Abstract: A trailer-based system and related method are described for efficiently transporting, configuring and deploying a power flow control system, including connection to a power transmission line. The system may include preconfigured modules using bolted attachments, hoist rings and a corona ring structure. Standardized clamps are also used. A plurality of power flow control modules is operable while mounted on the trailer. The power flow control modules are configurable to inject reactive power into the power transmission line.

Abstract: A system and method using thyristors to protect a series-connected Flexible AC Transmission Systems (FACTS) device from surge currents are disclosed. According to some embodiments, the system includes a thyristor connected in shunt with the FACTS device to be protected. The system further includes control circuitry coupled to the thyristor to drive a gate of the thyristor with a direct current (DC) signal and turn on the thyristor in a time span on order of microseconds. The system and method can be used to protect any series-connected FACTS device that is in danger of being exposed to surge current such as a reclose after a deadline.

Abstract: A system, and method of operating the system, for measuring a continuous signal, having at least two transducers for measuring the continuous signal and for each outputting a signal relating to the measured signal. The transducers receive controlling signals and operate in accordance therewith, the controlling signals being transmitted to the transducers along the same transmitting path consisting of no more than two electrical conductors or no more than one optical conductor or consisting of transmitters and receivers for wireless communication. Alternatively or optionally, the signal generator may receive power over two electrical conductors over which the signals are transmitted from the signal generator. The present system is especially useful in audio or in setups performing determination and analysis of vibration, acceleration, velocity or sound.
