Validate Asset Condition. Prevent Surprises.
SCOPE T&M is SCOPE Group's Validate - vertical India's first organisation to design and manufacture test and measurement instruments for the high electromagnetic environments of EHV and UHV substations. With over 38+ years of field experience and instruments deployed across 60+ countries, SCOPE T&M helps operators test, commission, and monitor critical substation assets with confidence. From portable CB analysers to continuous online monitoring, every instrument is built for demanding site conditions and IEC standards compliance.
- India's first T&M instruments designed for EHV and UHV substation environments - since 1988
- Full voltage range coverage: 11 kV to 1200 kV, trusted by PGCIL, NTPC, and 60+ country utilities
- Portable testing and always-on online monitoring covering the full asset lifecycle
- IEC-compliant accuracy with fast field setup; backed by SCOPE's lifetime product stewardship
