Consumption and power quality

The quality of consumption and supply is essential to ensuring the proper operation of electrical installations, increase their useful life, and avoid production outages and indirect costs.

The appearance of new electronic systems in installations brings with it great improvements in the management and efficiency of the various electronic systems installed. Advances in HVAC, lighting, internal mobility systems (lifts, escalators and conveyor belts), electric vehicle charging systems and computer systems such as UPS, computers and monitors, have led to the incorporation of new electronic systems that improve their performance. However, this technology is a source of harmonics that causes a number of problems in electrical installations.

Another relevant aspect is how power quality is managed, since a voltage fault will directly affect your service, affecting all your customers and increasing your operating costs.

CONSUMPTION QUALITY

Avoid the problems caused by harmonics

Reduce the presence of harmonics in your installation by installing active filters to prevent trips of protective systems, improve the performance of your installation and ensure the satisfaction of your customers, employees and visitors.

POWER QUALITY

Ensure the power quality of your installation

Record the quality of the power supplied by the electric company and detect any incidents related to the voltage level supplied to ensure the proper operation of your installation, as per the IEC 61000-4-30 and EN 50160 standards.

CONSUMPTION QUALITY

Eliminate harmonics and ensure the smooth operation of your installation

The use of devices to convert current from AC to DC has spread to all types of sectors. These devices include all those that are installed in the electrical grid itself to automatically absorb non-sinusoidal currents.

Service facilities have become a routine user of this type of solution. These facilities include HVAC, lighting, internal mobility systems (lifts, escalators and conveyor belts), electric vehicle charging systems and computer systems such as UPS, computers and monitors. This technology is a source of harmonics that causes a number of problems in electrical installations.

These harmonics are circulating currents that are multiples of the base 50- or 60-Hz current, which can cause a series of issues in the electrical installation itself.

The most common effects they produce are:

- Trips of protective devices, causing unwanted service outages.

- Damage to computer systems, affecting the correct operation of payment systems.

- Degradation of insulation in equipment and wiring, leading to premature ageing.

- Overheating of conductors, transformers and motors, affecting their performance.

The installation of active filters solves the problems resulting from harmonic currents. This type of technology uses power electronics to inject currents upstream of the installation that are out of phase with the various harmonics that are measured in real time, thus mitigating their effects.

If the problem is caused by one or more loads connected in the same switchboard, the active filter would be installed just before this point, avoiding the circulation of harmful harmonics upstream and their adverse effects on the switchboard, protecting the rest of the installation.

SERVICE

Poor power quality reduces the satisfaction of customers and workers, directly affecting the level of service and profits.

POWER QUALITY

Set up your installation to prevent service outages

Poor voltage quality supplied by the electric company can directly affect the proper operation of your installation. One of the most relevant aspects to assess is the voltage level delivered, as this directly affects the correct functioning of your service. Poor voltage quality leads to a direct reduction in profits due to disruptions in both service and billing systems.

Another interesting point to evaluate is the impact of a power quality event, such as overvoltages, dips or interruptions. These events are defined as one-time faults caused by a problem in the distribution grid.

Circutor has a wide range of both fixed and portable power quality analyzers for detecting and recording power quality and transient events.

You can use this information to draw conclusions on the quality of the voltage in your installation and mitigate its impact or solve any problems resulting from poor power quality.

REGULATIONS

EN 50160

By installing power quality analyzers, you can prepare statistical reports, normally based on the EN 50160 quality standard, to ensure that the quality of the waveform supplied by the electric company complies with the minimum requirements. This way, you can be sure that the electric supply will always meet the quality standards, and not affect the performance of the installation.

IEC 61000-4-30

By installing power quality analyzers, you can identify sporadic quality events, as defined in IEC 61000-4-30, such as overvoltages, dips or interruptions, and quantify the type of event and its duration. You can use these devices to implement solutions that can mitigate the impact of poor power quality on production, as well as file claims with insurance companies for any associated damage.
