Phase verification of power test systems
One aspect of the problem of the measurement of the losses in low power factor devices such as power transformers or power reactors is the verification of the phase angle properties of both the complete system and its various component parts. The use of a digital phase standard as a solution to this...

| description | One aspect of the problem of the measurement of the losses in low power factor devices such as power transformers or power reactors is the verification of the phase angle properties of both the complete system and its various component parts. The use of a digital phase standard as a solution to this and other phase measurement problems is proposed. When a phase standard is synchronized in both phase and frequency, then its precise digital phase shift properties, used in conjunction with passive phase bridges, allow the design of high-power, high-accuracy (better than 0.001), phase verification schemes. Methods using this approach are outlined that use commercially available, easily transportable equipment to provide rapid and accurate phase angle measurements for almost all possible combinations of current and voltage.< > |
