| Model 2002 : The
Model 2002 Digital Fault Recorder is a state-of-the-art data collection and analysis
system. It's functions include digital fault recording, true sequence of event
recording, and disturbance recording. The Model 2002 is suitable for application in
an electrical utility substation or plant
environment. Model 3002: The Model 3002 Sequence Of Event
Recorder is a state-of-the-art data collection system. It is suitable for electrical
utility substation or plant environment applications to record contact state changes of
field devices such as electromechanical and microprocessor controlled relays.

| PMU2002: The new USI PMU2002 is an add-on software
package which allows existing USI Model 2002 Digital Fault Recorders to perform Phasor
Measurement Unit functions in addition to existing DFR functions. This add-on
package requires no additional hardware or modification to existing DFR installation. [Top] |

| Data Analysis Software
(DAS): Our Data Analysis Software is compatible with the Model 2002, 3002, and
HT-2000W recorders. Each recording system includes (1) single-user licenses in the
purchase price. Additional copies of the software and network licensing are
available for purchase. The DAS is capable of reading COMTRADE records in present
and past formats. This, plus its superior analysis tools and user friendly features
makes it ideal for viewing COMTRADE fault records from most any digital fault recorder. [Top] |

| Lightning Correlation
of Faults: Utility Systems now offers
lightning correlation in its Master Station software. Utilizing streaming GPS
lightning data and a database of transmission line structure coordinates, the Master
Station can automatically determine whether a fault was due to a lightning strike. [Top] |

| Trip
Indicating Relays: The TIR Relays are activated by sensing the presence of a current
in a trip coil. The special design is ideal for use with protective relays and
circuits associated with DFRs. [Top] |

| Model CTR-1001: Use our Current Transformer Assembly to measure your
secondary current circuits. With a 25 ohm terminating resistor, 1A=25mV. With
a 100 ohm terminating resistor 1A=100mV. These voltages can be connected to a DFR
sliding link terminal block and then to a DFR voltage input. Sliding links can be
opened for DFR calibration without risk of opening a current circuit. USI fault
records automatically convert the voltage input to a current measurement. [Top] |
