DMI551 AC, DC és Lökőfeszültség mérő
 |
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 |
R 500 REF Referencia osztó
 |
Catalog ID: R 500 REF, RCZ 500 REF Reference dividers are used for comparative measurements for the calibration of measuring systems. Reference dividers type RCZ are designed for the calibration of voltage dividers for AC, DC, full and tail chopped impulse voltages. Of course they can be used for normal measurements also.Reference dividers type R are designed for the calibration of voltage dividers for full and front-chopped lightning impulse voltages. Also R dividers can be used for normal measurements.Reference dividers by Haefely meet all requirements of IEC 60060-2 in particular those with respect to measuring accuracy and step response. |
PSK AC Tesztrendszer
 |
Catalog ID: PSK Our PSK AC Dielectric Test Systems are specifically designed for test applications which require a stable output voltage, even if the load may change during testing. For example for heavy corona, wet tests or pollution tests to name a few. These systems are also especially useful for when the load is inductive, such as inductive voltage transformers.This system allows for a variable duty cycle and includes the option to add radiators or forced oil-cooling for extended duty cycles. The PSK systems are optimized for indoor or outdoor tests with long duration or continuous duty cycles.These products are |
3320 Precíziós normál kondenzátor
 |
Catalog ID: 3320 Air Isolated These standard fixed and variable capacitors are especially for precision measurements of high accuracy. Because of their high insulation resistance, small self-inductance and dissipation factor, these standards may be used within large frequency ranges up to very high frequencies. |
