ELECTRICAL COMPONENT CLEANING
Maintenance is key component in efficient operation of electrical systems.
Electrical equipment failures account for millions of dollars in damage and lost business every year.
As electrical infrastructure continues to age, this problem is only going to get worse unless active steps are taken to counter the trend.
Ironically, more than two-thirds of electrical system failures can be prevented by routine preventative maintenance programs. the failure rate of electrical equipment is three times higher for components that are not part of a scheduled preventative maintenance program as compared with those that are.
In addition, a planned ERP (Equipment Reliability Program) allows the equipment owner to schedule the system outage at a time of their choosing rather than having to correct major problems resulting from an always untimely failure.
Electrical Equipment Failures – ARC FLASH CAUSES
An Electric Arc is a short circuit through the air.
- Dust & Impurities – Dust and impurities on insulating surfaces can provide a path for current, allowing it to flashover and create an arc discharge across the surface.
- Corrosion – Corrosion of equipment creates impurities on insulating surfaces.
- Condensation – Water vapor can drip causing tracking on the surface of insulating materials. This can create a flashover to ground.
- Spark Discharge – Accidental contact, Dropping tools
- Failure of Insulating Materials – Exposed surfaces that can provide a path for current.
- Improper Work Procedures – Untrained/Uncertified technicians and improper PPE usage.
Electrical Equipment – ArcFlash – Solution – Dry Ice Blasting
Dry Ice Blasting is the best cleaning method.
- Increases up-time through in-place cleaning – The process is fast, thorough and can be performed on-line without disassembly and without the need for drying time.
- Cleans without damaging the substrate – Dry Ice Blasting is non-abrasive. It quickly removes most contaminates without damage to switches, panels, lines, tubes, wiring or belts.
- Reduces or eliminates the need for hazardous solvents – Dry Ice Blasting replaces chemical or solvent based cleaning and manual scraping.
- Quicker and more thorough clean than cleaning by hand – get a more detailed and quicker clean with CO2 by getting into tight spaces that are inaccessible by hand.
- Safe around electrical components – This versatile process cleans heavy industrial build up without damage to sensitive areas like electrical components, switches, wiring, photo electric sensors, etc.
