1 Overview
1.1 TESLA LITE System Description
The TESLA LITE power system recorder is a multi-time frame recording sys-
tem used to monitor electrical power systems. It can record up to 12 ac currents
and 6 voltage channels and 38 digital (status) channels and store up to 150 re-
cordings.
The TESLA LITE can record data simultaneously in three time domains: high
speed transient fault (seconds), low speed dynamic swing (minutes), and con-
tinuous trend (10 second to 1 hour intervals). A wide variety of triggers are
available to initiate recording.
The TESLA LITE system consists of the recorder and the TESLA Control Pan-
el user interface software. TESLA Control Panel user interface software pro-
vides tools to configure the recorder, retrieve and manage records and display
real time measured values. Control Panel also includes RecordGraph, a graph-
ical record display and analysis software tool.
An optional central station program - RecordBase Central Station - is available
to automatically collect and store records from multiple recorders. RecordBase
provides fast network-based access to collected records through distributed
RecordBase View desktop clients.
