Hard Disk Storage - Ametek TR-2100 Operation Manual

TR-2100 User Manual
• On-line Switchgear & Battery Monitor
Because the TR-2100 is attached to strategic protection equipment, it can be used for
condition monitoring. Circuit breaker operations are recorded and analysed by the Expert
System. The measurements from each operation are stored in a database and these are used
in a number of programmable contact wear formulae.
The accumulated number of operations, arcing current and arcing time all contribute to wear
of the main contacts. By selecting one of the three standard formulae, the service period for
each piece of switchgear can be determined.
The TR-2100 can also monitor the breaker coil currents and battery voltage. This provides
more information on the state of the switchgear and the state of the battery under load.
• Energy Meter
The real power values from the logger are used to compute energy demand over a variable
interval. Peak demand and load profiles can be tracked to minimize energy costs.
• Plant Commissioning Diagnostic Tool
The extensive sets of functions within Display Station Analysis (DSA) allow it to be used
for the installation and commissioning of a power plant. Test records can be taken either
manually or automatically and analyzed with DSA to check for correct operation of
switchgear, transformers, etc. These records can be archived and used for comparison during
future diagnostic checks.

Hard Disk Storage

The TR-2100 is fitted with a hard disk drive. This provides a large non-volatile data storage
capacity for transient and disturbance fault records. It also stores the disturbance and long-
term logger data. The disturbance logger stores RMS and phasor information for every
channel for up to 2 weeks. The long-term logger saves the maximum, minimum and average
voltages, currents and frequency every minute. It also records certain power usage and
power quality data. This log is 52 weeks long and requires approximately 8 Mbytes of
storage for every 8 input channels.
