Electrical Safety for Data Center Power Supply

Safety, maximum availability, and economic viability in server parks, data centers, and IT rooms are more critical than ever and require a fault-free power supply. The supplied medium voltage is transformed to 400 V in the transformer stations and fed to the data center via cable bars or busbars, the low-voltage main distribution board, and the standard sub-distribution panel. The regular system's sub-distribution panel also provides electricity to the uninterruptible power supply (UPS).

Bender AC/DC sensitive and multi-channel ground-fault monitoring systems permanently monitor the power supply. This avoids fire hazards, operational interruptions, functional problems, damage, and, in the worst-case scenario, data loss due to faulty electrical insulation or EMC influence. Bender’s ground fault protection and insulation monitoring devices help prevent power supply disruptions in data centers, reducing the risk of fire hazards and operational downtime. Bender monitoring systems add a critical layer of electrical safety and protect your data daily. Possible risks are recognized early before problems arise. Power quality is the perfect solution for monitoring low-voltage main distribution boards. Monitoring the central grounding points via an RCMS guarantees only one connection between N and PE in line with the standards. A safe power supply forms the basis for secure data — Bender technology ensures this happens.

Bender offers sub-distribution panel and busbar systems for an interference-free and straightforward connection. The connection between the low-voltage main distribution board and the sub-distribution panels is via busbar systems to guarantee the supply is as fault-free as possible. Power quality and RCMS residual current monitoring systems (ground-fault monitors) help with this monitoring. These solutions help ensure that the data center power supply is safe. By using line isolation monitors and ground fault protection, data centers can continuously detect and isolate electrical faults, preventing costly system interruptions.

Emergency power systems such as generators ensure an uninterrupted power supply. Electricity providers cannot always guarantee a perfect supply of electrical energies everywhere. Emergency power systems must bridge short interruptions or sustained power outages to maintain the operation of a data center, including the associated technical systems, such as air-conditioning, electricity, and security. The Bender solutions control the changeover and monitor the emergency power system for electrical faults.

It is critical to switch to emergency power without interruption for any length of time. An uninterruptible power supply (UPS) is used to ensure the supply of critical electrical loads in the event of problems in the power supply. The UPS systems (typically battery or oscillating weight systems) bridge the period until the emergency power systems (generators) are activated, or the system is available again. Bender products continuously monitor electrical safety, thus ensuring that the power supply in data centers is safe. Bender’s insulation monitoring devices, paired with line isolation monitors, provide real-time safety monitoring for generators and UPS systems, ensuring a seamless power supply in data centers.
