VZIMAN Z-type Grounding Transformer Solution: Eliminating Grid Risks in Ungrounded Systems​
1. Solution BackgroundIn 6kV~36kV distribution networks, delta-connected transformer windings lack a neutral grounding point. VZIMAN® Grounding Transformer addresses this by creating an artificial neutral through Z-type winding topology. This design prevents critical risks during single-phase ground faults, including: Overvoltage hazards(>2.5x line voltage in ungrounded systems) Persistent fault currentscausing equipment degradation Protection device failuredue to insufficient fault c

Intelligent High Voltage Outdoor Disconnector Solution for Vietnam's Distributed PV and Storage Projects
1. Project BackgroundDistributed photovoltaic (PV) and energy storage projects are developing rapidly in Vietnam and Southeast Asia, but face severe challenges:1.1 Grid Vulnerability: Vietnam's grid experiences frequent fluctuations (especially in northern industrial zones). In 2023, coal power shortages caused large-scale blackouts, resulting in daily losses exceeding USD 5 million. Traditional PV systems lack rapid isolation capability, making them prone to equipment damage and safety incident

Intelligent High-Voltage Gas-insulated Switchgear (HV GIS) Solutions
1. Challenges1.1 HV GIS Structural ConstraintsDue to the highly integrated and enclosed structure of HV GIS equipment (often likened to a "black box"), internal issues such as contact loosening and poor electrical connections are difficult to detect using conventional methods. For example, statistics from Xinjiang Changji Power Supply Company indicate that 29% of HV GIS equipment failures originate from poor contact connections. Traditional approaches rely on manual disassembly or empirical judg
