HSC-II Line Parameter Tester
Technical Parameters
1. Functional features
1. It can measure the positive sequence and zero sequence, phase-to-phase, line-to-ground and other related parameters of the transmission line, voltage effective value, current effective value, active power, reactive power and other parameters.
2. It allows external voltage transformers and current transformers to perform extended range measurements.
3. Wide voltage loop limit: The maximum voltage can be measured up to 750V, and the accuracy can be guaranteed without switching gears. The instrument itself will not be damaged due to the wrong voltage gear selection.
4. Large screen, high-brightness LCD display, full Chinese menu and operation prompts realize friendly human-computer dialogue, touch buttons make operation easier, LCD with brightness adjustment, can adapt to winter and summer seasons.
5. The instrument is equipped with a micro high-speed thermal printer, and users can print out the test data at any time through the micro printer.
6. For users with high-voltage measurement vehicles, the RS232 serial port for communication with the computer is reserved, which can expand the verification data upload function and realize centralized data management.
