LTC Filtration Systems:

The Load Tap Changer Filtration System (LTCFS) was developed to meet the Electric Utility industry’s need to reduce the overall operational and maintenance costs of Load Tap Changers without sacrificing system reliability. Continuous online filtration of dielectric oil has proven to be a cost-effective means of combating problems associated with LTCs, and transformers retrofitted with our LTC Transformer Oil Filtration System will obtain the following benefits:

·        Maintain High Dielectric Strength

·        Extended Maintenance Intervals

·        Reduced Contact Wear & Coking

·        Extended Oil Life

·        Reduced Contact Erosion

FEATURES

• Flow Rates Ranging from 1 to 15 GPM with 6 GPM standard
• High Efficiency Particulate / Carbon Removal Filter Element composed of microglass media rated Beta >200 – can remove particles as small as ½ micron in single pass
• Water Removal Element capable of removing up to 0.25 gallons of water
• Differential Pressure Gauges for Positive Indication When Filter Elements Need To Be Changed
• Variable Operation allows for System to be run continuously or at 1-4 intervals per day via solid state timer
• Automatic Safety Shut-Down & Isolation if a leak is detected
• Standard Voltage of 120VAC, Single Phase, 60Hz
• Two 0-60 PSID Gauges to visually see differential pressure between filters
• Two oil sample valves for quick and convenient oil analysis
• 
  

RECOMMENDED FOR INSTALLATION ON LOAD TAP CHANGER TRANSFORMERS THAT:

• Operate Near Their Top MVA Rating
• Have High Contact Wear
• Perform At Peak Capacities
• Have A Relatively Small Volume of Insulating Oil
• Experience High Maintenance Costs
