Undervoltage conditions are usually be caused by undersized or overloaded utility and facility transformers. During peak demand periods and/or when the utility is experiencing problems, the demand for power exceeds the capability of the transformer and as a result the voltage drops.

< 50. < 120. Low risk. The International Electrotechnical Commission (IEC) defines supply system low voltage as voltage in the range 50 to 1000 V AC or 120 to 1500 V DC. In electrical power systems low voltage most commonly refers to the mainsvoltages as used by domestic and light industrial and commercial consumers.

Bus undervoltage protection. The undervoltage relay may either alarm or tripvoltage-sensitive loads, such as induction motors, whenever the line voltage drops below the calibrated setting. A time-delay relay is normally used to enable it to ride through momentary sags and thus prevent nuisance operation.

Sitri16 wrote:What is phase voltage?

Line voltage (line-to-line voltage) in a polyphase system is the voltage between two given phases.On the other hand, Phase voltage is the voltage between the given phase and neutral. Note that neutral is available in star connection but not delta connection.

High voltage is defined by the DOE Electrical Safety Guidelines as over 600 volts. Generally considered to be a wire or cable with an operating voltage of over 600 volts. Any electric potential capable of producing breakdown in air at STP, or around 600volts. A voltage higher than that used for power distribution.

High voltage starts at the point where designers have to consider additional technical issues, and where there are significantly fewer component suppliers to choose from.
Technical Issues: Certainly, for most engineers, high voltage is different voltage. It's no longer engineering-as-usual. Other variables enter into the design and manufacturing processes. You need to take into consideration creepage distance, insulation thickness, corona and geometrical arrangement. It's no longer a good idea to use your finger to see which component is running hot. Components exhibit unexpected behavior, like resistors that change value as a function of applied voltage. Component Supplier Issues: Designers need to be more careful in vendor selection. That's because there aren't tons of suppliers, and the technology isn't as well known. Thus, there are larger differences in quality and reliability among high voltage manufacturers. For example, if you need a 5V power supply, there are hundreds of companies that will make them. But if you need, say, 100V or 10,000V, there are only a handful. And of that handful, there is only a couple that makes high quality, reliable supplies.
