The RIV meter is an instrument for the measurement of Radio Influence Voltage according to NEMA 107-1987 and other relevant standards (ANSI 63-2-1996, VDE 876, DIN EN 55016-1-1).
The instrument has a bandwidth of 9 kHz and a tunable center frequency of 10 kHz-10 MHz. The RIV meter is an ideal instrument to replace outdated RIV measurement instruments in transformer testing labs.
RIV-3 system consists of desktop acquisition and display unit (three channel), calibrator, 3 channel multiplexer, partial discharge free coupling capacitors and partial discharge free injection capacitors.
Desktop Acquisition and Display Unit (Three Channel):
Backlit LCD Display
Meter display 0-2500 μV (@ k=1)
Auto-range function
Automatic storage of current settings
RIV bandwidth 9kHz (ANSI C63.3-1996)
Reference channel for RIV calibration
Center Frequency 100 kHz – 2MHz (10 kHz steps)
Serial Interface (USB, 57.6 Bit/s fixed)
Calibrator Model CAL3A:
Selectable level 10 μV (20dBμV) to 10 mV (80 dBμV)
Available in steps of 1-2-5
Error rate of +/- 5%
Adjustable Frequency between 600kHz & 1350kHz (50kHz steps)
Comes with ISO17025 Calibration Certificate traceable to DKD
3 Channel Multiplexer Model MUX3:
Built in multiplexer with three inputs for RIV measurement and three inputs for voltage measurement
Firmware offers individual setups and calibration factors
Second line of push buttons for direct channel selection
Note: Multiple channel RIV systems require a coupling capacitor per channel. For a Coupling Capacitor to operate in the range of 50 to 500 Hz, it requires the next higher rated voltage capacitor.
