NewTrend · cabinet static var generator
Product overview
NewTrend Y-SVG-Cabinet integrates AC distribution, SVG power modules and a monitoring system in a floor-standing cabinet for dynamic reactive-power compensation. The family covers five voltage platforms from 220V to 800V, with voltage-dependent cabinet capacity ranges from 50 to 900kvar. Each cabinet is configured to the required capacity within its voltage-platform range.

Operation
- The cabinet connects in parallel with the load and combines AC distribution, SVG modules and system monitoring.
- The 220–690V platforms support reactive compensation or reactive plus three-phase unbalance compensation. The 800V platform is 3P3W with reactive compensation only.
- The published capacities are platform ranges, rather than a list of discrete orderable steps. Exact capacity, module arrangement and cabinet outline are confirmed for the installation.
Typical applications
- Industrial and commercial reactive-power compensation systems
- Centralized cabinet installations serving variable reactive loads
- Three-phase load-balancing applications on supported 220–690V platforms
