摘要： An average current value that is the average value of current values is found by connecting a detection resistor in parallel to two terminals that are the object of measurement, measuring the current value that flows in the detection resistor, and subjecting the current value to time-quadrature, and further, dividing the current value that follows integration by the integration time. The average current value is converted to a digital signal and sent to an arithmetic means (processor). The arithmetic means calculates the voltage value across the two terminals from the average current value and the resistance value of the detection resistor.

摘要： A differential current measuring module is composed of a housing that encases a current transformer core and a printed circuit board, the current transformer core surrounding a line duct of the housing and having at least one secondary winding. The differential current measuring module is characterized in that in the line duct, at least one primary conductor is led out on a top side of the housing to be connected to an external electrical feed line and whose other end protrudes out of a bottom side of the housing and is provided with a solder terminal. The principle idea is based on continuing the electrical line to be monitored, in sections, as a primary conductor in the effective area of the current transformer core so as to advantageously arrive at a differential current measuring device whose integration is constructionally simple and which offers an uncomplicated connecting option.

摘要： A voltage gradient detector provides notice when a potentially hazardous voltage gradient is present in water, employing at least one pair of spaced-apart electrodes connected to an LED. The electrode spacing is selected such that, when exposed to a sufficiently large voltage gradient, the voltage between the electrodes causes activation of the LED. The LED can provide visual illumination, or can be a part of a switching device such as a photoMOS relay that in turn activates an alarm device such as an audible sounder or a high-intensity light. Sensitivity in multiple directions can be attained by employing a pair of LEDs between the electrodes, and by employing three pairs of electrodes and associated LED pairs, with the pairs of electrodes being spaced apart along substantially orthogonal axes. These pairs may be discrete or may share an electrode in common.
