AC Generator Consultants provides test analysis, performs the vacuum
decay and pressure decay tests which can differentiate between
outgassing, virtual leaks and crevice corrosion leaks. Additional
stator tests to evaluate water contamination include capacitance
mapping of ground wall insulation, wet insulation detection (WID),
DC leakage step current rate changes, megger readings and specific
visual/tactile leak associated clues.
When you need experienced help in developing a repair proposal,
generator schedule, a second opinion for expensive repairs or a risk
assessment of your generators, please call AC Generator Consultant.
AC Generator Consultants has extensive experience in the
complicated, interrelated battery of tests which diagnose, evaluate,
and benchmark generator stator ground wall insulation and evaluate
for bar water leaks. AC Generator Consultants has been instrumental
in the development and analysis of Hydraulic Integrity Test (HIT)
skid tests, capacitance mapping, stator leak monitoring system and
bar clip leak repair.
The HIT skid test equipment first eliminates water droplets from
inside the stator water system by forcing air flow through the
liquid cooled winding hoses, strands, and headers. Air flow
direction and velocity is varied according to the generator
configuration.
The HIT skid then vacuum dries the stator water system by
evaporation with reduced system pressure. The evaporated water
eliminates water puddles, accumulations and causes water trapped in
internal oxide deposits to outgas. Clean and dry liquid cooled
stator windings can be tested at high voltage without significant
internal leakage current through stagnant water accumulations.
