DMI551 AC, DC és Lökőfeszültség mérő

HAEFELY_DMI551

Catalog ID: DMI 551

The Digital Measuring Instrument DMI 551 is an instrument for measurement of AC, DC and impulse peak voltages by means of 3 independent channels. The instrument can also be used for firing a generator or a chopping sphere gap and to trigger an oscilloscope or any other measuring device. The instrument has also implemented a flash detector to store and display the last voltage measurement and its polarity before a breakdown or flashover occurred.Typical main applications of the unit include measurements of a voltage divider output or for automated product testing where the DMI 551 is integrated into a complete control and measuring platform. A SCS  calibration certificate for AC and/or DC channels is optional available.

Jellemzők:
  • AC voltage measurement by capturing rams, peak and peak/√2 values
  • DC voltage measurement and evaluation of mean value and ripple factor
  • Impulse voltage measurement by capturing peak values of lightning or switching impulses
  • Impulse current measurement by acquiring the voltage across a current shunt
  • Triggering of generator and chopping gaps and any other measuring device
  • Flash detection of AC and DC flashovers. The generator can automatically be stopped from recharging
  • Remote control to operate the unit from a computer or a laptop
  • Plotter output for recording of AC and DC voltages on an external X-Y graph recorder
  • Easy to operate: Large LCD screen, case sensitive soft keys and special function keys reduce setup time and ensure intuitive and safe handling.
  • Simple to upgrade: Software codes are used for activating the individual measuring modes. Uninstallation, transportation, and reinstallation gets therefore superfluous.
  • Manual re-evaluation tool for all impulse parameters.
  • Accurate and reliable: Well established hardware and extensively tested software allows meaningful and credible measurements.
Alkalmazás:
  • High Voltage Measurements during
  • Transformer Testing
  • Switchgear Testing
  • Surge Arrester Testing
  • Research and Development
Rendszerbe integrálhatóság:
  • Remote control: RS232 or IEEE488
