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 Dielectric Test System
 |
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 Precision Standard Capacitor
 |
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. |

RVM 5462 Recovery Voltage Meter
 |
Catalog ID: Recovery Voltage Meter RVM 5462 The instrument was previously marketed by Haefely under the brand name Tettex, but now only Diagnostics Kft. offers an improved, renewed version, the RVM-22. The Recovery Voltage Method is based on established knowledge: the phenomenon of the polarization of oil/paper impregnated insulation.Many “HIGH-VOLTAGE-WORKING PEOPLE“ have made this painful experience: of short-circuiting a high voltage capacitor (which was previously charged with a direct voltage), of measuring a voltage more or less 0 V and so believing that the capacitor is completely discharged, of touching the connectors of the capacitor and of feeling a |
FRA 5311
 |
Catalog ID: FRA 5311 The FRA 5311 Sweep Frequency Response Analyser detects transformer winding movements and mechanical failures due to mechanical shock, transportation or short circuits as defined in the IEC 60078-18. |
