well as between stand alone and PC controlled units. Stand alone models incorporate a large colour touch screen and offer a user interface backed by software wizards that simplify the production of custom test templates. Computer controlled models are supplied with a PC compatible software package that provides comparable functionality. A range of accessories are also available with the analysers.
