  • Electrical damage restoration.

What is Preventive Electrical Maintenance?

Regular preventative maintenance is necessary to ensure that all electrical infrastructures are in perfect condition and doesn’t represent a risk.

To do so, periodic maintenance & service durations must be established before an issue arises. It’s an outline for trouble to wait until something critical breaks before fixing it.

In the optimal situation, the equipment would malfunction and produce unplanned downtime, which will reduce production and result in a financial loss.

In the worst condition, it can result in an electrical fire that threatens workers’ health and safety in risk.

Where is the Electrical Maintenance carried out?

1). In Residential Areas

Even while routine preventative maintenance of electrical systems is essential for enterprises and public structures, it shouldn’t be neglected for private residences.

With appropriate preventative maintenance, the probability of these types of incidents may be reduced.

2). In Commercial and Industrial Establishments

Due to the quantity of electrical equipment they use, factories and commercial buildings are equally as prone to have electrical fires.

Preventive maintenance on electric motors may assist keep equipment working and save downtime.

The first concern is to ensure their safety while working near and with electrical equipment.

3). Health care

The huge variety of essential equipment used by hospitals, private practises, and nursing homes should routinely get electrical preventative maintenance.

These accessories of medical equipment must function flawlessly at all times to ensure the staff’s and patients’ health and safety.

To continue treating patients in the event of power outages or crises, hospitals that have an emergency power source must ensure that it is maintained on a regular basis.

Checklist for Electrical Preventive Maintenance

1). Routine checks and repairs

Regular inspections should be performed on any electrical equipment used by a family or business, whether it is an affordable forklift (or) something as simple as a kettle.

This might occur at different intervals depending on the kind of device.

Pre-emptive inspections may find weaknesses before they develop into more serious problems, allowing for timely repair or replacement of the equipment or gadget.

This prevents electrical connections & local networks from becoming damaged or malfunctioning.

2). Systematic examination of electrical distribution

The complete electrical distribution network should be included in the electrical preventative maintenance, not simply the individual electrical equipment.

A professional electrical inspector may find faults and deficiencies that may result in electrical fires.

Power failures, fires, (or) even deaths may be avoided by repairing or replacing defective components.

3). Recollect service tools

When creating an electrical preventative maintenance plan, it’s important to remember any service devices that is crucial to the business.

Every essential component of equipment required for the smooth operation of the company must be identified.

4). Examine the lighting systems

The electrical preventative maintenance programme includes lighting systems, which are simple to neglect.

Most of them don’t consider how established electric light is in daily existence until it’s gone.

Even the lighting system must be regularly inspected to ensure that every component is in good condition and to prevent blackouts.

5). Examine on the electrical systems in dangerous areas

Working in hazardous environments may be risky, and it becomes considerably worse if an electrical problem results in a fire.

To minimise mishaps, malfunctions, and possible fires, it is essential to adhere to the electrical preventative maintenance programme.

6). Check out the Special Occupancy Units

Electrical problems may occur in areas other than residential or commercial buildings.

To maintain public safety, electrical systems in schools, jails, hospitals, childcare centres, and other public facilities must undergo routine maintenance.

7). Examining for Electrical Malfunction Warning Signs

Electrical issues must be avoided at all costs since they are one of the main causes of electrical fires.

A qualified electrician may identify flaws and monitor out for malfunctioning indicators by performing routine maintenance inspections before they become an issue.

Maintenance Flow Chart

How to make a Schedule for Electrical Preventive Maintenance

1). Sort equipment based on its need for maintenance

More often than others, certain machinery and systems need maintenance.

Using an electrical preventative maintenance programme, can establish up service intervals & reminders in accordance with manufacturer recommendations and regulatory regulations.

So, important service appointments are not going to be neglected.

2). Assemble equipment data

It is necessary to collect important details about equipment with the use of the electrical preventative maintenance software.

It is crucial to monitor management software if service intervals are dependent on runtime.

3). Identify Maintaining Needs

With the aid of the software, guidelines, and manufacturer recommendations, can gather the most crucial data, assess the individual preventive maintenance requirements of all the assets, machines, and electrical systems, and forecast when maintenance will be most beneficial.

4). Create a plan for routine electric maintenance

Routine Electrical Maintenance

With the use of all this information, an owner or facility manager may create an electrical preventative maintenance programme that is customised for the business and each asset.

Utilising a template for an electrical preventative maintenance programme that can be customised to a company’s specific requirements is another option.

5). Verify results and Modify as Necessary

After the maintenance plan has been implemented for some time, it is advised to evaluate its effectiveness.

To determine which areas still need correction and improvement, this may also be done using an electrical maintenance preventative programme.

6). Expansion of electrical prevention maintenance program

Expanding the plan to include previously excluded components is advised if new equipment is installed if downtime still occurs despite a suitable timetable.

The timetable should be updated as soon as new equipment is purchased, in particular.

Procedures for electrical maintenance


The majority of the electrical maintenance consists of monitoring the state of the equipment, doing condition-based maintenance, occasionally engaging in predictive maintenance.

Apply some of the following techniques, which are as follows:

1). Preventive maintenance 

2). Predictive maintenance

3). Failure finding maintenance

4). Reactive maintenance

1). Preventive maintenance 

Preventive maintenance refers to a wide range of tests, some of which include the relay,

  • The circuit breaker,
