External partial discharges at high-voltage electrodes (corona) possess an acoustic spectrum, which extends to the ultrasonic region. Because of the strong directivity of high-frequency sound waves, ultrasonic detectors do not only allow detection, but also the localization of corona discharges, for instance, in switchyards, high-voltage test set-ups or transmission lines. The ultrasonic detector USD 38O1/38O2 operates at a frequency of approx. 33 kHz that is particularly suitable for external partial discharge detection. The combination of a highly directional ultrasonic microphone and a parabolic reflector system allows an exceptional directivity of the acoustic sensitivity. The microphone output signal is picked up by a selective amplifier and transformed into an audible signal. This allows a simple evaluation of the partial discharge intensity by headphones.

HCS 3-30 CAPACITOR DISCHARGE TEST SETUP 2 x 15kA

The surge current testing device HCS 3-30 is used for surge current testing of capacitor windings. The capacitor to be tested is on an adjustable voltage, 0,005 - 3000 V, charged and then discharged via a triggerable switch.

CURRENT-VIEWING RESISTORS WSM Type

WSM-type AC/DC current-Viewing resistors are designed for precise measurement of pulsed ac- and dc currents, for instance in industrial drives, pulsed welders and plasma physics apparatuses. Moreover, they are employed in short-circuit test facilities, measurement of start currents of fuel engines etc.

CURRENT-VIEWING RESISTORS ISM Type

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.

HVM 2015 High Voltage Meter 10kV, 20kV, ext. HVT 300kV

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.

HVT-RCR Broadband high voltage dividers

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.

PVD 10-2 / PVD 10-3 Pulse voltage dividers 10kV

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.

HCC xx-xx Capacitor charger with control unit

The HCC consists essentially of a control unit, a capacitor charger and other auxiliary equipment for the operation of generators.
