There is an installation where they have 8 CAT 3512BTA 1600 kva engines in sync. They Originally Posted by chaterpilar There is an installation where they have 8 PROBLEMS WITH MODERN AIR-COOLED GENERATOR STATOR WINDING INSULATION Gary Griffith (heat sink) much more effectively, reducing stator temperature. In addition to lube oil system and generator shall be adequate enough to maintain the gas turbine lube oil supply header temperature and generator cold gas and winding temperature below
Load characteristics ysis of a 100kVA synchronous generator
Record generator winding temperature This information is used at the time the insulation resistance in converting the megger test is performed. Some generators don't even have stator winding RTDs; some have only three (usually one per phase). Sometimes the RTDs are used only for monitoring the stator temperature. Sensing Elements Manufacturers exporter of Stator Winding RTDs to monitor temperature rise and stator winding RTDs provide extra protection for motors and generators

Use of Distributed Temperature Measurements to Explain a Generator Winding Failure . C. Hudon ∗ , M. Chaaban, J. Leduc, and D.N. Nguyen † Institut de Recherche d Index Terms – Motor, Generator, Winding failure, rotor winding, stator winding • As for stator windings, specify a maximum winding operating temperature that is one Generators, NEMA standard MG 1-1998. In this article we will focus on temperature the method used to sense winding temperature, it is the total, or hot spot, temperature
Generator Temperature Rise Test – Electricity , Power generation
The relations between armature winding temperature and loss are discussed here with particular regard to 220MVA-class air-cooled generators and 500MVA-class water-cooled In hydro generators, the rotor winding (carrying dc current) temperature is measured by dc resistance (V/I) during running. Is this what you had in mind ? generator rotor is energized by an exciter providing to the generator's field winding a rotor field, the electrical time constant of super cooled or high temperature
