Understanding Insulation Oil Withstand Voltage Standards for Different Voltage Levels

Latest company news about Understanding Insulation Oil Withstand Voltage Standards for Different Voltage Levels

Insulation oil plays a critical role in maintaining the safety and performance of electrical equipment by preventing electrical breakdown. Selecting oil that meets the appropriate withstand voltage standards helps ensure reliable insulation performance. Here’s an overview of the voltage withstand requirements for various levels of insulation oil.

1. Why Withstand Voltage Standards Are Important

Withstand voltage standards are benchmarks that indicate the voltage level an insulation oil can safely withstand without electrical breakdown. Meeting these standards helps prevent equipment failure, minimizes maintenance, and ensures stable operation.

2. Withstand Voltage Standards Based on Voltage Levels

The insulation oil withstand voltage standards vary by the operating voltage of the equipment:

  • For Equipment Below 15KV

    • Before Operation: Oil should have a withstand voltage value of at least 30KV.
    • During Operation: The minimum withstand voltage should be 25KV.
    • Purpose: This helps ensure basic insulation performance for low-voltage equipment.
  • For Equipment at 15KV - 35KV

    • Before Operation: Oil should withstand at least 35KV.
    • During Operation: The minimum withstand voltage is 30KV.
    • Purpose: These values provide increased insulation for moderate voltage equipment.
  • For Equipment at 66KV - 220KV

    • Before Operation: Minimum withstand voltage should be 40KV.
    • During Operation: The minimum withstand voltage should remain at 35KV.
    • Purpose: Enhanced insulation requirements protect against higher voltage demands.
  • For Equipment at 110KV - 220KV

    • Before Operation: Withstand voltage should be 40KV.
    • During Operation: Minimum withstand voltage should remain at 35KV.
    • Purpose: Higher standards reduce the risk of insulation breakdown in high-voltage systems.
  • For Equipment at 330KV

    • Before Operation: Oil withstand voltage should reach at least 50KV.
    • During Operation: The minimum withstand voltage should be 45KV.
    • Purpose: Ensures robust insulation to handle very high voltage levels.
  • For Equipment at 500KV

    • Before Operation: Minimum withstand voltage should be 60KV.
    • During Operation: Oil should withstand at least 50KV.
    • Purpose: This provides the highest level of insulation for ultra-high-voltage equipment.

3. How to Use These Standards for Selection

When selecting insulation oil, use these voltage standards to match the oil’s withstand voltage capability with the equipment’s operational requirements:

  1. Identify Equipment Voltage: Start by knowing the voltage rating of the equipment requiring insulation oil.
  2. Match the Withstand Voltage: Choose oil that meets or exceeds the voltage standard both before and during operation.
  3. Consider Long-Term Operation: Oils should ideally have a margin above minimum requirements to accommodate aging and degradation over time.

Summary

By choosing insulation oil that meets these withstand voltage standards, technical and procurement teams can ensure that equipment runs reliably, reduces maintenance needs, and operates safely at various voltage levels.
