Intelligent Predictive Monitoring: The New Era of Generator Set Management

It was a typical night shift at a large hospital when the unexpected happened: a total blackout in the region. In a matter of seconds, all the lights went out. This was exactly the moment the generator had been installed for. However, when it was most needed, the equipment remained silent.

 In the ICU, doctors and nurses scrambled to keep vital equipment running on emergency batteries, while technicians discovered, too late, that the fuel tank was practically empty – a situation that could have been avoided with a proper monitoring system.

 This story, unfortunately, illustrates the risks of operating without an intelligent and predictive monitoring solution. With Bridgemeter, the hospital could have identified and corrected the supply problem in advance, ensuring the continuity of essential care and protecting lives.

This scenario, unfortunately, is not fictional. It repeats itself with alarming frequency in facilities that rely on generator sets as a backup system. Studies in the US indicate a failure rate of 3% to 4% in these systems – a seemingly small percentage, but with potentially catastrophic consequences.

 In critical environments, such as hospitals, factories, data centers, and large commercial buildings, the continuity of power supply is not just a convenience, but a vital necessity. A single minute of interruption can generate significant financial losses, compromise essential operations, and, in the worst-case scenario, put lives at risk.

 The great challenge for generator sets lies precisely in the nature of their operation: unlike other critical equipment, which operates continuously, generators remain inactive until the moment they are indispensable. They are like emergency parachutes – they need to function perfectly the first and only time they are activated.

The Invisible Risks

In January 2024, a hospital in São Paulo experienced moments of panic when it had to evacuate its ICU after a small fire broke out. In another, even more serious case, a hospital in Rio de Janeiro faced a tragedy when a fire that started in a generator resulted in 14 deaths and 97 injuries. These are not isolated cases—they are dramatic warnings about the hidden risks in seemingly safe equipment.

In data centers, where every second of downtime can cost thousands of reais, a generator failure means more than just financial losses: it represents the interruption of essential services affecting thousands of users. In industry, an unscheduled shutdown can lead to the loss of entire production batches, damage to sensitive equipment, and, in some cases, even risks to worker safety.

The False Sense of Security of Traditional Maintenance

The traditional approach to generator maintenance can be compared to taking a monthly snapshot of something that changes every minute. During periodic inspections, technicians check fuel levels, test batteries, and perform standardized procedures. The generator is started for a few minutes, data is collected, and everything appears to be working perfectly. However, the next day, everything may be different.

 “It’s surprising how seemingly simple situations can compromise an entire backup system,” comments an engineer with two decades of experience in the sector. “I’ve witnessed cases where someone needed to start a truck and temporarily removed the generator battery. When they put it back, a faulty connection compromised the system. In another situation, employees used the generator fuel for other purposes, leaving the tank dangerously low.”

 These inspections cover only 1% of the total operating time, leaving the true state of the equipment unknown during the other 99% of the time. It's like driving a car whose instrument panel only works for 15 minutes a day.

 In summary, the limitations of traditional maintenance include:

• Insufficient time coverage : periodic inspections cover less than 1% of operational time, leaving equipment unsupervised for 99% of the time.
• Excessive reliance on human intervention : prone to errors and a limited view within the inspection range.
• Lack of continuous detection : problems that arise between inspections may go unnoticed until the critical moment.
• High costs : frequent trips for routine check-ups represent significant expenses.
• Lack of predictability : inability to anticipate failures before they occur.
• Lack of real-time monitoring : critical parameters are only checked during inspections.
• Difficulty in historical record keeping : lack of continuous data for trend analysis.
• Reactive response : problems are only identified after they occur.
• Inefficient maintenance : fixed maintenance intervals do not always correspond to the actual use of the equipment.

The Intelligent Monitoring Revolution with Bridgemeter

It was to meet these challenges that Above-Net developed Bridgemeter , a solution that transforms the way we monitor and manage any equipment, especially generator sets. More than a monitoring system, Bridgemeter acts as a tireless guardian, supervising every aspect of the equipment 24 hours a day, 7 days a week.

The system operates on multiple layers of protection. At the most basic level, it continuously monitors critical parameters such as fuel levels, battery status, engine and oil temperature, pressures, and electrical data. However, it is at the intelligence layer that Bridgemeter truly excels.

Imagine, for example, a sudden drop in fuel level during the early morning hours, without the generator having been activated. Within seconds, the system identifies the anomalous behavior and notifies the responsible team via the Bridgemeter mobile app, issuing alerts of a possible fuel leak or theft, preventing a potential future crisis. Similarly, subtle patterns of battery degradation, imperceptible in conventional tests, are detected and reported before they cause failures.

Bridgemeter enables real-time monitoring of the following critical parameters:

Engine Monitoring :​

• Engine and oil temperature
• Oil pressure
• engine RPM
• meter
• Cooling system
• Oil quality

Electrical Monitoring :

• Voltage
• Current
• Frequency
• Active and reactive power
• Power factor

Resource Monitoring :​

• Fuel level and consumption
• Battery status and charge
• Load and usage demand
• Estimated range
• Average consumption

Environmental Monitoring :

• Room temperature
• Smoke detection
• Leak sensors
• Ventilation

Bridgemeter offers continuous and intelligent monitoring, allowing for the anticipation of problems and significantly increasing the security and reliability of backup systems.

The Intelligence Behind Monitoring

Bridgemeter stands out for its predictive analytics capabilities, going beyond simply collecting data by interpreting it within the specific operational context of each client. When a generator is running, for example, the system simultaneously monitors and analyzes dozens of parameters, adapting to the type of operation and the individual needs of the installation.

This intelligence is not limited to a single piece of equipment. In environments with multiple generators, Bridgemeter coordinates tests and operations in an integrated manner, ensuring balanced load distribution and proper operation of each unit.

 In summary, Bridgemeter offers:

• Detection of anomalous variations that indicate potential problems
• Identifying degradation trends before they result in failures
• Autonomy calculation based on actual consumption
• Automatic alerts for critical conditions
• Scheduled maintenance based on the actual condition of the equipment

Bridgemeter is a solution that adapts to the requirements of each operation, maximizing the safety and reliability of the backup system and increasing the efficiency of preventive maintenance.

This intelligence extends beyond the individual equipment. In installations with multiple generators, the system can coordinate tests and operations, ensuring that the load is properly distributed and that the equipment is exercised in a balanced way.

In summary, Bridgemeter can:

• Detecting abnormal variations that indicate potential problems
• Identifying degradation trends before they cause failures
• Calculate range based on actual consumption
• Generate automatic alerts for critical conditions
• Schedule maintenance based on actual conditions
