Roodepoort School Service

A campus that could not afford a weak start to term

The school needed a careful maintenance visit before steady rain and thunderstorm activity started in Gauteng. In a campus setting there is no room for guesswork, because a generator that starts late can affect lights, access control, computers, alarm systems and exam spaces all in one go.

The brief was clear: carry out a service contract visit on the backup set, check the changeover arrangement, confirm the batteries were holding charge and inspect the fuel side for any signs of water contamination or leaks. The client also wanted a clean service record that could be used for internal planning and municipal or insurer queries if needed. Our team planned the visit around school hours and security access, which helped keep foot traffic away from the plant room.

Roodepoort can get heavy afternoon storms in summer and the school wanted the generator ready for that period. Load shedding is one pressure, but rain, damp air and mud carried into service areas create their own problems. We treated the site as an operating campus, not a workshop job, so every step had to be tidy and logged.

What we found in the first inspection round

The set was serviceable, but a few small issues showed up during the first inspection. Filters were nearing the point where restriction could become an issue, the coolant condition needed verification and the battery terminals needed cleaning before a high-demand week started. The changeover switch also needed a functional check to confirm the contacts were moving correctly and the transfer sequence was sound.

We also checked the fuel system for sediment, checked for soft leaks around visible fittings and reviewed the service history against the current condition of the set. On school sites, dust from sports fields and footpaths often settles into plant rooms, so even a normal service can reveal more than expected. One loose cable tie and a blocked drain point can turn into a nuisance if nobody notices it in time.

• Battery voltage and cranking response checked under load
• Oil level, oil condition and filter condition reviewed
• Coolant level, hose condition and visible clamp security checked
• Fuel side inspected for water, sludge and contamination signs
• Changeover switch function tested in a controlled sequence

The service visit at ground level

RelGen carried out the scheduled service over two site visits spread across one week, with the full contract intervention completed in week 2 after parts and test timing were confirmed. We drained and replaced service fluids where required, renewed the oil and filters, topped up the coolant to the correct level and cleaned the battery connections. The starter system was checked as part of the routine because repeated short outages can expose weak components very quickly.

The team then completed a load bank test to confirm the generator could carry a stable load for an extended period instead of only starting and idling. That matters on a school campus because a set can look fine during a brief test but still struggle when asked to carry real demand for longer periods. Electrical work was handled by qualified people in line with local regulations, and the changeover checks were done carefully so the school’s circuits stayed protected.

We also audited the service records on site and updated the findings in a way the school could file with its maintenance log. The process was practical and fairly quiet, with no disruption to classes and only a short planned interruption for testing. There was one small delay while security confirmed access to the service area, which is normal on campuses and did not affect the outcome.

• Oil and filter service completed
• Coolant system checked and topped up
• Batteries cleaned, tested and retained after passing inspection
• Load bank test completed to verify running performance
• Changeover switch checked for correct transfer behaviour

Why the rainy season changes the risk profile

In Roodepoort, the wet season brings more than just rain. Humidity climbs, condensation can form in plant rooms and water tracked in on shoes or trolleys can affect floors, cable entries and storage areas. A generator service contract has to take those local conditions into account, especially on a school campus where there are many moving parts and different users touching the same facilities.

We paid particular attention to keeping the area clean around the set and making sure the surrounding space would not collect standing water. Fuel and moisture do not mix well, and a small contamination issue can show up as rough running or failed starts at exactly the wrong time. This is where preventive site inspections earn their keep. They catch the slow changes before they become a callout at 6 a.m. on a Monday.

The client wanted a dependable backup power arrangement, not a flashy report. That fit the job well, because school maintenance is about staying ahead of the weather, the school calendar and the budget cycle. A set that starts first time and transfers cleanly is worth more than a lot of talk.

How the campus responded after the visit

Once the service was complete the school had a generator with improved starting confidence and a cleaner paper trail for future maintenance. The load bank result gave the management team a clearer picture of what the set could do under sustained demand, and the service record audit made it easier to plan the next maintenance window.

The biggest result was reduced uncertainty. There is always a difference between a machine that has been heard starting and one that has actually been maintained for the months ahead. The school team knew where the weak points had been, what had been corrected and which items should be watched before the next season shift.

For a campus this is the real gain: fewer surprises, better planning and less time lost during outages. The work did not need drama. It needed method, clean handover notes and a generator that could be trusted when the clouds rolled in.

What worked well

If we were doing the same type of job again on another school campus, we would keep the same sequence: inspect first, test second and close out the records only after the set has proven itself under load. That order helps avoid quick fixes that look fine on paper but fail in wet weather or after repeated start cycles.

We would also keep the visit around a quiet window in the school timetable, because reducing disruption is part of the job. On a live campus, good timing matters almost as much as good spanners. The other habit worth repeating is a plain service report with enough detail for the maintenance team to follow up later without chasing missing notes.

• Plan the service before the first serious storms
• Confirm battery health and transfer function early
• Keep the fuel side under close watch for moisture
• Test under load, not only at idle
• Leave the site clean and the records current
