Product Description

Hm2008c Transmission Line Parameter Test set
Advantage
1. Quickly and accurately complete cable measurement of positive capacitance,zero sequence capacitance, positive/zero sequence impedance, it can also test mutual inductances and coupling capacitance between lines;
2. Strong anti-interference ability, it can accurately measure under ratio 1:10 of different frequency & power frequency;
3. External wiring is simple, only one time connection is okay;
4. The instruments built in high speed single chip as the core, to realize the integration of test power, instrumentation, computational model, a truck equipment was condensed into one unit instrument.
5. The instrument adopts 320 * 240 large LCD display, american rotary mouse operation, embedded printer to print the results, operation is very simple;
6. The instrument test process is quick, it can automatically complete test mode control, pressure control and data measurement and lifting calculation, print measuring results, 1 minute can finish an order parameter measurement, test time is short, workload is greatly reduced, 20 minutes can complete traditional test method;
7. Good measurement accuracy, the instrument itself provides three groups close to the power frequency different frequency: 42.5Hz/57.5Hz; 45Hz/55Hz; 47.5Hz/52.5Hz; easy separation power and clutter interference, effectively realize high precision measurement of small signal.
