UltraTEV Alarm - Brochure

UltraTEV Alarm™the Partial Discharge (PD) activity early warning systemContinuous monitoring of substation switchgear. Identifies faults and safety issues BEFORE they lead to failuresPRODUCT CODES: UTA1, UTAH, UTAH-GPRSmanan.jayswalText BoxUltraTEV Alarmbenefits Early warning of faults prevents failures Enables timely interventions when maintenance is required Warns personnel if switchgear is in a dangerous condition Excellent cost/benefit justificationfeatures Effective continuous monitoring with both ultrasonic and Transient Earth Voltage (TEV) sensors Multi-node sensor units can monitor 30+ assets simultaneously Receive alerts anywhere, via email or text message Simultaneously measures local humidity and temperature conditions Central hub unit LED indicators provide immediate indication of PD problemsoperation Sensor Nodes continuously monitor PD activity on the surface of assets in the form of TEV effects Microphones listen for PD activity inside assets in the form of ultrasonic emissions Nodes are linked to the alarm hub which indicates when PD activity in one or more assets is at critical level LEDs on the individual sensor nodes indicate which assets are affected Audible/visible alarms can be mounted outside the substation for added safety Can be used as a portable system or installed permanentlyALARM NODESignal InputBuilt in TEV sensor plus input for external ultrasonic sensorTEV Pass band 3 – 80 MHzUltrasonic Centre Frequency40 kHzINDICATORSPower/Running LED Bi-colour Red/Green LEDCurrent TEV Alarm Bi-colour Red/Green LEDHistoric TEV Alarm Bi-colour Red/Green LEDCurrent Ultrasonic Alarm Bi-colour Red/Green LEDHistoric Ultrasonic Alarm Bi-colour Red/Green LEDCONNECTORSPower and Alarm Signals 2 off four-way terminal blockUltrasonic Sensor Lemo socketCONTROLSReset Input Recessed Push-buttonTest Signal Recessed Push-buttonOUTPUTSAlarm Signals Pulse Code ModulationDIMENSIONSSize 105 x 105 x 50 mmWeight 0.26 KgPOWER SUPPLYLow Voltage DC 24V 36 mAENVIRONMENTALOperating Temperature 0 - 55°CHumidity0 - 90% RH non-condensingIP Rating 53EMCSafety Class SELVEMC Immunity Industrial LevelsEMC Emissions Domestic LevelsspecificationUltraTEV AlarmTMHub with GPRS OptionReceive condition alerts instantly via SMS text messages or email with this GPRS-enabled version of the hubHub without GPRS Option Volt-free contacts for optional SCADA connectionAdditional Sensor Nodes Built in TEV sensor complete with ultrasonic sensorUltrasonic Node Works directly with the Alarm Hub monitoring ultrasonic PD emissions onlyShort Microphone with Magnetic BaseLong Microphone with Magnetic BaseClose-Coupled Ultrasonic SensorAlarm Node Calibration CheckerTM Instantly checks that your Alarm Nodes are operating within specificationPortable 10-Node System Case Waterproof, robust, pull--along case with foam insertsaccessories and optionstel +44 (0) 151 339 4181fax +44 (0) 151 347 2404email sales@eatechnology.comweb www.eatechnology.comEA Technology LimitedCapenhurst Technology ParkCapenhurst, Chester UKCH1 6ESblahdblahdesign 10444/1/2To find out more, why not see the Podcasts at: www.eapodcasts.com
