Alimentation de secours des sites critiquesUne alimentation de secours qui démarre quand il le faut.
Quand le réseau tombe, hôpitaux, usines d’eau, centres de crise et nœuds de télécommunications fonctionnent sur groupes électrogènes et batteries. Beaucoup ne démarrent pas, manquent de carburant ou disjonctent en charge. Surveiller chaque groupe, cuve, batterie et inverseur de source, avec des essais consignés, fait de l’alimentation de secours un fait plutôt qu’un espoir.

Résilience civile · Alimentation de secours des sites critiques
The outage is the test
Quand le réseau tombe, hôpitaux, usines d’eau, centres de crise et nœuds de télécommunications fonctionnent sur groupes électrogènes et batteries. Too often a generator does not start after months idle, a tank is low, or a battery no longer holds. Standards ask for regular tests; between them, backup power is usually watched by no one.
Ce qui est mesuré
Engine, fuel, battery and switch
Meters read generator output and load, sensors read fuel level and quality in day and bulk tanks, battery systems report state and runtime, contacts read the transfer switch position, and engine sensors read vibration and temperature during every run and test.

Le nœud de base
Runtime, computed
The node computes how long each site can run from fuel, load and battery state, detects failed starts and failed transfers, flags fuel quality problems and engine faults, and records every test and outage automatically, so the evidence inspectors ask for is complete.
Radio et liaisons
Reporting through the blackout
Cellular carries power state from each site and survives grid outages where cell sites have their own backup. Sites that must report through long regional blackouts add a satellite path. The monitor runs on the site’s protected supply, so it reports the outage it is there to watch.

Comment ça marche
From a blackout to a fuel truck
A storm blacks out a region. Generators start at forty sites; one fails, and its crew is sent at once. The emergency centre sees runtime at every site, and fuel trucks go first to the water plant and the hospital with the shortest time left.
De la commande à l’exploitation · Commande
Scope the critical load
The scope reads each site’s critical loads, its generators, tanks, batteries and switches, test records, outage history and the fuel contracts. Nexus Observatory Inc. returns the monitoring kit per site, the runtime and fuel model, test reporting and a price per site and per year.

Survey every power room
Crews survey generator rooms, tank farms, battery rooms and switchboards with the site engineers: controller interfaces, tank access for sensors, meter points, switch contacts and backhaul coverage. Each finding is recorded with photographs and single-line drawings. Findings shape the kit for each site before anything is built.
De la commande à l’exploitation · Autorisations
Electrical safety and permits
Work on switchboards and generator controllers follows the site’s electrical safety rules and permits to work, often in planned windows for hospitals and plants. Fuel system work follows the fire safety rules for flammable liquids. Every permit is kept with the site record.
De la commande à l’exploitation · Fabrication
Build to the site’s single line
Kits are built to each site’s single-line diagram: meters, fuel sensors, contacts and engine sensors mapped to the gateway, nodes enrolled with their identities and configured with tank sizes and loads. Everything is tested together before shipping. Nothing ships until the whole kit has passed its tests together.
Ouvrir le configurateur de stationsDe la commande à l’exploitation · Installation
Install in planned windows
Crews fit meters, fuel sensors, transfer switch contacts and engine sensors during planned windows, with critical loads protected throughout. Gateways and nodes are mounted in the power room, backhaul is connected and every point is photographed. Crews follow the site safety plan throughout the work.
De la commande à l’exploitation · Mise en service
Commission with a load test
Chaque nœud prouve son identité. A planned load test starts each generator, transfers the load, runs it and transfers back, while every reading is checked against the controller and runtime is compared with fuel actually used. Results go into the test record.
De la commande à l’exploitation · Exploitation
Know the runtime
Operators see every site’s generators, fuel, batteries and runtime. In an outage, fuel deliveries go first to the sites with the shortest runtime, failed starts send crews at once, and every test and outage is recorded for inspectors and regulators.
De la commande à l’exploitation · Maintenance
Test on schedule, keep the record
Scheduled generator tests and battery checks are recorded automatically, fuel is sampled and polished when quality drops, engine trends schedule servicing, and node software updates roll out in rings. Every test and repair is kept with the site. Maintenance history stays with each site for its whole life.

For managers, crews and suppliers
Emergency managers and site operators receive runtime at every site; maintenance crews receive failed start and transfer alarms; fuel suppliers receive fuel needs by site; inspectors, auditors and regulators receive test and outage records, each tied to the site, the generator and the time.

Tests and outages on record
Monitoring and test records follow the emergency and standby power standard, generators are assessed against the generating set series, and records support the resilience duties of critical entities. Every start, transfer, test and outage is signed and kept, ready for inspection.

01Le lieu et ses dangers
Où il fonctionne, et ce qui peut mal tourner.
Operating contextEmergency and standby power systems are designed, tested and maintained to their own standards, generating sets are rated to the international generator series, and operators of critical entities must show their services survive disruption. Yet backup power is often tested rarely and watched by no one between tests.
Dangers
- Generators that fail to start after months idle
- Fuel that runs out, degrades or is stolen
- Batteries that no longer hold their rated time
- Transfer switches that fail to transfer
- Long outages that outlast the fuel on site

Satellite
Sites that must report through long regional outages add a satellite path.
Edge computeThe node computes runtime from fuel, load and battery state, detects failed starts and transfers, flags fuel quality problems and engine faults during runs, and records every test and outage.
PowerThe monitoring runs on the site’s protected supply with its own battery, so it reports the outage that it is there to watch.
