A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power. An Automatic Transfer Switch (ATS) is often installed where a ...
D-ATS-P (Digital ATS-P) (Used by Odakyu Electric Railway, not compatible with JR ATS-P) T-ATS (formerly used on Toei Mita Line , similar to Tobu ATS, replaced by ATC-P) Tobu ATS ( TSP ) (Used by Tobu Railway , except for the section of track between Ikebukuro and Ogawamachi on the Tobu Tojo Line )
D-ATC indicator used on the E233 series trains. The digital ATC system uses the track circuits to detect the presence of a train in the section and then transmits digital data from wayside equipment to the train on the track circuit numbers, the number of clear sections (track circuits) to the next train ahead, and the platform that the train will arrive at.
When an ATM circuit is set up each switch on the circuit is informed of the traffic class of the connection. ATM traffic contracts form part of the mechanism by which quality of service (QoS) is ensured. There are four basic types (and several variants) which each have a set of parameters describing the connection.
The "Firetrol" branch of ASCO provides power transfer switches, controls, and alarms for fire suppression. ASCO's headquarters is located in Florham Park, New Jersey . With over 1400 employees and 500,000 square feet of manufacturing floor space, it is the world's largest manufacturer of power transfer switches.
The fast operation of CML circuits is mainly due to their lower output voltage swing compared to the static CMOS circuits, as well as the very fast current switching taking place at the input differential pair transistors. One of the primary requirements of a current-mode logic circuit is that the current bias transistor must remain in the ...
In Electrical Engineering , a static synchronous compensator (STATCOM) is a shunt-connected, reactive compensation device used on transmission networks. It uses power electronics to form a voltage-source converter that can act as either a source or sink of reactive AC power to an electricity network.
When the choke circuit is open magnetic flux in the receiver's primary coil is able to induce a voltage in the receiver's secondary coil which in turn triggers an action in the locomotive. When the circuit is closed the choke eliminates the magnetic field and the voltage induced by it allowing the locomotive to pass without activation.
