Core offering

Power Substation Services (PSS) provides nationwide field services for substation, power, and GSU transformers up to 1300 MVA and 765 kV. Its expert crews install, vacuum-fill, electrically test, reclaim oil on energized units up to 230kV, sample and analyze dielectric fluids, perform field repairs, and run preventative maintenance programs across the contiguous United States.

Product overview

Power Substation Services is a service-based company offering a unified portfolio of transformer maintenance and servicing solutions. The core offering centers on eight interconnected service modules: Transformer Maintenance (comprehensive equipment care), Electrical Testing (diagnostic electrical assessments), Transformer Fluid Analysis and Sampling (19-point oil testing for condition monitoring), Transformer Oil Reclamation (hot oil purification on energized units up to 230kV), Transformer Vacuum Filling (new transformer assembly and filling), Field Repairs (on-site repairs including regasketing, welding, component replacement), and Transformer Retrofill (fluid replacement for mineral oil, ester, or PCB conversion). These services work together to provide complete transformer lifecycle management from installation through maintenance to fluid management, serving substation, power, and GSU transformers up to 1300 MVA and 765 kV ratings across the contiguous United States.

Products and services

• Transformer Oil Reclamation On-site hot oil reclamation service that purifies transformer dielectric fluid while the transformer remains energized up to 230kV, removing acid, water, and dissolved gases to extend transformer life.
• Transformer Vacuum Filling Vacuum filling service for transformer assembly using a 3000 cfm vacuum pump to remove moisture and air voids, with oil heated, dehydrated, and degassed before entering transformers up to 765 kV and 1300 MVA.
• Field Repairs On-site transformer maintenance and repair services including regasketing, welding repairs, bushing replacement, radiator replacement, load tap changer service, internal and external inspections, and transformer retrofit.
• Transformer Fluid Analysis Comprehensive fluid testing for predictive maintenance, including dissolved gas analysis (DGA), moisture content, acidity, dielectric breakdown voltage, and furan analysis.
• Transformer Fluid Sampling Comprehensive 19-point transformer oil sampling and testing covering acid content, IFT, dielectric 877 and 1816, color, moisture, sediment, power factor, PCB, specific gravity, viscosity, furan, DGA, ICP metals-in-oil, and particle count.
• Transformer Retrofill Drains and replaces dielectric fluid with same or alternative fluids such as mineral oil, natural ester, or synthetic fluids, including PCB fluid replacement, based on customer application and regulatory needs.
• Electrical Testing Power transformer electrical testing using state-of-the-art equipment with advanced software for data storage and report generation, including Transformer Turns Ratio (TTR), Insulation Resistance, Winding Resistance, Current Transformer Ratio, Power Factor Testing, Excitation Testing, and Sweep Frequency Response Analysis (SFRA).
• Transformer Maintenance Comprehensive transformer equipment maintenance programs including inspections, oil analysis, thermal imaging, insulation integrity testing, dielectric testing, and partial discharge analysis to ensure uninterrupted power delivery and extend transformer lifespan.
