Electrical Power Measurements

The Electrical Power Measurements Group maintains standards, provides calibration services, develops instrumentation and testing procedures, and investigates new technology in the area of electrical power measurements. The Group focuses on meeting present and future requirements of the Canadian electrical power industry for precise measurements and in particular develops state-of-the-art instrumentation and measurement techniques including:

• special revenue meters for electric utilities
  
• calibration facilities for equipment such as instrument transformers, active/reactive power and energy meters under sinusoidal/nonsinusoidal waveform conditions, high voltage capacitors, high current resistors and shunts (ac and dc), and high voltage loss measurement systems for transformers and inductive reactors
  
• diagnostic techniques and instrumentation to assess the operating conditions of high voltage apparatus in service,

and provides basic knowledge relating to national and international standards for electrical power measurements and diagnostic and maintenance techniques for high voltage apparatus.
