Product Description


Series Variable Frequency Resonant AC Hipot Tester for cable on site test

Advantage

1) Placed way: the placement of variable frequency power for longitudinal and transverse, especially suitable for field operation and observe.
2) Shockproof protection: internal and external have special damping rubber support foot and protect aluminum boxes, which can effectively slow motion and lifting the bumpy transport the shock. Ensure the inverter power long-term stability and reliability.
3) Parameter display: touch or external mouse LCD interface display system.
Can show resonance voltage (namely test before setting goals voltage), test frequency, measure frequency, low-pressure voltage, low voltage electric current, voltage time, over-voltage protection, over-current protection, flash winding protection, phase booster and stage timing, operation mode switch, capacitor, inductance, frequency swap calculation, parameters, still can show inquiry on frequency curve, voltage curve can intuitivey judgment when trials resonance frequency accurately and stability.
4) Parameter Settings: big screen touch LCD backlit and external mouse directly in completing various parameters Settings. But on the initial frequency, termination frequency, starting voltage, phase booster and timing, measuring bleeder variable ratio, incentive change ratio, over-voltage protection, over-current protection, flash winding protection, test mode, capacitance inductance frequency swap calculation, parameter setting tips, and help parameters Settings or choice.
5) Test mode: touch screen and external mouse operation, there is automatic and semi-automatic, manual three operating status. With pressor, tuning (including manual, automatic), subsection pressurized and timing, running status, pattern switching, troubleshooting tips, capacitance inductance frequency swap computing functions, etc.
6) Protection function and information clew: having high-pressure over-voltage protection, low-pressure over-current, over-current protection, as well as detuning protection, zero, shem winding protection, emergency stop, undervoltage protection multiple protection function.
7) Automatic voltage function: system according to the test voltage or manually set of automatic tracking and boost results, stable test voltage, voltage stability can amount to 1.0%.
8) FM range and frequency resolution all can set: FM range set:30~300Hz,45~100Hz,200-300Hz, on-demand setting, can accelerate tuning process; The frequency resolution, according to the needs, presetting 0.1 Hz, efficiency and tuned in tuned balance between accuracy obtained optimization.
9) Frequency adjustment is divided into thick harmonic fine tuning, and automatic resonant point, guarantee for trials in the whole experiment resonant frequency process does not happen drift.
10) Storage measuring datas and print.
