Resistance tester SA 30i

leakage currenttemperaturesurge protection device

SA 30i, the 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 IEC 60099-5-B2. 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 identity details (LA Identification, Type, Serial Number, Location, Rated Voltage etc.) and tests conducted on the same ID of the arresters are saved under the same folder. Trend analysis software, SAData picks up this data and stores them in a similar fashion on a PC. This analysis software enables the user to take a decision to repair/replace the arresters considering safety limits. SA 30i is designed to work under the hostile electrostatic noise found in live EHV switch yards up to 765 kV FEATURES • An innovative design makes SA 30i simple, lightweight, portable, feature-rich. • Measures Total Leakage Current, 3rd Harmonic Resistive Leakage Current with System Harmonic compensation and Corrected Resistive Leakage Current. • In built temperature measurement facility enables calculation of temperature corrected leakage currents. • Correction of results to rated voltage of LA to eliminate effect of change in system voltage. • Date and time stamp on test results • Results are displayed on large font, Big, back-lit LCD, printed on in-built thermal printer and can be stored in memory of the instrument.
