Value Added
Columbia, S.A. 125MW Hydro generator stator incurred seven arc flash damages. VAI protocol was used to repair it in place and get the unit back online.

Claim Damage, Reparability, Replacement Valuations, Salvage
OEM “Cannot determine the Root Cause”
VAI identified the root cause converting insurance claim to OEM warranty
SF6 Breaker
AI created a 2-day by-pass for a damaged SF6 breaker Avoiding B.I.
550 MW STG Loss of DC Power
The insurers asked us to do an EPC Design Review, we listed several un-safe modes of failure. This design was used in 6 other power plants in South America.
6,500 HP Motor- Red Gear-Ball Mill
After years of Mill and Motor failures, VAI determined, in two days, that a soft-start liquid resistor had failed
OEM Blames Owner for Damaging H.P. Impulse Wheel
Manufacture compromised the blades, making them susceptible to steam admission excitation and subsequent failure.
6 MW STG Rotor Liberation
The insurers asked us to do an EPC Design Review, we listed several un-safe modes of failure. This design was used in 6 other power plants in South America.
Repetitive Compressor Failures
Repetitive Compressor Failures VAI identified a marginal design Recommends risk mitigation to insurance underwriters.
501J CTG 330 MW
We participated in the TP inspections, at night and on the weekend. Five TPs declared contaminated, although no contamination was visible – only water marks (dried deposits).
Wind Turbine Generator
Latent Design Defects
250 MVAR Synchronous Condenser
New units developed pole cracks Identified a manufacturing error
Solar Energy Thermal/Photovoltaic
Latent Design Defects, Mis-managed Upgrades, Operational Damages
Argentina, S.A. Transmission Distribution
New repairs to a 45-year paper insulated line induced secondary cracking and compromised the integrity of the paper insulation (causing cracking).
Compressor Clashing (“Surge”)
250 MVA Transformer
Superficial casing damage the owner rejected the unit, but easily repaired for spare unit
Operators were blamed for their loss. Clashing often is based on “surge conditions” Clashing is due to the physical flexing of the outer casing.
