The polyphase electronic electricity meters of E3S types are used for measurement of active and reactive electric energy in three-phase voltage networks  of frequency 50 Hz or 60 Hz. They can be  used as basic components of automated power monitoring and regulation. They are connected directly or through instrument transformers (for semi-direct and indirect connections). The measuring system of electronic electricity meters E3S meets the requirements on measurement in accuracy class1 and 2 in compliance with the standards STN EN 62053-21 and STN EN 62052-11 and STN IEC measurement in accuracy class1 and 2 in compliance with the standards STN EN 62053-23. The current and voltage ranges, the terminal connections as well as execution of terminal block is supplied in accordance with customer request.

Main advantages of KRIZIK meters:

- higher accuracy of electrical energy measurement  compared to electromechanical electricity    meters
- a wide range of measured currents
- low value of starting current
- low value of power losses in the current and voltage circuit
- reliable and simple connection to the network
- several precautions against tampering
