Megger's TM1700 circuit breaker analyzer allows the user to achieve efficient and reliable circuit breaker testing in any environment. Additionally, galvanically isolated inputs and outputs make it possible to perform all relevant measurements in a single test, eliminating the need for new set-up and reconnections.

Applications include first trip measurement, coil currents, control voltage and contact timing tests. Additional tests may include auxiliary contact timing, vibration, motor currents, dynamic resistance measurement and motion.

Within the 1700 series, there are four models from PC-remote-controlled to fully stand-alone. All models can be managed from a computer using the data management and analyzing software CABAWin. The DualGround method makes the testing safe and time-saving by keeping the circuit breaker grounded on both sides throughout the test.

The timing measurement inputs are using an active interference suppression algorithm to ensure correct timing and accurate pre-insertion resistor values.

The TM1700 has all the functionality of the TM1600 and builds on its predecessor in many capacities. The operator of any TM1700 model may control the analyzer either locally or remotely. Additionally, the TM1700 comes with an optional current source for static and dynamic resistance measurement. Many analyzers use only one current source, requiring operators to string long, heavy leads and climb up and down ladders or use basket lifts to make changes for each interrupter.

The TM1700 series possesses high-resolution analog channels with 16-bit A/D converters and 40-kHz sampling rate on all channels. The multifunctional breaker control unit on the TM1700 allows for independent control of pulse generation per phase and automatic coil resistance measurement; offers dedicated automatic control voltage measurement and individual external coil current measurement per phase using an optional clamp-on CT. The advanced vibration analysis allows for a noninvasive and time-saving peek into the condition of your equipment.
