TR-2100 User Manual 1

Overview

The TR-2100 is a multi-function recorder that includes the features of many separate

instruments for monitoring a power system. These include protection operations, system

stability, and power quality. The voltages and currents on three phase lines are recorded via

standard instrumentation transformers to 16-bit accuracy. The state of protection relays and

switchgear can also be monitored via auxiliary switch contacts. Additionally, other

transducers can be connected to the TR-2100 for monitoring a wide range of parameters.

By providing a complete range of functions from a single connection to the power network,

the TR-2100 is a very cost effective instrument. Information from the recorder can be used

by a range of departments within a utility. A flexible reporting scheme enables the right

information to be sent to the right person at the right time. Because the TR-2100 can be

locked to a universal time standard, differential phase triggering can be implemented and

network wide state determinations can be made.

The TR-2100 can include the functions of any of the systems listed below.

• High speed multi-channel analogue and digital data recorder

• Transient fault recorder

• Protection monitor

• Generator monitor

• Sequence of events recorder

• Disturbance recorder

• Phasor measurement unit

• Stability monitor

• High speed logger

• Long term logger

• Dual channel recording frequency meter

• Multichannel recording power meter

• Vector meter

• Power quality monitor

• Harmonic analyser

• Flicker meter

• Oscilloscope

• Switchgear wear & performance monitor

• Station battery monitor

• Diagnostic & maintenance tool

Triggered Records

When an abnormal event is detected, the analogue inputs and the digital switch data are

stored in the TR-2100's memory. The stored data includes a period of time starting before

the event occurs, until after conditions have returned to normal. This data frame constitutes a

data record that may be printed in a graphical form with some initial measurements of the

transient event.

Loggers

The input voltages and currents to the TR-2100 are recorded as a maximum, minimum and

average RMS value every minute. The maximum, minimum and average frequency of two

selected channels is also recorded. The TR-2100 is fitted with a large hard drive and this log

will save data for 52 weeks before the data is overwritten. Selected blocks of data can be

downloaded from the TR-2100 for graphical display.

As an option, all the inputs values can be saved every other cycle (1/2 the system line

frequency) in a disturbance logger. This provides a continuous record for the previous 2

weeks. Harmonic, imbalance and energy data are also recorded in separate logs. These can

be recovered separately or together.

Power Quality Monitor

The TR-2100 can also record the harmonic profile of voltage or current inputs over a set

interval. This is used to measure trends with time or compare harmonic distortion at

different locations. There are a number of features as part of Display Station that allow

harmonic and other power quality data to be viewed.

Voltage dips can be classified by depth and duration to provide a profile of substation

performance. This can be used to compare performance at different sites, and show trends

with time.

The TR-2100 has a sensitive THD trigger mode that allows very subtle voltage distortions to

be recorded, which would otherwise be missed using normal triggering methods. This can

indicate progressive faults before they cause a serious problem.

Transducers

The TR-2100 computes a wide range of values from the recorded voltages and currents.

External transducers may be connected to the TR-2100 to extend the range of functions.

These could include pressure, temperature & position etc.

TR-2100 User Manual 3

Display Station

Display Station is a software application that runs on a standard Windows 95/98/NT based

PC. This provides a communication link to all TR-2100, TR-100, and DL8000 monitors via

an RS232 port, LAN, dial up modem, or WAN.

All the recorder parameters can be updated remotely, and the analogue signals and digital

status can be viewed on line. Data records can be downloaded to the user’s location, and

partial information such as a profile or cameo can be viewed to reduce communications

time.

Transient, logger and harmonic data can be displayed, analysed and printed using a range of

functions. An Expert System is used to classify faults into a number of categories for ease of

interpretation. Voltage Dip and Breaker Performance Analysis databases are updated for

quality and maintenance scheduling.
