Significance of LF & HF Voltage, Current, Phasor Measurement Unit and Microwave Metrology of CSIR-NPL on Scientific and Industrial Growth

The LF & HF voltage, current and microwave metrology section of the CSIR-National Physical Laboratory plays an imperative role in the metrological investigations in the country as it follows the lawful obligations of the NPL charter of developing and maintaining national standards of HF voltage, LF voltage and current, phasor measurement unit and microwave power parameters. For over three decades, the section has been religiously dedicated to performing national obligations and delivering national calibration, testing and measuring services. Still, there is inadequate awareness, insight and perception related to the role of metrological traceability, calibration and measurement capabilities (CMCs) to the clients, academia, industries and government laboratories. Hence there is a dire need to educate and provide the required information to the end users. Keeping this in mind, this paper provides necessary details of the facilities, technologies and CMCs of the section to the common masses. The International Bureau of Weights and Measures (Bureau International des Poids et Mesures) and Asia Pacific Metrology Programme key/supplementary comparisons are also described in the paper, which has helped the group improve and attain greater heights.
