Introduction

The integration of medium voltage transformers, specifically within the range of 10kV-35kV, is becoming increasingly important in solar energy systems. These transformers play a critical role in stepping up voltage levels for efficient transmission and distribution of solar energy, aiding in the seamless incorporation into national grids.

Key Benefits of 10kV-35kV Transformers in Solar Systems

The utilization of 10kV-35kV transformers in solar installations offers multiple advantages:

• Enhanced Energy Efficiency: By elevating the voltage, these transformers minimize power loss over long-distance transmission.
• Grid Compatibility: They ensure that generated solar energy can be efficiently fed into the grid at appropriate voltage levels.
• Cost-Effectiveness: Reducing current by increasing voltage helps in decreasing the diameter and cost of cabling infrastructure.
• Improved Voltage Regulation: They help maintain voltage stability against fluctuations, enhancing power quality in distributed networks.

Technical Specifications

Standard 10kV-35kV transformers for solar applications come with various technical specifications:

• Voltage Levels: Input voltages most commonly available at 380V or 480V, stepped up to levels between 10kV and 35kV.
• Capacity: Typical transformer capacities range from 250kVA to 5MVA, depending on installation size.
• Frequency: Operate at a standard frequency of 50Hz or 60Hz.
• Insulation Class: Up to Class H (180°C) for handling high operating temperatures.

Numerical Analysis and Performance Metrics

Analyzing the performance of these transformers includes several crucial metrics:

• Efficiency: Many 10kV-35kV transformers achieve efficiencies of over 98%, crucial for minimizing energy losses.
• Load Losses: Exemplary designs register load losses as low as 1.0% at full load under standard conditions.
• No-Load Losses: No-load losses are often reduced to less than 0.3% to enhance idle state efficiency.
