Electrical Testing & Instrumentation Authority
Calibrated Engineering Validation for LT & HT Systems up to 132 kV and Above
Electrical safety cannot be verified through observation alone. It requires calibrated measurement, technical validation, and structured engineering analysis.
Elion Technologies & Consulting Pvt. Ltd. conducts in-house electrical testing and diagnostics using NABL-calibrated instruments, ensuring traceable, defensible, and technically validated audit outcomes.
All testing is performed by Elion’s engineering team without subcontracting.
NABL-Calibrated Instrumentation & Traceability
All instruments used during Electrical Safety & Technical Compliance Audits are calibrated annually through NABL-accredited laboratories.
Audit reports include:
- Calibration certificate copy
- Last calibration date
- Validity / expiry date
- Traceability reference
This ensures measurement credibility and regulatory defensibility.
Elion conducts structured technical testing for both LT and HT installations.
Testing capabilities include:
- Primary injection testing
- Secondary injection relay testing
- Breaker timing verification
- Relay functional validation
- IR thermographic scanning of panels and switchyards
- Acoustic imaging for partial discharge detection in switchgear
- Protection coordination validation
HT systems up to 132 kV and above are evaluated using engineering-grade instruments and ETAP-based analytical modeling where required.
Relay Testing & Protection Validation
Protection reliability is validated using Omicron relay testing kits.
Testing includes:
- Time-current curve validation
- Relay pickup and trip verification
- Clearing time analysis
- Selectivity validation
- Curve coordination cross-check
Relay curves are verified against ETAP-based fault modeling and system load characteristics to ensure coordination integrity.
Arc Flash Engineering Validation (IEEE 1584 & NFPA 70E)
Arc flash exposure assessment includes:
- Short circuit current modeling
- Incident energy calculation
- Working distance determination
- Arc flash boundary calculation
- Restricted and Limited Approach Boundaries identification
- PPE category recommendation
- Arc flash label generation
Labels are provided as part of audit deliverables.

Power quality assessment includes structured measurement of:
- Voltage & Current THD
- Harmonic spectrum profiling
- Voltage imbalance
- Load imbalance
- Flicker
- Transients & surges
- Power factor monitoring
- Demand profile logging
- RCCB & ELCB functional testing
Analysis is conducted using professional-grade power quality analyzers including Fluke 1777, 435-II and equivalent systems.
Data is interpreted against applicable standards and operational limits.
Structured earthing validation includes:
- 3-point and 4-point earth resistance testing (based on site conditions)
- Earth continuity testing
- Separate lightning arrestor earth measurement
- Ground grid integrity evaluation
Testing ensures compliance with IS 3043 and applicable grounding requirements.
Thermal diagnostics are conducted using FLIR, Testo, and Fluke thermal imaging systems.
Applications include:
- Panel hotspot detection
- Busbar overheating identification
- Termination loose contact detection
- Transformer thermal anomaly detection
- Switchyard joint inspection
Thermal image annexures are included in final audit reports.
Why In-House Testing Matters
All testing and validation activities are conducted by Elion’s own trained engineering teams.
No subcontracting ensures:
- Technical consistency
- Calibration traceability
- Controlled methodology
- Accountability
- Data integrity
This strengthens reliability of audit findings and compliance documentation.
