摘要： Isolated capacitance line voltage sensing is provided that avoids metal-to-metal contact for voltage sensing of a power signal present on a power wire. An external conductor is positioned by the power wire, creating a capacitor with the power wire conductor, insulation, and external conductor. The capacitance is used to measure the electric field, indicating a voltage level for the powered wire. The impedance mismatch caused by the capacitance is transformed. The impedance transformation circuit may be integrated with the external conductor, allowing voltage sensing by a voltage meter having a lower input impedance. A manual or automatic calibration circuit may be provided to ensure the measured voltage represents the actual voltage on the power wire.

摘要： A system and method is provided for qualitative analysis of baseband building automation networks. The system may include a processor configured to carry out a plurality of tests on a serial communication network that includes at least one field device that carries out building automation communications on the network. A first test may include: transmitting a series of queries for devices on the network, in which the queries are transmitted at incrementally lower transmission signal levels until message loss is detected; and determining a first lower signal level at which transmissions of queries occur without message loss on the network. In addition, the processor may be configured to determine and output on a display device at least one classification of the relative quality of the network with respect to at least one predetermined scale of relative network quality based at least in part on the first lower signal level.
