Failure mode definitions

Modular UPS systems are usually presented as being extremely reliable with regards to their output. This is because the best modular UPS systems are designed to increase the reliability and availability of the overall system with minimum downtime thanks to their hot-swappable parts and cost-effective redundancy, the complete independence of each module and the prevention of fault propagation if one of the modules fails..

The impact of a power module’s MTBF value on the modular UPS system

The best modular UPS systems are designed to increase the global system’s reliability and availability with minimum downtime due to their hot-swappable parts and cost-effective redundancy, the complete independence of each module and no fault propagation if one of the modules fails.

Technical notes

 

IEC 61557-12 reference standard

To understand the operation of an electrical installation and to anticipate any risks of deviation, the parameters that govern the operation of the equipment must be monitored. To do this, appropriate measuring devices must be installed to gather the measurements.

Advanced measurements

A measuring unit performs a number of functions, from simple power consumption readings to advanced measurements related to the quality of the electrical energy. This document discusses these advanced measurements and their usefulness in practical applications.

Implementing ISO 50001

Published in 2011, ISO 50001 is the international standard for energy management. Its purpose is to allow companies* to put in place the necessary systems and procedures to improve their energy performance, including energy efficiency, energy use and consumption for all types of fluids (water, gas, electricity, etc.).

MID Directive

The MID (Measuring Instrument Directive) is a European directive dating back to March 31, 2004 (2004/22/EC). It applies to devices and systems with a measuring function, such as water, gas, electrical and heat meters and weighing instruments used in commercial transactions. The objective of the MID is to ensure a high level of reliability and metrological assurance so that any involved party can trust the measurement readings.

Overall accuracy

Measurement is crucial to reducing power consumption. But all too often, when faced with a choice of measurement solutions, the user focuses on the accuracy of the measuring device (PMD), forgetting to take into account the accuracy of its sensors. But the accuracy of measurement is inextricably linked to the accuracy of the overall chain, i.e. the PMD and its associated sensors.

Radio Frequency (RF) installation rules

RF communication is a good alternative if there is no wired network or if a measurement point is remote or isolated from the communication network. It is also very practical for adding measurement points into an existing installation without modifying the existing communication architecture.
