TR-2100 User Manual 5
1 Introduction
The TR-2100 substation monitor is designed using leading edge computer hardware and
software techniques. The high speed, high resolution recording, flexible triggering modes,
and long term recording modes make it ideal for capturing all forms of line transients,
protection operations, power quality surveys, real time display of station values, stability
monitoring, switchgear maintenance, sequence of events recording, metering, etc.
Input Connections
A maximum of 32 analogue inputs can be connected to standard protection voltage and
current transformers. Any input can be configured as a voltage or a current input when the
system is ordered. Changing the input range in the field requires a simple link selection. All
system inputs are DC coupled with a frequency response of about half the sampling rate.
In addition to the analogue inputs, there are also a maximum of 160 digital inputs for
reading the state of protection relays and switchgear. The digital inputs require a wetting
voltage from a source external to the TR-2100. Four status relays with pre-defined functions
are available. The power source can be AC or DC, and must be specified at the time of
order.
The TR-2100 can be specified to have 8, 16, 24 or 32 analogue inputs and up to 160 digital
inputs. The size of the cabinet depends on the combination of analogue and digital inputs
requested.
Recording Functions
The TR-2100 provides multiple concurrent power monitoring functions in one system. This
gives maximum functionality with minimum installation cost. Each of the recording modes
works independently of the others. The functions include:
• High Speed Transient Recorder
The high speed option allows all analogue inputs to be sampled synchronously up to 384
samples per cycle (19.20 KHz at 50 Hz, or 23.04 KHz at 60 Hz). The digital inputs can also
be sampled at this rate, although in most cases they would be recorded at an integer sub-
multiple.
The high speed recorder is used for special applications like lightning studies, monitoring
high speed switching in DC links, Static VAR compensators (SVCs) and Flexible AC
Transmission Systems (FACTS).
