Surge Arrester Leakage Current Analyser Online, wireless measurement of 3rd harmonic resistive leakage current of HV/EHV surge arresters with system harmonics compensation... SA 30i+

The Product SA 30i+ Surge Arrester Leakage Current Analyser SA 30i+, the wireless Leakage Current Analyser from SCOPE is a state of the art, on-line test system for residual life assessment of Metal Oxide Surge Arresters. The instrument measures and directly displays the values of Total Leakage Current and Third Harmonic Resistive Leakage Current. It provides system harmonic compensation as per the IEC 60099-5-B2 method. It provides Corrected Resistive Leakage Current after applying correction factors for change in system voltage & temperature. The SA 30i+ can be pre-loaded with the LA...

Method 1: Third Harmonic Resistive Leakage Current Measurement with System Harmonic Compensation (IEC 60099-5-B2) When the voltage is applied to the arrester, due to non-linear voltage current characteristics of metal-oxide used in arresters, harmonics are generated in the leakage current. The third order harmonics, which is predominant depends on resistive current of arrester. The magnitude of third order harmonics in the leakage current can be used as indicator of resistive current. The resistive component depends on applied voltage and temperature. However system voltage itself may...

SA 30i+ Corrected Third Harmonic Current SA 30i+ has in-built temperature sensor which measures the ambient temperature & corrects the result to 20°C, as per the IEC 60099-5. It also corrects the results to the rated voltage of arrester to eliminate the effect of change in system voltage during measurement. These corrected results can be used for comparison of results over a period. By default, the correction factors for voltage as well as temperature are programmed as per the graphsgiven in IEC standard. The instrument also has a facility to program the voltage correction table. User can...

SCOPE SA Data: PC Downloading & Analysis Software SA Data is Windows™ based software. It enables users to create and store library of number of LA IDs along with relevant information pertaining to each LA like LA Identification, Type, Serial Number, Location, Rated Voltage etc. User can create this library off -field, upload it to the instrument via USB and use it on-field during testing, saving on-site testing time. Results stored under such LA IDs in the instrument can be transferred back to SA Data, where they are stored in a structured & comprehensible format. Trend Analysis for trending of...
