Care Labs provides power quality analysis to businesses all over Australia. Our goal is to protect your electrical installations, electrical equipment, and appliances from all possible issues caused by fluctuations in the power supply.
Many companies as well as an increasing number of private customers, today have a variety of data collection, monitoring, and instrumentation equipment that is highly vulnerable to fluctuations in the power supply. While most electrical products are designed to withstand certain supply variations, very few are designed to withstand the spectrum of voltage fluctuations that are a common characteristic of distributed electricity.
Care Labs professional experts will assist in resolving power quality issues in the areas of equipment installation, control, protection, and power conditioning. The service will comprise – obtaining detailed information about your appliance that can help you consider the sources of supply fluctuations, the risks to specific equipment, and the available safety measures as per the Australian Standard – AS/NZS 61000.
All electrical networks suffer supply interruptions, which occur more often when power lines are disrupted by storms, calamities, or accidents. Power supply fluctuation is quite natural.
There are three categories of fluctuations, disturbances, and distortions in the characteristics of power supplied by an electricity network:
1.Frequency deviations – where a frequency is beyond the natural range of frequency.
2.Voltage disturbances – where the voltage shape is preserved but the voltage amplitude is beyond the normal
2.1 Short duration variations include voltage sag (dip) and voltage swells of up to one minute in duration.
2.2 Long duration fluctuations include prolonged under voltages and overvoltage lasting for more than one minute.
2.3 Unbalanced voltage – where the load is improperly distributed across the phases leading to significant heating of the equipment.
2.4 Differences in voltage between neutral and earth
3.Disturbances caused by distortion – where the voltage shape is non-uniform or non-sinusoidal.
3.1 Waveform distortions: Harmonics and inter-harmonics that result in the heating up of devices, increased losses, inefficient power consumption, and resonance issues.
3.2 Transients that occur for less than one-tenth of a second in duration but are capable of degrading the contact surface of switches, induce inefficiency in the system and lead to pre-mature failure of motor drives and control.
Various power quality disturbances require different approaches to be identified, few of these approaches are:
