Latest Patents

Bradford's latest patents include a method and apparatus for measuring electrical parameters using a digital current meter. This device can be used independently or in conjunction with a voltage meter. The current meter features a current sensor that outputs the time derivative of the current flowing through the load being measured. The differentiated current signal is digitally sampled, filtered, and integrated to provide accurate measurements. Additionally, a feedback path is included to eliminate the direct-current component of the current signal, ensuring the integrator remains within range.

Another notable patent by Bradford is a method and apparatus for measuring volt-amperes reactive power. This invention measures true volt-amperes reactive power by sampling instantaneous voltage and current values of an arbitrary waveform. The voltage samples are processed using the discrete Hilbert transform to obtain quadrature voltage samples, which are then multiplied by the corresponding current samples to yield an accurate value for reactive power. This innovative approach can be implemented in software or suitable hardware components.
