PQ-D is an IEC 61000-4-30 Class A compliant power quality analyzer. It is designed for measuring and analyzing electrical parameters of low voltage distribution network. PQ-D is also able to measure the voltage of MV side of a distribution network. The internal GSM/GPRS modem allows remote monitoring and control of distribution network. It can also serve as a data-concentrator for ASELSAN's Mini-PQ devices via Power Line Communication (PLC) protocol.
