HARMONIC DISTORTION

Series 9 and Ferro UPSs Address Harmonics

Harmonics are Everywhere

Case Study - Electronics:

A large computer chip manufacturer had frequent untraceable errors in a product testing lab. This meant that the reason a test failed could not be confirmed or repeated. Was there a problem with the product, or was the test environment causing these errors? Measurements revealed excessive levels of harmonic distortion in the voltage supplied to their equipment. When the harmonic distortion problem was treated, the untraceable errors disappeared.

Case Study - Broadcasting:

A broadcaster was experiencing lock-ups of mixing boards and program corruption of video routers. On one occasion, during a live broadcast, a video mixer became inoperable resulting in the completion of the broadcast from a single camera position. Measurements revealed excessive levels of harmonic distortion in the voltage supplied to this equipment. When the harmonic distortion was removed the operational problems disappeared.

There are many similar examples where electronic equipment such as computers, telecommunications and broadcast equipment suffers the consequences of harmonic distortion. The reality is that this equipment is sensitive to the quality of the voltage waveform. In order to ensure the proper operation of this equipment, voltage must be free of distortion.

Power Consultants Warn:

•A site may not have an overload or unsafe condition now, but the owner needs to be on guard against this harmonic threat.

Effects of Harmonics

•High levels of harmonics result in erratic or subtle malfunctions of equipment that can have serious consequences.

•Overheating could cause overvoltage damage and premature failure to computers and office equipment.

•High harmonic levels can fool certain control circuits into erroneous operation. CPU clock timing operations can be falsely triggered.

•Intermittent electrical noise is intense enough to corrupt digital signals and cause malfunctions.

•Distortion of voltage is severe enough to impair ride-through capabilities of computers and related equipment.

Competitor Response

•Harmonic voltages have virtually no effect on modern computers, but can cause overheating in some cases.

•The UPS may operate in backup mode much more often than usual due to the poor quality of the AC power source (source with severe line voltage distortion).

Independent Evaluation of Competitor Series 5 UPS

•The APC Smart-UPS®momentarily transfers to inverter for almost any voltage anomaly.

•UPS equipment worked properly with harmonic distortion levels below 5% THD. As distortion levels increased, more interaction was noted. At 8.66% THD, the competitor UPS would not operate from the test voltage until the sensitivity switch on the back of the unit was set to a more tolerant position.

What Does It Mean?

1.Harmonics will cause sensitive equipment to crash and fail prematurely.

2.Line-interactive technology may not protect the sensitive equipment from harmonics.

3. Online and Ferro UPSs are recommended to protect sensitive equipment from harmonics.
