ELECTRICAL MAINTENANCE PROGRAM
Why conduct regular electrical maintenance?
According to the National Fire Protection Agency (NFPA) of the United States, “nearly two-thirds of all electrical distribution fire losses could have been prevented.”
Recommended Practice for Electrical Equipment Maintenance NFPA 70B states that “a well-administered electrical preventative maintenance program will reduce accidents, save lives, minimize costly breakdowns and unplanned shutdowns of equipment.”
The Institute of Electrical and Electronic Engineers (IEEE) reports that “without preventative maintenance, the failure rate of electrical system components is three times higher.”
Occupational Safety and Health Administration (OSHA) and Standard for Electrical Safety in the Workplace NFPA 70E of the United States are mandating facilities perform electrical preventive maintenance on their equipment. Stay in compliance with our preventive maintenance programs.
In Viet Nam, Circular No. 32/2010/TT-BCT (Regulations On Power Distribution System) defines responsibilities of electricity buyer (customer) in planning routine maintenance and testing for electrical equipment in the distribution system. The electricity seller (power company) has right to stop supplying power if the customer does not comply with the requirements.
Let us help you comply with the electrical system maintenance regulations.
What is electrical maintenance program?
A preventive/predictive maintenance program is a schedule of regularly planned maintenance testing and actions with the intent of preventing breakdowns and failures. Finding and replacing worn components before they can actually fail is the goal of preventive service, as well as predicting useful life of existing equipment.
Electrical Preventive/Predictive Maintenance Services from Nhat Ha Electric will evaluate the condition of your equipment and determine the most cost-effective and manageable solution to ensure its overall performance, safety and reliability.
Elements of a good preventive/predictive maintenance program should include the following:
- Identification of equipment or systems that may malfunction
- Typical equipment to be inspected including switchgear, circuit breakers, transformers, switches, etc.
- Establishment of schedules and procedures for routine inspections
- Periodic testing of plant equipment for structural soundness
- Prompt repair or replacement of defective equipment found during inspection and testing
- Inventory of spare parts for equipment that needs frequent repairs
- Use of an organized record-keeping system to schedule tests and document inspections
- Commitment to ensure that records are complete and detailed, and that they record test results and follow-up actions
- Preventive maintenance inspection records should be kept with other visual inspection records
Let us help you design and implement a preventive maintenance strategy that will reduce your overall maintenance costs and the amount of time spent on unplanned maintenance. And more significantly, improve the overall reliability throughout your facility.
Benefits
- Reduce unplanned downtime

How can we do the maintenance service for you?
Nhat Ha Electric partners with your business to form maintenance agreements. An agreement can include the services of diagnostic testing, scheduled equipment maintenance, cleaning, lubrication, and many other services.
Around the clock, we can respond fast to your urgency and crisis mode with experienced engineering team and full of testing and diagnostic equipment. Our service will help to reduce your cost and minimize downtime.
with hi-end technologies in Thermographic (IR) Scan and Online Partial Discharge (OLPD) Test [Ultrasound, TEV, HFCT], our certified engineers are able to detect potential issues in the early phase from overload, unbalance or mechanical looseness causing high temperature hot-spot to degradation of insulation system leading to electrical discharge. These services will be performed online; thus, no shutdown (loss time) is required. The Condition Base Monitoring (CBM) will allow us to proactively repair and prevent unexpected incidents.
It is very important to schedule downtime and perform essential tasks of inspecting, cleaning, lubricating and torque tightening on all electrical equipment and components. We have the resources to perform the work swiftly and correctly. Besides, we offer a full list of testing services to ensure your electrical equipment to be functional. These include:
- Transformer testing (insulation resistance, power factor, turns ratio, winding resistance, no-load)
- Insulating oil analysis (breakdown voltage, water content, chemical characteristic, DGA, Furan)
- Insulating oil filtering and treatment (dehumidified purification)
- Medium voltage & low voltage cable testing (insulation resistance, VLF AC or DC high potential)
- Medium voltage & low voltage breaker testing (insulation resistance, contact resistance, protection, time travel)
- Instrument transformer (insulation resistance, winding resistance, turns ratio, polarity, excitation current, burden)
- Protective relay testing & calibration (electro-mechanical, solid state, microprocessor)
- Meter testing & calibration
- Power factor controller testing & calibration
- Switchgear and buss duct testing (insulation resistance, AC high potential)
- Station battery system testing (load bank, battery impedance – terminal voltage)
- Earth/ground testing
- SF6 gas leak detection and analysis (impurity and moisture content)
