In order to optimize our range of fixed Power Factor Correction Systems, the MICROfix have recently been revised.

Below is the range of equipment which will be listed in the 2020 catalogue and price list. Starting from January 27th 2020, only these models will be available for sale (the other sizes of the previous range will be discontinued).

PFC restyling

Starting from January 2020, our Power Factor Correction Systems will be progressively restyled and their look will be updated according to our new company image.

The labelling of the systems, regulators and thyristor switches will be blue, as per the examples below.

Thanks to the technical characteristics of its columnar voltage regulators, ORTEA is able to design and manufacture high power voltage stabilisers (up to 6000kVA at 400V).

The quality and reliability of her equipment has enabled ORTEA to secure numerous orders; in particular, several XXL stabilizers were produced in October: on the right side of the picture we see 3 units of 1250kVA with bypass and automatic circuit breakers, and two of 800kVA for a total power of over 5MVA, ready to be shipped in Africa and North America.

Everybody boasts they can do this … ORTEA really manufactures them!

Three SAG compensators OXYGEN (for a total power of 800kVA), destined to one of the most important European International Airports, are currently being tested in our laboratory. On customer’s request, the cabinets are painted yellow, a color that does not go unnoticed. Once installed, they will provide an important contribution to the Power Quality efficiency of the hub facilities, by counteracting the effects of voltage SAGs.

On October 9th, in cooperation with Company Richard Equipment, a trade seminar about ORTEA stabilisers was held at the Hotel Casino Du Port in Dakar, focusing on our "cost-effective" range Lyra & Polaris.

The participation and involvement of the attendees was wide.

We thank our distributor Richard Equipment and our Africa Regional Director Paul-Marie Dable for making this event possible.

Being aware of the importance of ensuring qualified technical presence everywhere, ORTEA SpA keeps allocating resources for engineers training, enabling them to operate efficiently on voltage stabilisers, transformers and power-factor correction systems installed worldwide.

The first 2019 training session has just come to an end: the ORTEA team, by means of theoretical and practical learning sessions, has given detailed information to the attendees, which will allow them to maintain and repair the installed units. The participants (about thirty people in total) came from different Countries: Colombia, Egypt, the Philippines, Germany, Pakistan, Poland, Singapore, Sudan and Turkey.

The session in French will be held in September.

Power Quality is gaining increasing attention in the electric power industry. The consumer of electrical energy requires electric power with a certain quality, but loads can have a negative impact on the electrical system and are thus also subject to an assessment in terms of quality. Power quality is therefore intrinsically linked to the interaction between the electrical system and loads and must take into account both the voltage quality and power quality.

Possible consequences of low power quality that affect business costs are:

• Power failures (Release switches, fuses blowing).
• Breakdowns or malfunctions of machines.
• Overheating of machines (transformers, motors, etc.) leading to reduced useful life.
• Damage to sensitive equipment (computers, production line control systems, etc.).
• Electronic communication interference.
• Increased distribution system losses.
• The need to oversize systems to cope with additional electric stress, resulting in higher installation and operational costs.
• Luminosity flickering

Interruption of production due to these impacts of low power quality entails high costs due to production loss and the associated waste. For the Industrial sector, the estimated costs due to poor power quality represent 4% of turnover (Source: Studio Leonardo Energy). The impact of production interruptions is greatest in companies with continuous production.

Among the main causes of poor power quality in low voltage are:

• Voltage sags, because equipment operates less efficiently and can stop.
• Harmonic pollution, which causes additional stress on the networks and systems, causing them to operate less efficiently.
• Excessive reactive power, because it charges useless power to the system.

The solutions vary for each cause. The voltage sags can be eliminated with a sag compensator, which ensures a voltage output at a nominal value. Reduced productivity, loss of data, loss of security, and machine breakdowns are only some of the problems caused by an unstable power supply that can be solved with a voltage sag compensator.

Harmonic pollution is caused by large amounts of non-linear consumption (from inverters, soft starters, rectifiers, power electronics, non-filament lighting, presses, etc.). Such devices deform the electrical current causing disturbances and problems to the system. Harmonic pollution is solved by active filters that are capable of eliminating the current harmonics in the system by measuring and injecting the same current, but in the opposite phase.

Excessive reactive power is regulated by a power factor correction system, which not only avoids any penalties due to excessive reactive energy, but reduces the “unnecessary” electrical current that flows into the lines and power components, yielding substantial benefits, such as reducing voltage drops along the lines and leakages due to the Joule effect.

Loads operated by electronic devices are increasingly adopted in more and more industrial and commercial applications such as: Variable Speed Drives, rectifiers, UPS systems, DC power supplies, welding machines, computers, TV, energy efficient lamps, photocopiers.

These loads generate waveform distortions that become threat for network components.

In particular voltage and current harmonics, where the latter is the more dangerous, generate a series of problems, like:

• Cable overheating
• Undue tripping of circuit breakers
• Blowing of fuses
• Capacitor overloading and network resonance
• Neutral cable overload
• Transformer premature ageing
• Electronic appliances disturbance.

These effects are seldom related to harmonic current and voltage distortion, while effective remedy for harmonics are passive and active filters. Active filters achieve much higher levels of efficiency in harmonics cleaning the first does not:

ACTIVE FILTER

• it can compensate many harmonic currents simultaneously (ICAR FA40 up to the 50°)
• It does not saturate or overload
• It is uninfluenced by the network conditions (capacitance/Inductances)
• it hasn’t capacitance
• it is extremely flexible, it can target few harmonic currents
• It can compensate power factor, even at high speed
• it can compensate unbalanced loads
• it attenuates voltage flicker
• it can be set in parallel with other filters, even at later stages
• it automatically and semalessly adjustes to the load

PASSIVE FILTER

• it can compensate only one or very few harmonic current
• it is extremely difficult to compensate few harmonics at the same time.
• it can saturate or be overloaded
• it is influenced by the network as for the existing capacitance and inductance
• it is a capacitive load, hence improve power factor.
• it is fix and not adjustable
• it can be ON/OFF, or in steps.
