Product Usage Instructions:

Design Phase:

Our engineering teams focus on continuous improvement using
advanced tools like Finite element analysis (FEA) and 3D CAD
design. We collaborate closely with turbine manufacturers to ensure
optimal design for the turbine-generator system.

Production Phase:

Our generators feature a high-pressure jacking oil system, rotor
earth fault detection, vibration monitoring equipment, and other
advanced features. The IM 3011 mounting arrangement allows for
easier integration and maintenance operations.

On-site Handling:

We provide tools for safe transport and handling of the
alternator, including equipment for lifting and transferring
between horizontal and vertical positions. Solutions are available
for hard-to-reach sites and cramped machine rooms.

Comprehensive Options:

Our generators come with a range of options such as water
leakage detection, anchoring equipment, and optimized terminal
boxes for integrating transformers, surge arresters, and more.

Design
Our highly skilled engineering teams focus on optimization and continuous improvement resulting in the highest performances available on the market (efficiencies, life span and mechanical behaviour).
For this purpose, we use the best computation tools relying on Finite element analysis (FEA) and 3D CAD design.
Close coordination work with turbine manufacturers can be performed in order to refine deisgn and ensure a sound behaviour of the turbine-generator system on site.
Production
Our production site (Orléans, France), is equipped with state-ofthe-art machinery. We achieve product excellence and reach expected performances through controlled high quality components and processes at every step. CNC plasma and laser cutting tools, precision form-wound winding, vacuum-pressure impregnation are some of the equipment operated by qualified and dedicated workers.

Digital Static Excitation System
Transition your old generator static excitation to digital.
The Leroy-Somer Digital Static Excitation System can be installed on older generators. It combines the proven technologies of a Leroy-Somer designed digital AVR like the D550 or D700 and a Leroy-Somer Mentor DC drive.
The drive provides a continuous direct excitation current up to 900A, controlled by the digital AVR with the following features: – Automatic or manual voltage regulation – Voltage equalization for grid connection – Cos , Power Factor or kVAR regulation modes – Advanced fault detection and data logging – User-friendly touchscreen interface
