Test Every Asset. Anywhere. With Confidence.
SCOPE's portable test instruments are purpose-built for live HV, EHV, and UHV switchyards —
giving your engineers the tools to test circuit breakers, transformers,
cables, and power system components with accuracy and safety.
Since 1988, SCOPE has been India’s pioneer in designing portable, digital test and
measuring instruments for the power sector. Our instruments work reliably in the extreme
electromagnetic environments of live EHV and UHV switchyards — up to 1200kV — where
most equipment fails. With dedicated R&D, in-house manufacturing at Pune, and a product
range trusted in over 60 countries, SCOPE makes it possible to test any electrical asset in
the field, on schedule, and with complete confidence.
