Abstract: A wireless phasing voltmeter transmitting two bits per second includes a reference unit using two audio frequency pulses per second to modulate a radio frequency carrier wave for simplex transmission of phase information to a field unit. The time between the two data bits is proportional to the phase difference between the reference voltage waveform and a first GPS-signal based waveform. The audio frequency of the two audio pulses representing the two data bits points to the frequency of the electric grid, rising when the grid frequency is faster and falling when the grid frequency is slower. A meter probe measures the phase angle of the field conductor against a second GPS generated waveform. Comparison yields the phase angle difference between the field conductor and the reference conductor. The radio frequency simplex data transmission perhaps using a cellphone data link, transmitting lower data rates is more reliable over greater distances.

Abstract: A phasing voltmeter having a dual input AC voltage measuring device in parallel with a series configuration of two high impedance high voltage resistors and two metering resistors. Shielding surrounds and isolates the voltmeter and is connected to the series configuration at a junction between the two metering resistors. The AC voltage measuring device measures the voltage across two voltage lines as well as the exact values of the stray AC capacitive charging currents associated with all high voltage sources. From these previously undesirable stray capacitive charging currents, a math processor in the voltmeter and in contact with two dual input measuring device receives input from between each resistor in the series, determines and displays the actual voltage across the conductors, its origin, the leading phase, lagging phase, phase sequence and phase rotation of the voltages on the AC conductors undergoing testing.

Abstract: A wireless phasing voltmeter determines the phase difference between the voltage carried by a reference electrical conductor and a field conductor. The voltage signal from the reference conductor is detected by a first unit and compared to a precision 60 Hz wave form generated from a first 1 pps GPS signal. The phase difference between the wave form and the reference conductor, represented by nine data bits, is used to modulate a radio frequency carrier wave and transmitted via simplex transmission to a second unit near an electrical conductor in the field. The second unit receives the modulated carrier wave, decodes the phase angle difference and compares it to a second phase angle difference between the voltage on the field conductor and a second precision 60 Hz wave form generated from a second 1 pps GPS signal. The difference between the two phase differences determines the phase of the field conductor.

Abstract: A voltage detector that more accurately measures AC voltage of a voltage conductor by correcting the voltage detected directly by the detector's contact probe to account for the conductor's size and shape. The housing of the detector has plural non-contact electrode sensors spaced apart over its surface for sensing capacitive charging currents in the detector's vicinity. By combining voltages sensed by these electrode sensors to the probe's measured voltage, the detector can correct the contact probe measurement for voltages that bypass the contact probe or other conductors in the vicinity that product their own capacitive charging currents. A microprocessor in the housing of the present detector adds or subtracts sensed voltages depending on whether they are input or output voltages, respectively.

Abstract: A wireless alternating current phasing voltmeter multimeter that uses modular wireless based components in order to provide indications of highly desirable parameters of interest, such as AC voltage, phase rotation, and the number of degrees difference between phases. The use of wireless technology eliminates the cable customarily used to interconnect the test probes and the metering circuitry, which may effectively eliminate the concern regarding the distance separating the power lines that are to be tested. The wireless alternating current phasing voltmeter multimeter has two base modules, but, because of the flexibility of the design, modifications can be readily incorporated into the present invention modules that allow for numerous operational and functional permutations to be implemented in order to meet an individual user's needs including the use of one of the modules as a hand-held base module that can be remotely located away from the electrical power lines (or test points).

Abstract: A passive voltmeter for high voltage transmission lines that accurately measures and displays a wide range of voltages. A d'Arsonval type meter movement is preferably used in conjunction with the voltmeter wherein the scale contains a linear range and a compressed, nearly-logarithmic range. A circuit controls the pointer so that the deflection is linear for a low range of voltages while a high range of voltages is deflected in a compressed manner. The term “compressed” means that the display is scaled in a logarithmic manner although not a true logarithmic function. The circuit comprises one or more parallel branches with a meter movement and a resistor in the first branch; each additional branch, if more than one, contains a resistor and at least one diode connected in series. The additional branches have an increasing number of serially connected diodes so that the turn-on voltage for each branch increases with additional branches, while the resistors contain a decreasing values of resistance for each additional branch. The passive voltmeter comprises a housing internally coated with a conductive material, a high resistance prong extending from the housing, and a meter movement connected to the housing. As the prong touches the line, a capacitive charge is formed with the housing as the first plate and the physical surroundings as the second plate. The meter movement is deflected by the charging current since the current will be proportional to the voltage in the transmission line.

Abstract: A device and method of wrapping an electric cable used for grounding a utility vehicle to minimize its electrical impedance to 60 Hz alternating current. Electrical cable is wrapped around an array of four spools that are arranged so as to form two parallel, closely-spaced planes with the axes of the spools defining the planes. The distance between the spools of each plane is larger than the distance between the planes so that the cable, when wound, forms long, parallel segments. By reversing the direction of the cable and keeping the segments parallel and close to each other, electrical currents induced in these segments cancel each other and keep the impedance in the wrapped cable minimal. Preferably the cable wrapping path begins between the two pairs of spools and continues counterclockwise outside both of the pairs of spools. The path then proceeds between the spool pairs and then clockwise outside of both pairs to the starting point.

Abstract: Power transfer over power lines is indicated using a controller to short power lines briefly near the end of the positive portion of the alternating voltage cycle of a distant power generation source using a silicon-controlled rectifier thereby creating current pulses from the voltage produced by that source and at a frequency consistent with the source's electric system frequency. The pulse can be detected and measured on other parts of the same circuit using a probe. The controller and probe may be used for locating cables in the same electrical circuit, sorting particular cables in the same circuit from others cables, verifying the condition of cables, determining the source and load feeds on the primary side of a transformer from the low side of the transformer, locating unwanted ground faults, and determining the portion of the electrical load provided by each of plural generation plants.

Abstract: A long range wireless phasing voltmeter determines the phase difference between the time-varying voltage carried on a reference electrical conductor and another, field conductor. The voltage signal from the reference conductor is measured by a reference probe and compared by a first unit in communication with that reference probe to a 60 Hz signal generated from a GPS receiver. The phase difference, in the form of a nine-bit, audible signal using frequency shift keying to modulate the carrier frequency, is transmitted to a second unit perhaps miles away. A receiver in the second unit decodes the signal and uses another 60 Hz signal generated from another GPS receiver to re-create and then forward a surrogate of the original reference voltage signal to a meter probe that is measuring the signal on a field conductor. The meter probe can then compare the two signals to determine the phase angle difference.
