Leakage Current Analyser for Surge Arrestor SA 30i

Product Description

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 changes 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.

• An innovative design makes SA 30i simple, lightweight, portable, and 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 the calculation of temperature-corrected leakage currents.
• Correction of results to rated voltage of LA to eliminate the effect of change in system voltage.
• Date and time stamp on test results
• Results are displayed in large font, Big, back-lit LCD, printed on an in-built thermal printer and can be stored in the memory of the instrument.
• SA 30i is powered by easily available rechargeable Lithium-ion batteries. It works for a day™s testing needs on a single charge
• The SA 30i is a switchyard-compatible instrument. This makes the instrument extremely convenient to use.
• Built-in standard calibration source and self-calibration check facility
• USB communication port to transfer data to PC and Windows-based PC Downloading & Analysis Software.
• The facility of extending CT & Field Probe signal to external oscilloscope.
• Facility for testing of GIS LAs available optionally
