Electrical Safety Monitoring and Hazard Early Warning for a Large General Hospital
Deploying ESA electrical safety monitoring alarm devices, ESB electrical safety monitoring terminals, EST temperature sensors and ESX products to perform 7x24h online electrical safety monitoring of key scenarios including hospital power distribution systems, operating rooms, ICU and ward buildings, with Real-Time perception of leakage current, temperature and current anomalies, safeguarding electrical safety and continuous Power Supply in medical locations, and protecting patient life safety and stable operation of medical equipment.
01 · BACKGROUND
Customer Background
Enterprise Type
A large general hospital integrating clinical care, teaching and scientific research, affiliated with the national health system and undertaking regional emergency and critical care as well as public health emergency response. The hospital has a large medical equipment asset base and high power load density, imposing extremely stringent requirements on power continuity and electrical safety.
Hospital type: large general hospital · scale per site survey
Key Scenarios
The hospital encompasses operating rooms, ICU, CCU, neonatal wards, hemodialysis rooms, imaging centers (CT/MRI/DSA), clinical laboratories, and central sterile supply departments. Medical equipment is diverse and power load fluctuates significantly; power interruption in operating rooms and ICU can directly threaten patient lives.
Key areas: OR, ICU, CCU, etc. · points per site survey
Industry Position
As a national critical medical infrastructure, the hospital must strictly comply with mandatory standards including JGJ 312 Code for Electrical Design of Medical Buildings, GB 51348 Standard for Electrical Design of Civil Buildings, and GB 50016 Code for Fire Protection Design of Buildings. Group 2 medical locations are required to meet IT system insulation monitoring and uninterrupted Power Supply requirements.
Compliance Standards: JGJ 312 / GB 51348 / GB 50016
02 · CHALLENGES
Business Challenges
High Electrical Fire Risk in Medical Locations
Hospital power distribution systems carry high load density with diverse medical equipment. Cable joints, socket circuits and distribution boxes are prone to heating caused by poor contact or overload, leading to electrical fire hazards. Hospitals are densely occupied with limited-mobility patients; once a fire breaks out, the consequences are severe. Traditional manual inspection can hardly detect hazards in advance.
Power Interruption Risk in Operating Rooms and ICU
Group 2 medical locations such as operating rooms and ICU demand extremely high power continuity. Any power interruption caused by electrical faults may directly threaten patient lives. Existing distribution systems lack Real-Time monitoring of terminal electrical status and provide no early warning before faults occur, allowing only post-event response and compromising emergency response efficiency.
Leakage Current Risk of Medical Equipment
Medical equipment (such as patient monitors, ventilators, anesthesia machines, electrosurgical units, etc.) is sensitive to enclosure leakage current. Insulation aging or poor grounding may cause leakage current to exceed limits, posing electric shock risks to patients and medical staff. Without online leakage current monitoring, early warning is impossible.
Compliance Audit Evidence Collection Difficulties
Electrical safety compliance audits of medical buildings require complete, continuous and traceable monitoring data. Paper records and discrete inspection data cannot meet the compliance audit and joint inspection requirements of standards such as JGJ 312 and GB 51348 by health commissions and fire departments.

Network Topology
Sensing Layer: ESA electrical safety monitoring alarm devices are deployed in hospital main distribution cabinets and floor distribution boxes; ESB electrical safety monitoring terminals are deployed in secondary distribution boxes of Group 2 medical locations such as operating rooms and ICU; EST temperature sensors are attached to key heating points such as cable joints, busbars, circuit breaker contacts and medical equipment sockets; ESX electrical safety monitoring devices are deployed in medical equipment control boxes and isolation transformer circuits, achieving full-scenario electrical safety monitoring in medical locations.
Network Layer: Each sensing terminal connects to the nearest ESX intelligent edge computing gateway via RS485 bus (Modbus-RTU protocol). ESX gateways uplink to the hospital logistics O&M network via hospital internal LAN / 4G cellular network, with key nodes supporting dual-link redundant backup to ensure data transmission reliability.
Platform Layer: Data aggregates to the FEXLINK Cloud platform (privately deployed in the hospital logistics data center), providing web and mobile visualization dashboards, Real-Time alarms, historical trend analysis, O&M work order dispatch, compliance report auto-generation, multi-role permission management (logistics O&M / medical equipment department / fire safety management) and more.
Integration Layer: The cloud platform connects with existing hospital BAS (Building Automation System), FAS (Fire Alarm System) and logistics O&M management systems via standard REST API / Modbus TCP protocols, enabling data sharing and linked alarms, and incorporating them into the unified hospital logistics O&M work order workflow.
