Product Details
High Voltage Different Frequency Transmission Line Parameter Test
System
Product introduction
ZXXL-Y Transmission Line Test System is a new generation power transmission line frequency parameter
testing system. It equips with frequency conversion testing power,
DFT Digital Filtering Technique, which eliminates strong
interference from power frequency electric field, and ensures the
safety of equipment, convenient, fast and accurate measurement.
Features
1. Quickly and accurately test the positive sequence capacitance,
the positive sequence impedance, zero sequence capacitance, zero
sequence impedance, also can measure the mutual inductance and
coupling capacitance between lines ;
2. High Anti-interference ability, accurate and reliable
measurement;
3. Easy operation, equipped with large LCD and American rotating
mouse and micro printer
4. Simple wiring, only connecting with tested down leads to finish
all line parameter measurement
5. High speed micro-controller as inner core, integrated structure
6. Fast testing process, one sequence parameter testing time is 1
min
7. Supplied with three groups different frequency power supply for
selection: 42.5Hz/57.5Hz, 45Hz/55Hz, 47.5Hz/52.5Hz, easily isolate
the power frequency and noise wave to ensure high precision
measurement of small signals.
