4.3.2 Setup Nameplate
Nameplate values are primary and secondary voltages (or ratios) associated
with a given transformer. This information is available on the Nameplate
of the transformer. The measured results will be compared with selected
(edited) Nameplate values and Deviation will be displayed and stored in %
relative to these values.
The DTR
®
8510 allows the storage of 10 Nameplate voltages or ratios
which can be individually selected for a given test.
NOTE:
• The Nameplate list of up to 10 transformers can be written to and
saved only using DataView
®
software. The values in the list can
be edited for use but cannot be saved from the front panel.
• The keys on the front panel can select any one of the 10
transformer Nameplate values. Once the transformer values
are selected, they can be edited to a new value using the ▼,
▲ and
ENTER
keys. When the new values are selected (even
if they are not edited to new values), it becomes the Present
Nameplate and will be used for all subsequent VT/PT and CT
measurements. Deviation will be reported and stored using these
values.
• The Present Nameplate values will be retained in memory even
if the instrument is turned OFF and turned ON. However, it will
not be saved in the list from which it was originally selected.
• The user can select another Nameplate from the list in the
future and may or may not edit the values. As soon as the new
Nameplate values are selected (and/or edited), it becomes the
new Present Nameplate.
