Frequently Asked Questions
What is the difference between OTSOSMART, OTSOPRO and OTSOMAX?
OTSOSMART is the basic solution for measuring and monitoring power quality and compensating for reactive power (input/output). OTSOPRO is based on OTSOSMART, but also includes harmonic filtering (3-13) for improved grid stability. OTSOMAX is the most efficient option for large industrial applications and harsh conditions, filtering out all harmonics in the frequency range (3-51)
How does OTSOPRO improve power quality?
OTSOPRO filters low-frequency harmonics (3 to 13) that cause interference to motors and sensitive equipment. This reduces downtime, overloads and unnecessary wear.
Can the OTSO system reduce electricity costs?
Yes. By correcting the power factor and reducing the reactive power, the system reduces the additional fees charged by the network operator. At the same time, the service life of the equipment (incl. transformers) is extended and maintenance costs are reduced.
Are OTSO solutions suitable for both new construction and renovation projects?
Absolutely. The system can be installed both in a new property and in an existing electrical grid. The installation is done in parallel to the main switchboard, and a power outage is usually not necessary.
How do harmonics affect devices?
Harmonics often cause overheating, premature wear and unexplained downtime in motors, UPSs and transformers, for example. OTSOPRO and OTSOMAX eliminate these problems and make the network more stable.
How often does the system need maintenance?
OTSO systems are virtually maintenance-free. Only the filter is usually cleaned 1–2 times a year, more often in dusty conditions.
How quickly will the results appear after installation?
The effects are immediately visible as an improvement in power quality. From the OTSOSMART portal, you can monitor measurement data in real time immediately after commissioning.
Why is power quality important for companies?
Poor quality electricity can lead to costly downtime, equipment breakdowns and additional energy costs. The OTSO system protects your investment, reduces risks and improves the reliability of the entire network.
