The AC narrow gauge lines use voltages of 66 kV, 77 kV, 110 kV, and 154 kV AC, converted to 20 kV AC using a transformer. In general, these are done very simply, with the transformer driving the feeder wire through a circuit breaker, and no other systems. However, the modern DC system uses solidstate electronics to perform the AC to DC conversion.

Fortunately there are readily available solutions to this problem. Many high power circuits today are controlled by low voltage, low current circuits such as microprocessors, using opto electronic devices such as Opto−Triacs, Opto−Thyristors and Solid State Relays to isolate the low and high power circuits.

A completely new generation of circuit breakers, contactors, overload relays and load feeders in seven sizes up to 250 kW is ready for use. The benefit of the modular system lies in its modular setup of the components across all sizes.

828 Solid State Relays Technical Information Solid State Relays Technical Information Glossary Terms Meaning Circuit functions Photocoupler Phototriac coupler Transfers the input signal and insulates inputs and outputs as well. Zero cross circuit A circuit which starts operation with the AC load voltage at close to zerophase.

Direct Burial of Cables or Conductors. Underground feeder cables, labeled UF, can be buried without additional protection from conduits because they have a tough jacket designed for burial. Bury UF cables 24 inches below the soil surface, and 18 inches deep when protected by 2 inches of concrete.

Electrical Relay. Electrical Relays can also be divided into mechanical action relays called "Electromechanical Relays" and those which use semiconductor transistors, thyristors, triacs, etc, as their switching device called "Solid State Relays" or SSR's.

This type of construction facilitates easy removal and replacement of the relay(s) in the event of failure. Aside from the ability to allow a relatively small electrical signal to switch a relatively large electric signal, relays also offer electrical isolation between coil and contact circuits.

Construction. The construction and working of the vibrating contact regulator is somewhat similar to that of the carbon pile type. The operating coil, which is arranged in the same way in both the regulator systems, is supplied with rectified current from the alternator output.
