Power Quality Recorder Simeas-R<br />
2.1 Overview<br />
The shortcut SIMEAS R means "SIemens MEASurement Recorder"<br />
The power quality recorder SIMEAS R is used for quality assurance in power stations,<br />
<strong>and</strong> extra-high, high-voltage <strong>and</strong> medium-voltage installations. SIMEAS R records<br />
power faults <strong>and</strong> power quality <strong>and</strong> moni<strong>to</strong>rs the secondary <strong>and</strong> primary technical<br />
facilities. It has an integrated digital fault recording system with an integrated fault<br />
recorder, power <strong>and</strong> frequency recorder, digital recorder <strong>and</strong> an event recorder system.<br />
The signals are sampling with a high sampling rate (256 times the base frequency with<br />
64-fold oversampling) with a high degree <strong>of</strong> accuracy (measuring fault < 0,2 %), <strong>and</strong> a<br />
high resolution (16 bit). With its new transducer concept it is capable <strong>to</strong> record signals<br />
with DC components. For transfer an configuration it can be equipped with direct<br />
communication interfaces <strong>to</strong> an analog or digital telephone network, LAN or WAN<br />
using TCP/IP pro<strong>to</strong>col or null modem. Through this communication possibilities it<br />
has the capability for remote diagnosis <strong>and</strong> full commissioning via modem or network.<br />
