Immediately after commissioning an inverter-driven CHP unit, several bus systems failed in the customer’s system. M-Bus, Profibus and Modbus modules were affected.
As a result of the bus malfunctions, there were constant error messages and false alarms in the process control and thus also failures of the entire plant.
Analyses of the system suppliers of the control equipment as well as complaints to the supplier of the CHP with subsequent inspection by the manufacturer did not lead to any results.

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
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
