SOLENOID GP-SHUT-OFF 5N7194 - Caterpillar

suppression:Reduce the cause of radio frequency interference.regenerative power:Power that works against the primary power.reset:To put a switch in a ready condition.saturable reactor:Acts as a valve, as load changes, valve opens or closes to give more or less current to the rectifier.reciprocating:Movement in a straight line first one direction then the other.residual magnetism:The characteristic of a magnet after removal of excitation.saturated:Magnetized to the point where an increase in current will give no increase in magnetic force.satisfactorily:Correctly.SCR:Silicone Controlled Rectifier (semiconductor). selinium (Se):A metallic (like metal) element the with electrical characteristic of being a semiconductor.semiconductor:Components like, transistors, diodes, thyristors, etc. Has electrical characteristics between a conductor and insulation.short:Any connection between two or more components that is not desired.shutdown:When the engine is stopped either automatically or manually.simultaneous:At the same time.solid-state:An electronic component with no moving parts.surge:A sudden increase in voltage or current.tap:Connection to get power from a circuit.tested:When a test has been made.transient peak voltage:A high voltage condition for a short time period.turn-on:To start, as current flow through the controlled rectifier; to activate.voltage droop resistor:Variable resistor for control of voltage change from full load to no load.voltage level resistor:Gives wider range of voltage control.voltage level rheostat:Control for adjusting voltage output level.windings:Layers of wire on a core.wiring:The wires of a circuit.wound:Circled.Identification
TYPICAL SRSE REGULATOR
1. Exciter reactors.All Statically Regulated Statically Excited (SRSE) generators have three large exciter reactors as a part of the regulator assembly.The generator serial number, on the nameplate, tells four things about the generator:1. The first group of numbers is the approximate kW rating on 60 cycle generators. On 50 cycle generators it is usually one less than that for 60 cycle generators.2. The letter S is the symbol for Caterpillar Statically Regulated Statically Excited generator.3. The next letter gives an indication of the voltage rating. See chart. 4. The last group of numbers is the actual serial number of the generator in its kW and voltage rating. If a generator is connected to give performance different from that shown on the nameplate, a new nameplate should be installed on the generator. Mark the new nameplate to show the present method of connection and rated capacities.The chart that follows gives the basic characteristics of each SRSE generator. Principles Of Operation

Relay N.C.The Statically Regulated Statically Excited Generator gives improved performance and longer service life by applying a method of excitation which is controlled by an automatic voltage regulation system that contains no moving parts. The generator voltage buildup system uses only one moving part; a relay, which operates only when the generator is started or shut down.The generator is constructed with the armature coils wound on the stator (E) and the field coils wound on the rotor, designated in the wiring diagram as the rotating field (F). The field coils are
