Measurement of electrical energy is the first step in providing quality and efficient energy in the modern world where electricity is indispensable. Problems in energy quality motors, power electronics systems, lighting systems and so on. It can cause damage to all electrical systems.

Energy analysts are a microprocessor -based measuring instrument that enables the analysis of the basic parameters of electrical energy to the user. Sigma Electrical Energy Analysts LCD display can be seen instantly with various energy parameters; It also provides remote access with its storage and communication feature.

Harmonic current and tensions are one of the main factors that disrupt the quality of energy. Systems with semiconductor circuit elements such as capacitors and motor drivers cause harmonic currents from the network. Harmonic current and voltages begin to be harmful when they increase above certain levels (20 %for current harmonics and 5 %for voltage harmonics). The main damages are the voltage imbalance taken from the source, the deterioration of electronic devices, the heating of the cables, the system to resonance, etc..

Another issue that requires the monitoring and control of electrical energy is to keep reactive power components below certain limits to prevent criminal conditions. In addition to reactive rates, current and voltage imbalance also poses serious problems, phase-phase current-voltages phase-neutral current and tensions can cause system failures, especially engines.
