Removing contamination from generator and electric motor windings using Electrosolv-E

Instructions for removing contamination from generator and electric motor windings using Electrosolve-E.

1. De-energize the generator. Switch off the heater. Remove the filters.

2. Check the insulation resistance of the stator. Check the insulation resistance of the rotor, observing safety precautions.

3. Provide maximum convenient access to the stator and rotor windings.

4. Apply clean undiluted Electrosolve-E to all accessible surfaces with a brush or spray for pre-soaking. The product must be able to saturate all the dirt accumulated on the windings. It is advisable to turn the rotor for good access. Do not be afraid to apply the product to the terminals and bare wires.

5. Electrosolve-E will flow down into the bottom of the generator. A drain for the accumulated product must be provided.

6. Do not check the resistance of the windings while the generator is wet!

7. No earlier than 40 minutes later, start applying fresh Electrosolv-E with a brush or, better yet, a spray until the flowing product completely washes out the dirt dissolved by the first wash from all accessible places. That is, continue washing with the product until the product flowing out of the generator becomes crystal clear – like new.

8. Now you need to start drying the washed generator windings with compressed air. Only clean household air should be used (the ship's dehumidifier and oil separator should be in operation) with a pressure of up to 3-5 kg/cm2. Do not use starting air or a very strong air stream – to avoid mechanical damage to the varnish coating. Drying is the longest event in terms of time.

9. Continue drying with air until the surface becomes as degreased as possible.

10. If you plan to varnish the generator windings, you should perform a final degreasing of the generator surfaces with a 5% aqueous solution of Aquabreak PX or Uniwash. Use clean distilled fresh water and wash all surfaces of the generator (electric motor) with a sprayer (atomizer).

11. It is necessary to dry (dry) the windings with hot air (a fan heater), spotlights or built-in drying means. As it dries, the insulation resistance will increase. As soon as the changes stop, drying can be completed.

12. The dried surface can be varnished.

So, you need to check the presence on the vessel:

1. A sprayer (atomizer) with which you can wash away the contaminants dissolved by the first impregnation. If not, then you can use the Unitor Spraying Device.
2. A normal source of compressed clean air.
3. A fan heater, built-in heaters, portable spotlights, several liters of Aquabreak PX or Uniwash.

On average, 15-25 liters of Electrosolve-E is enough for one generator with a capacity of 400-500 kW.

Please note that there are no miracles in the world - Electrosolve-E removes dirt that can cause a decrease in insulation resistance, but Electrosolve-E cannot restore damaged varnish coating (if it is damaged).

Electrosolve-E is a powerful, chlorine-free solvent with a controlled evaporation rate, designed for cleaning and degreasing electrical equipment and components. It effectively removes oils and non-polar contaminants and, when used with a brush, helps remove oxides. Electrosolve-E is suitable for cleaning connectors, contacts, circuit breakers, microprocessors, as well as LED components and printed circuit boards.

Application Recommendations:

• Methods of Application: Electrosolve-E should be used undiluted. It can be applied with a brush, swab, or as a fine mist using appropriate manual spray equipment.
• Precautions: Do not use Electrosolve-E on an operating generator or motor. It may affect certain types of rubber and plastic; it is recommended to either remove such parts before cleaning or test the product on a small area to check for any reaction.
• Ventilation: Electrosolve-E should only be used in well-ventilated areas.
• Post-Cleaning Check: After cleaning motors or generators, it is recommended to check the insulation resistance to ensure it is within acceptable limits.

Brief instruction:

Electrosolve-E is a non-conductive, fast-evaporating electrical cleaner used for removing contamination such as dirt, grease, oil, and carbon deposits from generator and electric motor windings. Here’s a step-by-step guide for using it effectively:

Procedure for Cleaning Generator & Motor Windings with Electrosolve-E

1. Safety Precautions

• Power Down: Ensure the generator or motor is completely powered off and disconnected from any electrical supply.
• Ventilation: Use Electrosolve-E in a well-ventilated area to avoid inhaling fumes.
• Personal Protective Equipment (PPE): Wear gloves, safety goggles, and a mask to protect against solvent exposure.
• Fire Safety: Since Electrosolve-E is flammable, keep it away from open flames, sparks, and hot surfaces.

2. Cleaning Process

1. Preliminary Cleaning

   • Use compressed air or a soft brush to remove loose dust and debris from the windings.
   • Inspect for heavy grease or carbon deposits.

2. Application of Electrosolve-E

   • Spray Electrosolve-E directly onto the windings and contaminated areas.
   • Let the solvent penetrate and dissolve the contaminants.
   • For stubborn deposits, use a lint-free cloth or soft brush to agitate the dirt.

3. Drying Process

   • Allow Electrosolve-E to evaporate completely. The fast-drying nature of the solvent ensures no residue is left.
   • Use compressed air to accelerate the drying process and remove any dissolved particles.

4. Final Inspection

   • Check the windings for any remaining dirt or contamination.
   • If necessary, repeat the cleaning process for optimal results.

3. Post-Cleaning Steps

• Ensure the windings are completely dry before re-energizing the equipment.
• Perform a megger test (insulation resistance test) to confirm there is no moisture or conductive residue left.
• Reassemble and reconnect the generator or motor.
