摘要： The present invention discloses a noise location method and apparatus for reverse power feed line. The method includes: detecting (201) a first noise situation of a subscriber line when there is no reverse power feed (RPF), detecting a second noise situation of the subscriber line when a power feed line of a power supply equipment (PSE) of a user terminal is connected to a power equipment (PE) and a power supply unit (PSU) of a distribution point unit (DPU) and the PSE supplies power, and detecting a third noise situation of the subscriber line when the PSE of the user terminal is disconnected from the PE and the PSU of the DPU and keeps the state of supplying power; and performing comparison on the first noise situation of the subscriber line, and the second noise situation of the subscriber line and/or the third noise situation of the subscriber line, and determining (202) whether a power supply noise emanates from the RPF and affects the subscriber line or not.

摘要： Method and apparatus for measuring an earth fault current in an output circuit of an inverter (INU) operating on the PWM principle and forming alternating-current voltage from direct-current voltage, the output currents (i U , i V and i W ) of which inverter are measured, and which inverter comprises at least two phase switches implemented with power semiconductor components (V 1 - V 6 , D 1 - D 6 ), which switches, controlled by a control unit, connect their own output phases to a positive (+) pole and to a negative (-) pole of a direct-current voltage source such that the phase switches are repeatedly both in different positions and also in the same positions, wherein the results of current measurement during two opposite switch position combinations are recorded in memory, and the earth fault current is calculated by forming a difference of the measurement results of said combinations.

摘要： The invention relates a system for providing information about installation quality of load elements (30). Performance of power distribution systems, such as Power-over-Ethernet (PoE) systems, is depending on the overall system installation performance like quality of the connections (10) between power control devices (20) (e.g. PoE switches) and the powered load elements (30) (e.g. luminaires), Cat5/6 cable quality, cable type, length of the cables, aging of the connections, etc. The proposed system is able to provide feedback and to judge system installation performance at t=0 and over time.

摘要： An inspection apparatus (300), including an extendable structure (302), an inspection probe (304), a drive (316), a sensor (530), and a processor (520). The extendable structure includes an end fixed to the inspection probe and insertable into a gap (110) defined between a first surface (102) and a second surface (104). The extendable structure is configured to maintain physical contact with the first surface as the end transitions across the first surface. The drive is configured to position the inspection probe. The current sensor is coupled to the drive and configured to measure a drive load over a period of time the inspection probe transitions across the first surface. The processor is coupled to the sensor and is configured to receive a signal associated with the drive load corresponding to movement of the inspection probe, and determine an operating condition of the extendable structure based on the drive load signal.
