Description

• DSQC664 Harmonic metering up to the 21st harmonic, total harmonic

distortion (THD), as well as harmonic derating factor.

• Phase-to-neutral voltage metering, volts-per-hertz, and system

frequency.

• Tap changer position.
• Current demand for each winding including DSQC664 peak values.
• Real, reactive, and apparent power for each winding, along with

the power factor.

• Energy metering (Wh and varh) for each winding
• Transformer loss-of-life and ambient temperature metering
• Analog inputs.
• 

3. Event recorder downloading tool.
4. Product information including model number, firmware version, additional

product information, and calibration dates.

5. Oscillography and data logger downloading tool.

 Select an actual values window to also open the actual values tree from

the corresponding device in the site list and highlight the current

location in the hierarchy.

For complete details on actual values, refer to Chapter 6.

To view a separate window for each group of actual values,

 Select the desired item from the tree.

 Double click with the left mouse button.

Each group will be opened on a separate tab. DSQC664 The windows can be re

arranged to maximize data viewing as shown in the following figure

(showing actual demand, harmonic contents, and current values tiled in

the same window):

Prior to commissioning the 745 relay, setpoints defining transformer characteristics,

inputs, output relays, and protection settings must be entered, via one of the following

methods:

• Front panel, using DSQC664 the keypad and display.
• Front panel RS232, rear terminal RS485/RS422, or Ethernet communication ports,

and a portable computer running the EnerVista 745 Setup software or a SCADA

system running user-written software.

Any of these methods can be used to enter the same information. A computer, however,

makes entry much easier. Files can be stored and downloaded for fast, error free entry

when a computer is used. Settings files can be prepared and stored on disk without the

need to connect to a relay.

All setpoint messages are illustrated and described in blocks throughout this chapter. The

745 relay leaves the factory with setpoints programmed to default values, and it is these

values that are shown in all the setpoint message illustrations. Some of these factory

default values can be left unchanged.

There are many 745 setpoints that must be entered for the relay to function correctly. In

order to safeguard against DSQC664 installation when these setpoints have not been entered, the

745 does not allow signaling of any output relay. In addition, the In Service LED is off and

the Self-Test Error LED on until the S1 745 SETUP  INSTALLATION  745 SETPOINTS value

is set to “Programmed”. This setpoint is defaulted to “Not Programmed” when the relay

leaves the factory. The SETPOINTS HAVE NOT BEEN PROGRAMMED diagnostic message

appears until the 745 is put in the programmed state:

Messages may vary somewhat from those illustrated because of installed options. Also,

some messages associated with disabled features (or optional features which have not

been ordered) are hidden. These messages are shown with a shaded message box.

• Keypad entry: See Using the Relay on page 1–3 for details on maneuvering

through the messages, viewing actual values, and changing setpoints.

• Computer entry: Setpoint values are grouped together on a screen in the

EnerVista 745 Setup software. DSQC664 The data is organized in a system of menus. See

EnerVista Software Interface on page 4–8 for details.

• SCADA entry: Details of the complete communication protocol for reading and

writing setpoints are given in chapters 8 and 9. A programmable SCADA system

connected to the RS485/RS422 terminals can make use of communication

commands for remote setpoint programming, monitoring, and control.
