On-Line Filter System
TP2EC

On-line Oil Filtration For Load Tap Changers,

Regulators and Circuit Breakers

The TP2EC is designed for permanent mounting on electrical apparatus to remove carbon and other contaminants from insulating oil without interrupting service. This unit helps prevent premature failure by keeping the dielectric strength of the oil high.

BENEFITS

• Maintains consistent high oil dielectric strength
  
• Extends maintenance/inspection intervals
  
• Reduces contact wear and coking
  
• Decreases contact erosion in LTCs via reduced re-strikes during tap changing

APPLICATIONS

The Velcon TP2EC is recommended for installation on apparatus that meet the following criteria:

• Perform a high number of operations
  
• Exhibit consistent sludging conditions
  
• LTCs that have a high tap-to-tap voltage difference
  
• Require frequent attention
  
• Are hard to take out of service for maintenance

FEATURES

• All components mounted inside a vented NEMA 4 enclosure
  
• Easy cartridge change due to spin-on design
  
• Built-in pressure relief bypass on pump protects filter from over pressurization when filter is plugged
  
• Fused on/off disconnect switch
  
• Economical design
  
• Pressure gauge indicates when filter cartridge needs changing
