Industries & Applications
CIE instruments are in daily use across India's critical infrastructure — from generating stations to rolling stock workshops.
Power Utilities
PGCIL, WBSETCL, NTPC, State Electricity Boards
Power utilities require insulation testing on HV cables, transformers, and switchgear at commissioning and during periodic maintenance. Earth resistance testing is mandatory at every substation. Transformer oil quality (BDV) testing is performed before energisation and at routine maintenance intervals. Protection relay testing is essential for grid security.
View instruments usedIndian Railways
Traction, Signalling & Telecom, Rolling Stock workshops, OHE teams
Indian Railways is one of the largest users of electrical test and measurement instruments in India. Traction sub-stations, overhead equipment (OHE), rolling stock, and signalling systems all require regular insulation testing, earth resistance verification, and relay testing. CIE instruments have been specified by Railway workshops for decades.
View instruments usedSubstation Commissioning
EPC contractors, commissioning engineers, turnkey project teams
Substation commissioning requires a full suite of T&M instruments — from pre-energisation insulation and earth resistance tests through to protection relay commissioning. EPC contractors rely on instruments that are robust, accurate, and carry traceable calibration. CIE instruments are selected by commissioning teams for their proven field reliability.
View instruments usedIndustry & Manufacturing
Steel plants, cement, mining, heavy industry, process industry
Industrial plants depend on reliable motors, cables, and transformers. Regular insulation testing is the primary tool for preventive maintenance — catching deteriorating insulation before it leads to costly failures. Earth resistance testing ensures equipment safety. CIE instruments are used by maintenance engineers in some of India's largest industrial installations.
View instruments usedTest Laboratories
NABL accredited labs, calibration centres, R&D facilities, academic institutions
Test laboratories require instruments that are stable, accurate, and calibrated to traceable standards. CIE provides calibration records for all instruments in the range — making them suitable for use in NABL-accredited labs and other regulated testing environments.
View instruments usedEPC Contractors
Turnkey substation contractors, cable laying, power plant construction
EPC contractors are responsible for instrument-based acceptance testing at project handover. Their T&M instruments must be certified, calibrated, and fit for purpose. CIE's calibration records and 12-month warranty make the complete range a preferred choice for project commissioning stores.
