Circuit breaker time and travel analysers with DualGround™ testing The TM1700 series of circuit breaker analysers provide reliable and accurate test results in noisy high voltage substations. With the TM1700 series of circuit breaker analysers, users with regular circuit breaker testing requirements no longer have to choose between low-end instruments designed only for simple applications, and high-end instruments that are versatile but costly. Drawing on our wide experience in circuit breaker testing, Megger developed TM1700 instruments to offer the most useful and widely used features of high-end analysers at a very attractive price. The technology used in the TM1700 is based on Megger’s popular and proven high-end TM1800 series, which remains the most attractive option for those who need the ultimate in circuit breaker testing flexibility. Among the many key features inherited by the TM1700 range is its DualGround™ capability. Dual ground testing enables you to perform tests with both sides of the breaker grounded. This configuration greatly 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 they consistently deliver accurate and dependable results, including measurements of PIR times and values, even in electrically noisy environments. Another noteworthy benefit is that all inputs and outputs are galvanically isolated, making it possible to perform all relevant measurements in one test without changing connections.
