GENERATED NOISE IN IGNITION SYSTEMS High-frequency electromagnetic interference (EMI), commonly referred to as Radio Frequency Interference (RFI), generated by a gasoline engine ignition system, comes primarily from the high-voltage side of the circuit. Ignition systems produce sparks at the coil where the battery voltage is converted into high voltage pulses, at the distributor where the high ...

Abstract A set of remote electric control disconnection device for high-voltage line with strong adaptability, easy operation, and high safety has been designed to address the problems multiple spans, wide coverage, difficulty in coordinating power failure construction crossing operation. The design process aimed reduce weight improve reliability mechanical structure, conducted computation simu...

In static load tests vibrating wire strain gages are generally used. The advantage of vibrating wire sensors over more conventional electrical resistance or semi-conductor types lies mainly in the sensor output, which is a frequency rather than a voltage or resistance. The frequency output is easier to transmit over long cables and is unaffected by voltage drops such as those which can be broug...

In this paper, an efficient blind equalization with two-stage single/multilevel modulus and decision directed (DD) least mean square (LMS)-like algorithm is proposed for high-order QAM (64/256/1024QAM) cable modem systems. In wire-lined cable systems, it seems that the cable channel may display a nearly invariant multi-path effect over a considerable time, and then the blind equalizer can have ...

The view of line-bound energy industries as "natural monopolies" has changed considerably during recent years upon the perception that each of the industries could be seen as a combination of different functions. The natural monopoly perception for each function has been reassessed, resulting in many cases in transportation functions such as transmission and distribution as well as dispatch rem...

This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. This paper provides high frequency models ...

The National Grid Company Plc. is responsible for the maintenance of the high voltage electricity transmission network in England and Wales. It must plan maintenance so as to minimize costs taking into account: location and size of demand, generator capacities and availabilities, electricity carrying capacity of the remainder of the network, i.e. that part not undergoing maintenance. Previous w...
