Details

The DVS3 mk2 is the new smaller, lighter, 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 mk2 is a truly flexible system. The DVS3 MK2 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 display on the DVS3 is back-lit and exceptionally clear. Menu options on the left are selected by dedicated buttons on the panel next to the display, allowing immediate access to adjust voltage, phase and frequency. Phase to phase and phase to neutral voltages are both shown on the display, along with frequency and phase information. A graphical vector diagram is shown, as is the state of the two contact inputs.



The DVS3 mk2 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
•Synchronising relays
•df/dt & ROCOF relays
•Vector surge relays
•Transducers

In conjuction with a current source (such as the 200ADM or 50A-3PH), the DVS3 mk2 can be used to test protection requiring current injection with a phase-shiftable voltage including:
•Directional relays
•Distance protection

•Phase angle relays



•Power relays



•Power transducers
