Definition & Key Features
- Voltage Levels
- Low Voltage Units: 400V (3-phase) / 480V (North American standard).
- High Voltage Units: Common ratings include 6.6kV, 10kV, and 11kV (global standards). Furthermore, it has specialized models reaching 15kV or 35kV for unique applications.
- Core Advantages
- Reduced Transmission Loss: Higher voltage = lower current (P=I²R), in other words, to minimize line losses for long-distance power delivery.
- Industrial Grid Compatibility: Direct integration with factory high-voltage distribution systems, as a result, is conducive to step-down transformers.
- High Power Capacity: Single-unit output ranges from 1200kVA to 5000kVA+ (on the other hand, low-voltage units typically <2500kVA).
Typical Applications
| Scenario | Key Requirement |
| Mines/Oil Fields | Long-distance power supply to drilling/ extraction equipment, as well as reducing cable costs. |
| Large Factories | Direct connection to 10kV on-site grids, as a result, can avoid multi-stage voltage conversion. |
| Data Centers | Moreover, higher efficiency for MW-scale UPS (uninterruptible power supply) demands. |
| Ships/Offshore Platforms | Not to mention high voltage (e.g., 6.6kV) saves space, at the same time, it reduces cable weight in confined areas. |
Key Components
- Generator
- First, check the insulation class: H-grade (180°C) materials to withstand high-voltage breakdown.
- Then, the cooling methods: Water-cooled (high power) or hydrogen-cooled (ultra-large units).
- Voltage Regulation
- AVR (Automatic Voltage Regulator): Precision ±1% fluctuation tolerance.
- Grid Synchronization
- Complies with certified standards for safe parallel operation with grids.
- Protection Systems
- Essential Safeguards: Not only overvoltage, short-circuit, and differential protection, but also some require neutral grounding resistors to limit fault currents.
High Voltage vs. Low Voltage Comparison
| Parameter | High Voltage Genset | Low Voltage Genset |
| Typical Voltage | 10kV | 400V |
| Single-Unit Capacity | 2000kVA~5000kVA+ | 50kVA~2500kVA |
| Transmission Distance | >500m (low loss) | <200m (requires thicker cables) |
| Cable Costs | 30%~50% lower (smaller current) | Higher |
| Maintenance Complexity | High (requires certified expertise) | Lower |
FuDianKang High Voltage Generator Latest Projects
The Above is FuDianKang’s Cummins High Voltage Generator Set KTA38 Diesel Generator for Industrial Power Backup
And recently, FuDianKang exported 2 sets of MTU 10.5KV High-Voltage Generators, and moreover, the 2000KW Diesel Generator Sets Equipped with Parallel Systems and ATS Control.
The MTU 2000kW high-voltage diesel generator sets are powered by German MTU (Mercedes-Benz Power) engines. Additionally, they are paired with a well-known high-voltage alternator such as Stamford or Leroy-Somer. It delivers an output voltage of 10.5kV, not only making it ideal for industrial, energy, mining, and data center applications but also suitable for high-power and long-distance transmissions.
This generator set features high reliability, excellent fuel efficiency, and long maintenance intervals. Furthermore, this makes it suitable for 24/7 continuous operation or as a standby power supply.
Let’s continue. What is a High Voltage Generator Set?
A high-voltage generator set refers to a power generation system with an output voltage significantly higher than standard low voltage (400V/480V). In other words, these units operate at 6.6kV, 10kV, 11kV, or higher, specially designed for high-power supply, industrial facilities, as well as long-distance power transmission.
