SA 10i
SA 10i the Leakage Current Meter from SCOPE is a State of the Art, hand held, on-line test system for Residual Life Assessment of Surge Arresters. The instrument measures and directly displays the values of resistive and total leakage current.
The SA 10i can be pre-loaded with the LA identity (LA Identification, Type, Serial Number, Location, Rated Voltage etc.) and tests conducted on the same ID of the Arresters are saved under its own library created. Trend analysis software; SAData picks up this data and files 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 10i is designed to work under the hostile electrostatic noise found in live HV switchyards
Features
- This hand held design makes SA 10i simple, lightweight, portable, feature-rich, affordable.
- Measures 3rd harmonic resistive current, and the total leakage current
- In built temperature measurement facility enables calculation of temperature compensated leakage currents
- Correction of results to rated voltage of LA to eliminate eff ect of change in system voltage.
- Date and time stamp on test results
- Results are displayed on LCD and can be stored in the in-built memory of the instrument. 1000 test records can be stored
- The SA 10i is powered by easily available re-chargeable Lithium-ion batteries. It works for a day’s testing needs on a single charge
- The SA 10i is a switch-yard compatible instrument. This makes the instrument extremely convenient to use.
- USB communication port to transfer data to PC and Windows based PC Downloading & AnalysisSoftware.
- Data Management, Analysis and Trending through SAData software
