Synchronous Machines Test System

The equipment shall consist of an educational synchronous three-phase electrical machine designed for practical training and experimentation on the operating principles, characteristics and connections of synchronous machines.

·         The machine shall be based on an industrial-type electrical machine suitably adapted for educational and laboratory use.

·         The winding terminals shall be brought out to 4 mm safety sockets mounted on a robust metal housing.

·         A clear electrical diagram shall be provided on the unit to facilitate understanding of the internal winding configuration and electrical connections.

·         The machine shall be suitable for studying the operating principles and winding connections of synchronous three-phase machines.

·         The unit shall be supplied with the required coupling accessories, including a half coupling joint and necessary fastening hardware for connection to compatible training equipment.

Field Regulator Rheostat

·         Description: Precision single-resistor educational rheostat designed for connection in series with the field excitation winding of AC synchronous machines or DC machines to adjust and control excitation fields.

·         Versatility: Can additionally be utilized as a small single-phase resistive load or for controlling small AC and DC currents in laboratory experiments.

·         Enclosure & Connections: Housed in a standard protective enclosure featuring a printed electrical reproduction on top and integrated 4( mm) safety plugs for secure and reliable circuit connections.

·         Current & Power Ratings: Sized appropriately for continuous educational laboratory utilization with clearly indicated power and resistance values or nominal current limits.

Educational Paralleling Board

·         Description: Specialized educational training unit designed to facilitate the paralleling of two three-phase AC generators, or one generator and an electrical grid line.

·         Operational Principle: Compares incoming voltages and frequencies to evaluate and indicate compatibility concerning phase sequence, voltage values, and phase angles prior to safely connecting the two sources.

·         Synchronization Methods: Supports traditional synchronization procedures such as the "lamps bright" or "lamps dark" methods utilizing an integrated three-lamp configuration (one lamp per phase).

·         Protection & Circuit Configuration: Equipped with a dedicated 6.3( A) fuse on each phase line, an ON/OFF control switch, and clearly marked terminal sections for alternating current sources and mains connections via safe interconnection points.
