The control and power supply of the Preamplifier unit (RPA1) is done by the acquisition unit through a standard coaxial cable which also transmits the partial discharge signal. The preamps do not use batteries or connections which may require maintenance or extra attention.

The RPA1 amplifiers also serve as impedance converters and line drivers. The power separation filter or coupling impedance is not loaded by the cable capacitance and signal cables as long as 200m* can be used without signal deterioration or loss of sensitivity. This technique provides extra safety margins in case of breakdowns and flashovers. The RPAl's are proven units which are performing reliably in more than 50 laboratory and field applications throughout the world.

Outstanding Features:

• Integrated LCD Screen: Displays an analog meter as well as an oscilloscope trace showing the test voltage, synchronous sine wave, and partial discharge pulses.

• Pushbutton Menus: All PD1R settings and calibration are done by pushbutton menus displayed on the LCD screen. The settings remain stored after the instrument is switched off.
• Automatic Scale Factors: Automatically calibrates and changes gain ranges. The PD1R also contains an autoscaled algorithm that adjusts the scale automatically.
• Unique Preamplifiers: Remote controlled and remote supplied preamplifiers and cable drivers are standard with the PD1R. The RPA1 is a standard; however, several other types are available depending on testing requirements.
