Periodic calibration for various reference standards is essential for quality assurance and reliability. GCSPL offers comprehensive calibration services at its permanent lab as well as on-site for various AC power energy measurement and calibration equipment. Traceability of reference equipment is maintained by National and International accredited laboratories. GCXPL is regularly calibrating and certifying Precision Static Energy Standards like
• ZERA Make Reference Instruments like MT3000, TPZ 303 (Class 0.02), MT320 (Class 0.05)
• Radian Make Reference Standard
• Yokagawa Make Power Analyzer
By using Zera MakeThree Phase Reference Standard COM 3003 having an accuracy of 0.01% various Electricity Boards in the country such as TSSPDCL, APEPDCL, TNEB, MSEB, Meter Manufacturers and several other private organizations are availing these facilities to calibrate their Energy Standards.

Various utilities and Private companies need periodic calibration of energy meter and correct accounting of energy meters. Our teams, equipped with reference meter, can test meter at customer premises and hand over NABL calibration certificate on the spot. This reduces down time of the industry.
GCSPL is regularly calibrating and certifying Static Energy Meters of 0.2S Class accuracy of various companies like
