Transmission line frequency parameter tester working principle
working principle:
â—† Transmission line power frequency parameter tester can measure various parameters of positive sequence and zero sequence of various types of transmission lines, voltage RMS, current RMS, active power, reactive power and other parameters.
â—† Allow external voltage transformers and current transformers to perform extended range measurement.
â—† Transmission line frequency parameter tester voltage and current measurement circuit wide limit: the maximum voltage can be measured to 750V, without changing the gear to ensure accuracy. The instrument itself will not be damaged due to the wrong selection of the voltage range; the current can pass 100A current test.
â—† Large-screen, high-brightness liquid crystal display, full-Chinese menu and operating tips to achieve a friendly man-machine dialogue, touch buttons to make the operation easier, LCD with brightness adjustment, can adapt to the seasons of winter and summer.
â—† The user can print out the test data through the 232 interface external micro printer at any time (printer is optional).
â—† The transmission line power frequency parameter tester reserves the RS232 serial port for communication with the computer for users of high-voltage measurement vehicles, and can expand the verification data upload function to realize centralized data management.
