Mobile Testing Lab

Mobile Testing Lab    

Mobile test laboratory is to measure ratio and phase angle errors of installed instrument transformers comprising of; current transformers, potential transformers and capacitive voltage transformers. This measurement when combined with the accuracy measurement of energy meters can help in determining the actual energy transmitted. It is important to make the accuracy measurement of the complete measuring arm for determining the quantum of actual energy transmitted. It has been observed that nearly 15% of the installed instrument transformers do not meet the specified accuracy levels thus energy metering in itself is defaulted causing huge revenue loss for the concerned utilities.
