Precision On-Site Calibration
Calibration is not just a check; it is the fundamental engineering process of verifying technical accuracy against National Accreditation Board Laboratories. At Kandha Kadaksham, we bring high-precision laboratory standards directly to your industrial site.
Advanced Technical Verification
Our specialized engineering team utilizes portable reference standards to ensure your critical electrical assets maintain absolute precision without the need for equipment removal.
Voltage Transformer (On-Site)
On-site calibration of Voltage Transformers up to 33 kV as per IS 16227 and IEC 61869. We verify ratio error and phase angle error for accuracy classes 0.2, 0.5, and 1.0, ensuring reliable performance for metering and protection systems. Testing is conducted using AITTS Plus with standard reference PTs, with controlled voltage injection to ensure accuracy without stressing insulation.
Current Transformer (On-Site)
On-site calibration of Current Transformers up to 33 kV as per IS 16227 and IEC 61869. We perform primary injection and secondary testing to verify ratio error, phase displacement, and burden performance for accuracy classes 0.2S, 0.5S, and 1.0. Testing up to 2500 A ensures accurate measurement under real load conditions using AITTS Plus with standard reference CTs.
Energy Meter (On-Site)
End-to-end verification of the metering chain. We specialize in HT (High Tension) and LTCT (Low Tension Current Transformer) meter calibration, alongside Whole Current meters, to ensure absolute revenue integrity and audit-ready compliance.
ISO/IEC 17025 Compliance
Revenue Assurance
Technical Revenue Integrity
Beyond basic measurement, we protect your bottom line by ensuring every unit of energy is accounted for correctly across complex industrial distribution networks.
Industrial Metering (HT/LTCT)
High Tension (HT) and Low Tension Current Transformer (LTCT) systems represent the highest financial stakes in industrial facilities. Our on-site verification confirms the precision of the entire metering loop, from primary sensors to digital readout.
Primary CT/PT Injection
All HT Consumers need Yearly/Periodic Calibration and Testing of instrument Transformers up to 33kV as per IS 16227 (Part-1 to 3) and IEC 61869 for 0.2, 0.5 and 1.0 Class accuracy of various type Voltage Transformers.
For 0.2 S, 0.5 S and 1.0 Class of accuracy for Current Transformers by using ELTEL Make, Automatic Instrument Transformer Test Set (AITTS plus) and Moon Light Electricals Make Standard Potential Transformers and Current Transformer.
The AITTS by ELTEL integrates precision measurement modules, programmable voltage and current sources, and a user-friendly software interface for data acquisition, control, and report generation.
