It Programmable Transducer of 3-Phase Power Network Parameters Special Features Measurement and conversion of power network parameters in 4-wire balanced or unbalanced systems. Tetraquadran􀀏c energy measurement (Ep+, Ep-, EQL, EQc). Measurement of 15, 30 or 60 minutes’ mean acti􀀏ve power (synchroniza􀀏on by an internal clock or a walking window) with the archiving func􀀏on of 1000 last samples. Programmable current and voltage transformer ra􀀏os. Programmable parameters through the RS-485 interface or USB when using the free LPCon program. RS-485 communica􀀏on interface with MODBUS protocol. Detec􀀏on and signalling of incorrect phase sequence. THD measurement.
