Intellectual Insulation Indicator 3 i Portable Device for

Intellectual Insulation Indicator « 3 i» Portable Device for On-line Insulation Monitoring

The Device Application The multipurpose « 3 i» device is for on-line insulation condition estimation in the following equipment: • 6 ÷ 35 k. V switchgears of various designs; • Terminations and joints of cables; • High-voltage gas-insulated equipment (Gas-Insulated switchgear, GIS) of any rated voltage; • The tanks of power transformers, breakers, etc.

The « 3 i» Delivery Set The standard delivery set: • • • Transport case, The « 3 i» device, Power supply, USB cable, Headphones, CD with software. Additionally can be equipped with external sensors «TEV» , «RFCT» and acoustic.

The main features of device • 2 -band PD - HF (0. 5 -100 MHz) and an acoustic - 40 k. Hz; • Save all of the measured data with the subsequent processing and viewing on a computer; • The possibility of using routing technology using RFID; • Possibility of calculating the life of equipment and the use of state of repair; • Capacity battery (more than 8 hours of measurement); • Reliable and secure housing case.

New features in version 2 device • New convenient and lightweight case • Reliable connectors • More powerful battery • External synchronization • Wi-Fi Interface • Remote control capability New firmware: • PRPD-distribution • Wi-Fi sensor mode • Additional settings • Improved power saving mode

External sensors The acoustic sensor The capacitive «TEV» sensor The inductive «RFCT» sensor

External sensors Sensors for reference synchronization signals PRF-1 and PFR-2 Test signals generator Acoustic channel: 40 k. Hz, 30 d. B, 100 pulses / sec TEV Channel: 30 d. B, 100 pulses per second

« 3 i» Operation Modes • AC int. – embedded acoustic sensor • TEV int. – embedded TEV sensor • AC int. + ext. – embedded and external acoustic sensor • TEV int. + ext. – embedded and external TEV sensor • RFID – measuring by RFID tag • Route – measuring by saved route • RFID setup – setting RFID tag by information of route

The «AC» modes • Simultaneous recording of one or two channels • Trend pulse amplitude • Color indication of excess thresholds • Gain indication • PD pulse detection

The «TEV» modes • Simultaneous recording of one or two channels • Trend pulse amplitude • Color indication of excess thresholds • PD pulse detection

The «RFID» mode • Reading data from RFID tag • Making measure according to parameters from RFID data

Examples of placing RFID tags Standart Mifare IEC 14443 -3

The «Route» mode • Selecting route • Making measure according to parameters from route

The Software INVA Portable – is powerful and easy-to-use program

Device settings low PD level, norm middle PD level, supervision high PD level, inspection alarm PD level, analysis The « 3 i» device can be configured using INVA Portable software.

Configuring the routes In the software the user creates the folder structure similar to the enterprise structure and downloads it into the device.

Configuring the routes For each point of the route or group of points can be specified the type of measurement and the thresholds.

Download and view measurements The software allows you to store measurements from the device to the computer, view and build trends.

Creating reports The program INVA Portable allows you to create three types of reports: • Report on the technical state of the equipment • Repair cycle report • Measurement cycle report • Report on the residual service life

Report on the technical state of the equipment This report shows the excess values of warning and alarm thresholds.

Repair cycle report This report shows the recommended time of equipment repair.

Measurement cycle report This report shows the time of the next measurement.

Report on the residual service life This report shows the estimated residual life of the equipment.

The End Also, the device and the software can offer a lot of other useful and convenient functions. Thank you for your attention.
