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.
