The use of suitable current transformer sensors pays off

Accuracy of the measurement questioned.

Measuring instruments are usually classified according to standards and accuracy. Accuracy is an important indicator for being able to usefully build on a solid measurement result in the analysis and its resulting measures. However, it can be observed that although the measuring devices used correspond to a required accuracy class, the necessary sensors are often less in focus.

It can be seen that although class A measuring devices used in power quality applications correspond to a data sheet accuracy of 0.1% for U/I and 0.2S at the energy meter, upstream current transformers are often designed significantly worse (e.g. 0.5% or worse). And this is apart from the fact that not only accuracy plays a role in power quality measurements, but also the inevitable compatibility against harmonics – one of the modern and growing main players in power quality.

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

PQ Easy Report – Conformity reports at the touch of a button

 

With the “PQ-Easy Report”, statistical reports can be generated directly from the measuring instrument, either according to standard or also user-specific. And this completely autonomously and detached from proprietary software solutions that make life difficult for many users as well as the IT department.
