Tier 1-4: Increasing secure 24/7 operation in data centres

Certified power quality monitoring and fire protection enhancement

Preamble

The volume of digital data continues to increase rapidly and steadily. Not least caused by cryptocurrencies, such as Bitcoin (XBT), Ether (ETH), Litecoin (LTC), etc. or, for example, by the blockchain process, a quasi-type database that works on various networked servers. The increasing demand for data exchange also increases the need for data centres, which are planned, built and maintained on a large scale globally. However, data centres in the electrical energy context are subject to complex challenges that can influence (legally) secure 24/ operation.

The basic requirements

When planning the energy supply of a data centre, many demands must be taken into account:

  • Secure location in terms of energy supply and environmental conditions
  • High energy efficiency to minimise operating costs
  • Maximum availability (Uptime Insitute Tier 1-4) through use of redundancies, e.g. UPS, generators
  • High security (fire protection, access, defence against cyber attacks)
  • System stability and reliability of the operating resources used
  • Scalability

The problem description

Various studies show that power quality problems cost billions each year. Read more

HuiShang Bank increases 24/7 operational security

Network quality monitoring in a bank data centre

Data centres are not only found in stand-alone form around the world, but are also found in many other sectors. These include banks, insurance companies, industrial enterprises, hospitals, airports, energy suppliers, public authorities, etc. It is not only the enormous energy demand that poses major challenges for data centre operators and energy suppliers. Additional factors that can lead to ad-hoc problems and serious damage are coming more and more into focus.

Investment in more security for 24/7 operation

As listed in this use case, HuiShang Bank Hefei / Anhui Province in China has chosen to invest further in Read more

Monitoring in 400Hz networks

Application example in the aviation industry

Basic

With the exception of a few special applications, power distribution systems worldwide operate at 50Hz or 60Hz. In the aviation and marine industries, where 400Hz networks are used to increase efficiency, this is different. This may be a challenge, as most of the measuring instruments available on the market are for applications in the 50 and 60 Hz range.

Misjudgement

It is often heard that the fundamental frequency is not important in the AC grid. Therefore, a measurement system used would be suitable for any frequency range. However, the non-compliant use of 50/60Hz Read more

System for power quality, energy management and pump automation

Actual situation

In a large urban city, the technology for supplying fresh water is getting old. Although the pumping stations and the infrastructure are in good condition, the maintenance and repair costs are continuously and extremely increasing. Electrical monitoring of the entire system is only available to a limited extent, and if so, only partially. Read more

Efficient use of an integrated web browser function

No external software is required for the parameterisation of the unit or the evaluation of the measurement results. The web interface provides all the necessary functions. These can be accessed via end devices such as smartphones, tablets, laptops, desktops and servers via the LAN or WLAN interface using an IP address.
