Industries & Applications
CIE instruments are in daily use across India's critical infrastructure — from generating stations to rolling stock workshops.
Power Utilities
PGCIL, DVC, 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.
CIE Instruments Used
- CIE/444, CIE/666 — insulation testers for HV cables and equipment
- CIE/777 series — motorised HV insulation testing
- CIE/222M — earth resistance and soil resistivity
- CIE/7000 series — transformer oil BDV testing
- RTS-33 — three-phase relay commissioning
- DIT-2500, DIT-5000 — digital insulation testers
Indian 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.
CIE Instruments Used
- CIE/666 HV insulation testers for traction equipment
- CIE/444 for rolling stock and OHE insulation checks
- CIE/222M for earthing at traction sub-stations
- RTS-33 and RTS-5A for protection relay testing
- PSI-1, PSI-2 for 3-phase supply phase sequence verification
Substation 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.
CIE Instruments Used
- Full insulation tester range for pre-energisation checks
- CIE/222M earth tester with full kit
- CIE/7000 series for transformer oil quality
- RTS-33 / RTS-5A / RTS-5 for relay testing
- MR-253A for contact resistance of breaker contacts
Industry & 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.
CIE Instruments Used
- CIE/444 insulation testers for motors and cables
- CIE/555 compact insulation tester for routine checks
- DIT-5005, DIT-2500 digital insulation testers
- DCM 2250 TR, DCM 5410 TR clamp meters
- DM 235, DM 321T multimeters
- MR-253A micro-ohm meter for motor winding resistance
Test 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.
CIE Instruments Used
- DIT-2500, DIT-5000 for precision insulation measurement (DAR, PI)
- MR-253A bench-type micro-ohm meter
- DET-2000 digital earth resistance tester
- CIE/5050A HV test set for dielectric withstand
- CIE/7000 series for oil BDV testing to IS standards
EPC 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.
CIE Instruments Used
- CIE/444, CIE/666, CIE/777 — commissioning insulation testing
- CIE/222M — substation earthing acceptance tests
- CIE/7000 — transformer oil quality before energisation
- RTS-33 — protection relay commissioning sign-off
- CIE/5050A — HV withstand tests on cables and switchgear
