FAQ
- What does a GGJ cabinet do?
- GGJ provides low-voltage reactive-power compensation to improve power factor, typically for 130–600 kVA three-phase transformers; rated 0.38–0.66kV, 1–600 kvar, 50Hz.
- Which compensation mode do I need?
- Standard for fixed loads; H mixed, F split-phase for unbalanced loads, D dynamic for fast-varying loads, W outdoor for outdoor use.
- How much kvar should I add?
- Start from roughly 20–30% of transformer kVA to reach a 0.9–0.95 power factor, then confirm with a site measurement. See the compensation selection guide.
- Is the switching automatic?
- Yes — an automatic power-factor controller with contactor or thyristor switching steps the capacitors to track the load.
