ENERGY AUDIT AND DEVIATIONS OF POWER QUALITY INDICATORS
Power quality analysis
is a modern, most objective, fast, and convenient way to get complete information about the state of the power system and identify any problems associated with interruptions in the operation of electrical installations!
Deviations of the power quality indicators from the standardized values lead to a deterioration in the operating conditions of electrical equipment and its premature wear or failure.
For example, it affects the operation of asynchronous motors, which are widely used in many areas of the economy and the economy. With a decrease in the supply voltage, the torque on the motor shaft decreases, which under certain conditions can lead to a complete stop of the motor. In addition, undervoltage reduces the starting torque, which worsens the starting conditions of the engine. The increased voltage at the motor terminals leads to an increase in the consumed reactive power. On average, for each percentage increase in the network voltage, the reactive power consumption increases by 3%.
Significantly affect the operation of lighting devices and electronic equipment. Blinking of light sources (flicker effect) causes an unpleasant psychological effect, fatigue of vision and the body as a whole. This leads to a decrease in labor productivity, and in some cases to injury. With significant voltage fluctuations (more than 15%), the conditions for the normal operation of electric motors may be violated, the contacts of magnetic starters may fall off with a corresponding shutdown of the running motors. Voltage fluctuations with a swing of 10-15% can lead to failure of the capacitor banks.
Voltage harmonic distortion
They lead to additional heating in transformers, create additional losses in busbars, cause overheating and destruction of neutral working conductors, worsen working conditions and disable capacitor banks.
Lead to equipment failures, malfunction of automation devices, relay protection, and loss of information. Special attention is paid to this problem by various data centers, scientific laboratories, and other facilities for which data preservation is a primary task.
All of the above deviations can lead to varying degrees of severity of the damage. Therefore, knowledge of the real indicators of the quality of electricity at the enterprise is really important and will allow you to detect and localize problem areas. Using modern measuring devices, and specialists, our company will help to detect and identify problems and threats. The range of measured values depends on the purpose of the monitoring.
