Intelligent Predictive Monitoring: The New Era of Generator Set Management

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

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

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

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

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

 The biggest challenge facing generator sets lies precisely in the nature of their operation: unlike other critical equipment, which operates continuously, generators remain inactive until they are needed. They're like emergency parachutes—they need to function perfectly the first and only time they're 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 fire broke out. In another, even more serious case, a hospital in Rio de Janeiro faced tragedy when a fire that started in a generator resulted in 14 deaths and 97 injuries. These are not isolated cases—they are dramatic reminders of the hidden risks in seemingly safe equipment.

In data centers, where every second of downtime can cost thousands of dollars, a generator failure means more than financial losses: it represents the interruption of essential services that affect thousands of users. In industry, an unscheduled shutdown can result in the loss of entire production batches, damage to sensitive equipment, and, in some cases, even pose a safety risk to workers.

The False Sense of Security of Traditional Maintenance

The traditional approach to generator set maintenance can be compared to taking a monthly snapshot of something that changes minute by minute. During periodic inspections, technicians check fuel levels, test batteries, and perform standardized procedures. The generator is turned on 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," says an engineer with two decades of experience in the industry. "I've seen cases where someone needed to jump-start a truck and temporarily removed the battery from the generator. When they replaced it, a poor connection compromised the system. In another situation, employees used the generator's fuel for other purposes, leaving the tank dangerously low."

 These inspections cover only 1% of the total operational time, leaving the actual condition of the equipment unknown for 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 unattended for 99% of the time.
• Over-reliance on human intervention : prone to errors and limited visibility into 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 checks 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 recording : 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 actual equipment usage.

The Smart Monitoring Revolution with Bridgemeter

To address these challenges, 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, overseeing every aspect of the equipment 24/7.

The system operates with multiple layers of protection. At its most basic, it continuously monitors critical parameters such as fuel levels, battery status, engine and oil temperatures, pressures, and electrical data. However, it's at the intelligence layer that Bridgemeter truly shines.

Imagine, for example, a sudden drop in fuel levels during the early morning hours, without the generator having been activated. Within seconds, the system identifies the abnormal 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, undetectable in conventional testing, are detected and reported before they cause failures.

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

Engine Monitoring :​

• Engine and oil temperature
• Oil pressure
• Engine RPM
• Hour 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 autonomy
• Average consumption

Environmental Monitoring :

• Room temperature
• Smoke detection
• Leak sensors
• Ventilation

Bridgemeter provides continuous and intelligent monitoring, allowing you to anticipate problems and significantly increase the security and reliability of your backup systems.

The Intelligence Behind Monitoring

Bridgemeter stands out for its predictive analytics capabilities, going beyond simple data collection by interpreting it within each client's specific operational context. 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 facility.

This intelligence isn't limited to a single device. In environments with multiple generators, Bridgemeter coordinates testing and operations seamlessly, 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 according to the actual condition of the equipment

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

This intelligence extends beyond individual equipment. In facilities with multiple generators, the system can coordinate testing and operations, ensuring that the load is distributed appropriately and that equipment is exercised evenly.

In short, Bridgemeter can:

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