Why Is Power Quality Important?
The Power Grid Can Also Get Sick
People will suffer from various diseases, such as colds, pneumonia, heart disease, etc. The power grid, like humans, will also get sick. So what diseases will the power grid suffer from?
- REACTIVE POWER
Reactive power is the energy needed to establish an AC electromagnetic field. If it cannot be compensated locally at the load, it must be drawn from the grid via transmission lines, resulting in additional energy losses.
2. HARMONIC
Nonlinear loads generate harmonic currents that distort voltage and current waveforms, increasing losses, heat, and reducing equipment lifespan. Severe harmonics can damage equipment.
3. THREE PHASE IMBALANCE
400V low-voltage systems often have uneven single-phase loads, causing three-phase imbalance, which increases transformer losses and wastes capacity.
4. VOLTAGE FLUCTUATIONS
High-power load switching causes reactive power shocks, leading to voltage dips or surges that disrupt equipment operation.

Symptoms After Grid Illness
People who catch a cold may have a fever, cough, runny nose, and lack of energy. So what are the effects of a power grid illness?
Many inductive devices in the power system generate reactive power, lowering the power factor. The power supply department sets power factor requirements for loads, and users with low power factors are fined through rate adjustments.
Third and fifth harmonic currents can overload the neutral line, causing heating and safety hazards.
Harmonics can cause capacitor overvoltage, overheating, and damage, potentially leading to failure of compensation devices and system outages.
Reactive power and harmonic currents increase total power demand, reducing transformer capacity. Managing these factors improves transformer efficiency and reduces losses.
Harmonics can disrupt relay protection signals, causing device malfunctions and ineffective protection.
Harmonics can affect user devices, leading to display inaccuracies, touch failures, and malfunctions in precision equipment like medical or CNC devices.
