Energy measurement
The acquisition and recording of energy variables and values as well as their evaluation and their further
processing are becoming increasingly important. This is not just due to rising energy costs but also due to
the frequent demands for the ability to evaluate and read via a decentralized reading station. Combined
with the features of the EQmatic series, convenient, cost-effective solutions for modern energy
management can be realized within the building control system for the operators or users. The demands
placed on recording and evaluation as well as on billing and charging in commercial and functional
buildings, and also in industrial systems and residential properties have increased significantly over recent
years. ABB offers a wide range of devices and solutions specially designed for these applications.
What is Automatic Meter Reading (AMR)?
Automatic Meter Reading (AMR) is the process of remotely reading data from meters. AMR allows the
suppliers of electrical energy, as well as water, gas and district heating to improve the handling of their
contracts and services. The ongoing costs involved in the manual reading of the meter are eliminated and
the consumption data become transparent.
What is energy management?
Energy management is the overall concept which ranges from the planning of the requirement to the
selection, installation and operation of energy generation systems. The objective is to provide complete
coverage of the energy needs of the consumer and to use the minimum amount of energy at the given
comfort or production levels (industrial and commercial). Energy management can be applied in every
building where energy is required: industrial buildings, office buildings, sports halls, dwellings, apartments,
etc.
Reasons for energy management:
•
Assurance of the provision of an interruption-free supply of energy or power
•
Retention of the voltage and current quality
•
Cost-effectiveness, e.g. low prices for power and heat, energy saving
•
Environmental aspects, e.g. energy saving, energy recovery
•
Independence of fossil-based primary energy carriers
•
Implementation of energy management guidelines and standards such as ISO 50001
What is load management?
The primary objective of load management is an economical and resource efficient use of energy provided
by electrical utility companies in industry, commercial applications and domestic households for
environmental cost and/or safety reasons. Load management also incorporates measures for the
avoidance of circuit overloads. Cost savings can be achieved by the avoidance of load peaks or reduction
of consumption during tariff times when higher power prices are charged.
