Why power quality matters
The quality of electrical power is crucial to business. As the advance Technologies of electrical tools and machinery are more sensitive to network disturbances (eg, voltage sags), leading to costly downtimes and production losses. Proactive steps are needed to maintain productivity and revenue.
Unoptimized power supplies can cause harmonics, unbalance, and low power factor. This can lead to high bills, overloading, and aging of electrical infrastructure, resulting in increased OPEX and equipment maintenance. To solve these issues, optimize power supplies to reduce expenses and improve system efficiency.
CBC offers power quality solutions to optimize operational continuity and prevent power supply interruptions in various industrial settings.
Poor power supply causes costly quality problems for industries in the EU. Voltage sags and short interruptions are the main causes, and they result in up to 90% of industry costs.

As a Power Quality experts, they see challenges hindering reliable power delivery. 
- Sags/swells
- Harmonic distortion and inter harmonics
- Micro cuts and outages
- spikes/transients
- Undervoltage/overvoltage
- Voltage imbalance (unbalance)
- Voltage fluctuations (flickering)
- Under/over frequency
- Poor power factor
Using techniques like equipment maintenance, load balancing, and high-quality power supplies can minimize these issues. We must prioritize power quality management and invest in modern power systems to achieve a more sustainable and reliable power system.

Downtime cost for business
A 2018 survey found that one in four companies experience a power outage at least once a month in the US and power outages are becoming the, unfortunate, norm for businesses.
Data centers: studies show that the average cost of a data center outage has grown to $8,851 per minute
Manufacturing: a recent survey found that more than a quarter of manufacturing businesses experienced an outage at least once a month in 2017, with 58 percent reporting an outage lasting longer than an hour. For large manufacturing companies a single hour of downtime tops the $5 million mark
Retail: a power outage in a supermarket could see hundreds of thousands of dollars lost by perishable goods being spoiled by lack of refrigeration. For instance, a supermarket in Pennsylvania lost power for more than a day in February 2019. The owner estimated losses to be up to $30,000 in merchandise; for large retailers, that cost is even higher, reaching upwards of $5 million.

Market Trends
Globally, power systems are experiencing a transition toward decarbonization of electricity production through the large-scale deployment of central and distributed energy resources (DERs) based on renewables, which are gradually replacing conventional thermal plants.
The connection of DERs to the power system is mainly achieved using power electronic converters that can have both a positive or negative effect on power quality, depending on the type of disturbances evaluated and the control strategies applied.
In the future, power quality is expected to be significantly affected by this shift towards carbon-free power generation. Other trends threaten to degrade power quality further: the integration of many power electronics devices, the use of power cables at all levels of voltage, the increasing amount of fluctuating energy production and, finally, a reduced overall electrical systems stability.
