摘要： A sensor assembly connected between a power line to be monitored and ground as a flexible lead assembly integrated with respective input and output ends as a single encapsulated flexible unit. A V-block (101) and screw clamp (109) are attached to an input circuit (102) which includes a current sensor coil (104) which generates an optical signal and transmits the sample data over a optical waveguide (105). This sample data is received by an output circuit (106) which is connected to ground through connector (107). Circuit (106) is also connected to a resistive element in the form of a resistor chain (103) which spirals around optical waveguides (105 and 110) and connects at the input end to circuit (102) which in turn connects to V-block (101) and thence to the line. The electronic circuits on circuit boards (102) and (106) sample and digitise the instantaneous value of this current from circuit board (102 to 106) over optical waveguide (105) along with the line current sample data. The optical signal(s) are converted to electrical form at the output end. Electronic circuitry on circuit board (106) processes the current and voltage sample data to derive information about the power line such as RMS current and voltage, power flow, power factor and so on and transmits this data in digital form to other equipment via external connector (107).
