It is a digital analyzer which is used for monitoring, measuring and recording of electrical parameters in low voltage and medium voltage. Its measurement circuit is designed for 1 phase and 3 phase systems with neutral conductor or without neutral conductor. Scanning frequency is 6.4 kHz in 50 Hz network frequency. Basic properties are high accuracy class, compact design and measuring of current and harmonic voltage values of each frequency. In virtue of functional variety of this analyzer, it is equivalent of about 13 different devices such as ammeter, voltmeter, active and reactive energy for 4 scale (consumption, feeding), frequency meter, harmonic analyzer and clock. This guarantee the costs such as design, installation and wiring would be lower than the state of using analogue measuring instruments. Another advantage is higher measurement accuracy. Selected measurement values are recorded with their dates and hours in some conditions such as energy cut and coming energy.
