345 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL
The EnerVista 3 Series Setup software may be used in on-line mode (relay connected) to
directly communicate with a relay. Communicating relays are organized and grouped by
communication interfaces and into sites. Sites may contain any number of relays selected
from the product series.
The System Setup page will be used as an example to illustrate the entering of setpoints.
Inthis example, we will be changing the power system setpoints.
1. Establish communications with the relay.
2. Select the Setpoint > System Setup > Transformer menu item.
3. Select the Transformer Rating setpoint by clicking anywhere in the parameter box.
This will display three arrows: two to increment/decrement the value, and another to
launch the numerical keypad.
4. Clicking the arrow at the end of the box displays a numerical keypad interface that
allows the user to enter a value within the setpoint range displayed near the top of the
keypad: Click = to exit from the keypad and keep the new value. Click on X to exit from
the keypad and retain the old value.
5. For setpoints requiring non-numerical pre-set values (e.g. Transformer type below),
clicking anywhere within the setpoint value box displays a dropdown selection menu
arrow. Select the desired value from this list.
6. For setpoints requiring an alphanumeric text string (e.g. "relay name"), the value may
be entered directly within the setpoint value box.
7. In the Setpoint > System Setup > Transformer dialog box, click on Save to save the
values into the 345 . Click YES to accept any changes and exit the window. Click
Restore to retain previous values. Click Default to restore Default values.
