 DVS3 HP
The DVS3-HP is the higher-power version of the T&R DVS3, offering
more than twice the output power of the original DVS3. The exceptionally
easy to understand user interface of the DVS3 is retained, allowing simple
testing of complex voltage and loss of mains protection systems.
Equally at home in a commissioning, maintenance, or laboratory
environment, the DVS3-HP is a truly flexible system. The DVS3-HP has been
designed using the latest digital technology to generate a highly stable and
accurate output with very low distortion. Each phase output is individually
adjustable for voltage and phase angle. In addition, full control of
frequency is available. Step changes of any quantity may be generated with
automatic timing of the response of the relay under test.
The unit is controlled by a simple user interface with context sensitive
menus. Values may be either typed in at the keypad or smoothly varied using
a digital potentiometer.
The DVS3-HP is ideally suited to testing G59 protection, including loss
of mains protection. Vector surge and df/dt (ROCOF) relays may be simply
tested and timed, as can other protection requiring one to three voltages,
including:
- Under and over frequency relays
- Under and over voltage relays
- Syncronising relays
- df/dt & ROCOF relays
- Vector surge relays
- Transducers
