Analyzer and recorder of power quality parameters (multi-parameter multi-function device “Potential-REX”)

Analyzer and recorder of power quality parameters (multi-parameter multi-function device “Potential-REX”)Multi-parameter multi-function device “Potential-REX” is used to create global systems for management, control and analysis of the energy production conditions of any level in order to save energy and to control power system from a single center. It provides impossibility of unauthorized access.
The device records to the nonvolatile memory the current settings of 3-phase electric power line. Based on these data the analysis is carried out, according to algorithm, given by the consumer, the control signal to actuating devices is generated that can adjust the quality of electric energy, or in case of emergency can give a shutdown command. The device is intended for use on sites of energy consumption and conservation, and focused on the connection to the standard instrument transformers used in powerindustry.
Device functions
• measurement of electrical current and voltage parameters;
• oscilligraphy of voltage and current form during emergency situations in the device memory;
• recording of EE quality index (according to GOST 13109-97);
• data exchange with the module analog input and digital input/output;
• data exchange with external devices via interfaces RS485, RS-232, IRDA and Ethernet;
• transfer of accumulated data with a standard FLASH drive via USB;
• implementation of algorithms for relay protection
With direct connection to the REX-01 network allows you to measure and to record;
• AC voltage ranges from 0 to 500V (effective value);
