State of the art, on-line test system for Residual Life Assessment of Surge / Lightning Arrestors

Immediate assessment of condition of SA through direct display of the 3rd harmonic resistive leakage current and total leakage current in micro-ampere

Accurate and comparable test results made available

Inbuilt system harmonic compensation as per IEC 60099-5 B2

Temperature compensation through inbuilt silicon thermometer

Very fast measurement through specially designed, easily mountable, low-noise clamp-on CT and field probe

Inbuilt rechargeable battery tremendously enhances utility – AC supply connectivity is not required

Built-in self-calibration check facility along with option of revalidating the same with external calibrator

Library of available Surge Arrestors with identification information can be preprogrammed before test and loaded in the instrument for future use

Test results get stored automatically in folder of respective SA and downloaded to PC in similar structure

Authentic, time-stamped test results, data management through built-in real time clock, memory, PC connectivity & downloading software

Tamperproof test results through Inbuilt Thermal Printer

Trend analysis facility in Analysis Software enables present condition assessment and prediction of future performance – enabling a shift form schedule based maintenance to Condition based

Easy to use – self guided operation through interactive menu & keyboard

Designed to work reliably under live EHV switchyard conditions ensuring operator’s safety and repeatability of results

Lightweight, housed in rugged case enhancing transport worthiness
