Experiments Covered
- DC machines: DC generator and DC shunt motor, starting by series resistance or reduced voltage, reversing, and speed control by armature resistance, field resistance or lower armature voltage.
- Single-phase transformer: ratio K, no-load test (I0, P0, U0), short-circuit test (UK, IK, RK) and load characteristic.
- Three-phase transformer: winding polarity and connection group.
- Three-phase asynchronous motor: stator resistance, no-load and short-circuit tests with characteristic curves, parameter calculation and mechanical characteristics.
Machine Rail, Loads and Protection
The machines sit on a stainless steel guide rail over a 20 mm steel plate, with an optical code-disc speed system and digital tachometer. A corrected DC dynamometer measures the output power of the prime mover. Loads come from three-phase adjustable resistors (three groups of 90 Ω × 2 at 1.3 A and three of 900 Ω × 2 at 0.41 A) and a light-box load. If the AC output sees over-current or a direct short circuit, it raises an alarm and cuts the supply, and a timer-alarm recorder logs alarm times. The table top is fire-, water- and wear-resistant high-density board.
