Voltage Transformer ungrounded systems JDZX11-20G
- Intro：Epoxy resin cast transformers designed for special voltage levels and ungrounded systems differ mainly in the residual voltage winding function and high environmental adaptability, making them suitable for applications requiring insulation monitoring. When selecting, it is necessary to confirm the system grounding method and whether zero-sequence voltage output is needed. The JDZ(X) model can provide open delta voltage output for system insulation monitoring (such as ground fault alarms), a function not available in ordinary transformers. Voltage level compatibility: Specifically designed for 11-20kV ungrounded systems, with insulation requirements higher than those of ordinary 10kV transformers. Environmental Adaptability (G): If "(G)" represents the plateau type, it possesses characteristics such as cold resistance and UV resistance, making it suitable for special environments.
