The following studies can be made:
- Measurements of characteristic data, resistance, reactance and capacitance of a line.
- As transmission line: Measurement of voltage drop and losses for different loads.
- For two-phase and especially three-phase short circuit measurements with two three phase transformers, one at each end.
- For single-phase and two-phase earth fault measurements.
The network model can be used to complete a series of experiments with transmission lines. Those listed and described in detail in the instruction manual include:
Characteristic data of the line
- Voltage drop on the lines
- Short circuit tests
- Earth fault
