FAQs
Q: What are the maximum lengths of 10 kV, 35 kV, and 66 kV cables that this 324 kVA/108 kV unit can support? How should the reactors be configured?
A: For 66kV/300mm² cables, the maximum length is 1,000 m; for 35kV/300mm² cables, the maximum length is 1,000 m. Both configurations use four reactors arranged in a 2-in-series, 2-in-parallel combination. For 10kV/300mm² cables, the maximum length is 3,000 m, using four reactors in a fully parallel configuration.
Q: What scenarios are the 1.5kV, 3kV, and 6kV output settings of the excitation transformer suitable for?Q:WHAT
A: The 1.5kV setting is suitable for testing low-voltage cables with reactors in a fully parallel configuration; the 3kV setting is suitable for testing medium-voltage cables with reactors in a two-series-two-parallel configuration; the 6kV setting is suitable for testing high-voltage transformers/GIS with reactors in a fully series configuration, and can be flexibly switched according to the test voltage.
Q: What are the inductance, withstand voltage, and Q-factor of a single reactor? What is the Q-factor of the entire unit?
A: A single reactor has an inductance of 100 H ±5%, a power-frequency withstand voltage of 27 kV for 60 seconds, and a Q-factor of ≥30; the unit itself has a Q-factor of >50, and with cable load, the Q-factor is >30.
