Transient Overvoltage
Transient overvoltage refers to a pulse voltage with a peak value of up to 20,000V, with a duration ranging between one millionth and ten thousandth of a second. Its primary causes and potential damage are similar to high-voltage sharp pulses, although the solutions may differ.
2) Voltage Sag:
Voltage sag refers to a low voltage condition where the effective value of the municipal power voltage is between 80% and 85% of the rated value, and lasts for one to several cycles. Starting large equipment, large electric motors, or connecting large power transformers can cause this issue.
3) Surge Protection:
Surge refers to the output voltage being more than 110% of its rated value, with a duration of one or more cycles. Surges are primarily caused by high voltages generated when large electrical equipment connected to the power grid is turned off, resulting from the sudden unloading of the grid. 36V aviation power supply, 400HZ variable frequency power supply, 115/200V power supply, 27V DC power supply, 400HZ power supply, aviation power supply
4) Continuous Low Voltage:
Continuous low voltage refers to the effective value of the city power voltage being below the rated value for an extended period. Causes include the startup of large equipment, switching of main power lines, starting of large motors, and line overload. If you experience similar issues with your city power supply, we recommend that you have the power department measure parameters such as frequency, waveform, and voltage of the power grid to confirm if there are any of the aforementioned issues.
5) Frequency Offset:
Frequency deviation refers to the change in the city power frequency exceeding 3Hz. This is mainly caused by the unstable operation of emergency generators or by power supply from sources with unstable frequency.
6) Wire Noise:
Cable noise refers to radio frequency interference (RFI), electromagnetic interference (EFI), and various other high-frequency interferences. The operation of motors, relay actions, motor controller functions, broadcast emissions, microwave radiation, and electrical storms can all cause cable noise interference.
7) High-Voltage Pulsed Power
High-voltage sharp pulses refer to voltages reaching 6000V with durations ranging from one ten-thousandth of a second to half a cycle (10ms). They are primarily generated by arc discharge, static discharge, or switching operations of large electrical equipment.
