摘要： A method and a protection IED for supervising a secondary circuit of an instrument transformer in a power system are disclosed. The instrument transformer is connected to a power system component. The method includes: detecting, by a protection IED which is connected to the secondary circuit of the instrument transformer and protects the power system component, disturbances in a signal from the instrument transformer; and determining whether a failure occurs in the secondary circuit of the instrument transformer, according to both a disturbance detection result from the protection IED and another disturbance detection result from at least one of other protection IEDs. The other protection IEDs include protection IEDs which are connected to other secondary circuits of the instrument transformer or to secondary circuits of another instrument transformer connected to the power system component, and protection IEDs which are connected to other instrument transformers connected to other power system components connected to the same busbar as the power system component is connected to. The secondary circuit supervision solutions provide more reliable and sensitive performance and need very small amount of information to be collected.

摘要： The present invention provides a safer all-around radiation heating assembly than similar traditional heaters. As typical with traditional heaters, a shroud is used to surroundably cover a portable liquid propane tank. To replace the portable liquid propane tank, the shroud must be continuously raised to a predetermined height while a service person accesses the propane tank. There is a danger that if and when the shroud drops, a spark could be created resulting in igniting highly flammable escaped propane gas. The present invention overcomes dangers associated with the traditional heaters by eliminating the spark creation danger and by introducing a ventilation system to allow any leaked propane gas to escape away from the heater.

摘要： A breaker failure protection system for a high voltage direct current, HVDC, circuit breaker is provided. The circuit breaker is arranged for interrupting a DC circuit upon reception of a trip signal. The protection system includes a current sensor, at least one inductor, and a breaker failure detection unit. The current sensor is arranged for measuring a current I(t) through the DC circuit. The at least one inductor is connected in series with the DC circuit. The breaker failure detection unit is arranged for assessing, whether the circuit breaker has failed, and sending, if the circuit breaker has failed, a trip signal to an adjacent circuit breaker. The assessment is based on the measured current. The stability of HVDC grids may be improved by sending, in case of a breaker failure, a trip signal to adjacent circuit breakers. Further, a method of breaker failure protection for an HVDC circuit breaker is provided.

摘要： Technologies are generally described for systems and methods effective to schedule repair (e.g., allocate repair resources, determine a repair sequence, etc.) of a system effected by a large-scale failure caused by a natural disaster, malicious attack, faulty components, or the like. In an example, the system can generate a schedule that indicates amounts of repair resources allocated for repair of specific components of a disrupted system as well as a time or sequence in which the components are to be repaired. The schedule, in some instance, can operate to maximize an amount of restoration, at each stage of a recovery process, relative to the characteristic of the disrupted system. For example, with a communications network as the disrupted system, the schedule can maximize the amount of total traffic flow capacity recovered after respective steps of the recovery process.

摘要： A circuit breaker for protecting a power line. The circuit breaker includes a control unit and a circuit breaking element disconnecting the power line from a power source. The control unit detects a fault on the power line, opens the circuit breaking element, which opening starts a disconnection time interval, injects a test signal into the power line, measures a response, determines an impedance of the power line from the response, analyses the impedance during the time interval based on comparing the impedance with a reference threshold, determines a permanent or a temporary fault based on the analysed impedance, re-closes the circuit breaking element after the time interval if the fault is temporary and keeps the circuit breaking element open after the time interval if the fault is permanent.

摘要： On each draft element of a ring spinning frame, two pieces of short-staple roving from the roving bobbin enter into the draft mechanism to be drafted though a guide funnel in parallel, two pieces of filament are fed from the back of the front roller, and combine with two pieces of roving at front jaw respectively. The drafted two pieces of roving and filament are output from the front jaw and enter into the twisting triangle area to be twisted, and then are wound onto a yarn bobbin to produce yarn. Based on the relative position of the two pieces of roving and two pieces of filament, different yarns can be produced. Furthermore, multi-component yarn, such as core structure, wrapped structure, strand-like structure, can be produced on a ring spinning frame. The structure of yarn can be precisely determined. Special fiber yarn can be produced on traditional spinning frame.
