The PVS 100 consists of a base station (connected to a known reference
phase) and a mobile unit (both are identical), which is connected anywhere
in the network. The phasing is determined by comparing the phase angle at
the mobile unit to the one at the base station. Automatic comparison with a
direct indication of the phase identification is accomplished by synchronizing the two devices via a GSM connection and using GPS as a highly accurate
time base. The PVS 100 can be used anywhere thanks to its built-in rechargeable battery. The system can be directly connected to a test object of up to
400 V. For higher voltages, up to 120 kV, a high voltage sensor is used, which
communicates with the PVS 100 via wireless communication. The test status
and the phase indication are signaled using a visual display on the sensor.

DIGIPHONE
CI
The CI – Cable Identifier will safely identify a dead or de-energized primary
cable within a group of energized or de-energized cables as well as live secondary cables (incl.. neutrals) up to 240 VAC. The absolute safe identification
is based on polarity and signal magnitude of the DC pulse (up to 100 A) coming from the transmitter, which is picked up by the receiver and a clip-on
probe. The transmitter can operate of 120 VAC or internal battery (up to 50
hrs run time). The entire system functions without user adjustments and will
under no circumstances provide a ‘false‘ positive identification.
PVS 100
The Digiphone has become the most trusted pinpointer in the market. It
locates difficult or “quiet” faults on power cables based on the “lightning &
thunder” principle. The flashover at the fault generates both magnetic (lightning) and acoustic (thunder) signals. The time delay between the two signals
(speed of light vs. speed of sound) is displayed as a number. The smaller the
number, the closer to the fault! For this reason, the Digiphone will pinpoint
otherwise hard to find faults in conduit, under concrete and asphalt. The
bargraph (magnetic signal) lets the user stay on top of the cable route. The
Digiphone works with any manufacturer’s thumper.
