The HCC consists essentially of a control unit, a capacitor charger and other auxiliary equipment for the operation of generators.
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.
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.
The Capacitor Calibration Kit CCK has been designed to measure the pulse output voltage of surge generators PG10-200, PG12-360 and PG20-100.
The safety test cabinets PA 50* are designed for high-voltage testing of components and PCB's etc.
- Max. test voltage 12 kV / 24 kV
- Safety interlock switch
- Warning lights
- acc. to VDE 0104
- (PA 5xx series)
For high-voltage testing of components, DUTs are available for various pulse generators. The use of these DUTs significantly reduces placement times and significantly increases throughput.
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.
The Capacitive Coupling Clamp, EFTC 2012, provides the ability to couple Burst / EFT pulses to data lines. It can also be used for coupling to main lines where no CDN is available, for example, high current lines >200 A.
The capacitive Coupling-/Decoupling Networks CDN 2402/2410 are used in combination with the Multi-CE5 and allows superimposition of surge and burst test pulses to up to four I/O signal lines. The test set-up is suitable for surge immunity testing of electronic systems and devices according to IEC 61000-4-4, IEC 61000-4-5 and IEEE 587.
The capacitive Coupling-/Decoupling Network CDN 2802 is used in combination with the Multi-CE5 & Multi-CE7 and allows superimposition of surge and burst test pulses to up to eight I/O signal lines.
