AC DC test equipment

High-Voltage DC Test Sets HTS 20-10 are designed for testing dc dielectric strength of components, insulations, air- and surface flash-over gaps. Also for testing SPDs according to IEC 61643-1. The test voltage can be adjusted from 0.2 kV up to 20 kV. The test voltage rises like a ramp from zero to the selected test voltage. The rate of rise can be adjusted from 100 V/sec up to 10000 V/sec. Then the test voltage remains at the selected value for the test time, which can be adjusted from 1 – 1000 sec. Figure: incl. option PA503

The alternating voltage testing set ACT ESTER 6 is suitable for the execution of the high- voltage test from isolations to VDE 0113, VDE 0700 part of 500, VDE of 0551 etc. IEC 60335, IEC 60204, IEC 60598, IEC 60745 The device essentially consists of a regulating transformer with a motor drive, a high voltage transformer, and a control unit. The output voltage can be adjusted by 0 - 10 kV.

Current-viewing-resistors Series ISM allows precise measurement of peak value and waveform of fast rise time current pulses. They excel by high bandwidth, low rise time and high accuracy of resistance value. Below their upper-frequency limit (-3 dB), the current-viewing-resistors ISM behave like pure dc resistors with frequency-independent resistance value. Because of their double coaxial design current-viewing-resistors, ISM are not susceptible to noise and electromagnetic interference.

The high-voltage measurement instruments HVM 2015 consist of a measuring amplifier for universal use with a digital touch display, a built-in high-voltage divider for direct measurement up to 10 kV / optional 20 kV and an external input for an external high-voltage divider, HVT***RCR, measurement, and display of voltages up to 300 kV. The HVM 2015 is designed for measuring ac- and dc- voltages and allows in addition measurement of the peak value of lightning and switching pulse voltages.

The Broadband high-voltage dividers series HVT...RCR are state-of-the-art measuring equipment with excellent high-frequency transmission characteristics. The high-voltage impedance consists of a precise metal film resistor and a high-voltage capacitor with a series damping resistor in parallel. The measuring cable with the termination network is an essential part of the divider. The termination network can be adjusted for an oscilloscope input impedance of 1 M? // 10 - 30 pF.

The Pulse Voltage Divider PVD 10-2 & PVD 10-3 have been designed to measure the pulse output of surge generators, e.g. a combination wave generators. It consists of the divider and a double-shielded coaxial cable. The measuring cable with the termination network is an essential part of the divider. The termination network can be adjusted for an oscilloscope input impedance of 1 M? // 10 - 30 pF.
