Electrical network analyzer PLA33

harmonicfor integrationdigital

The power line analyser for accurate monitoring of main electrical parameters in three-phase or single-phase networks. The instrument measures continuous voltage and current according to the norm EN 61000-4-30. Thanks to precise measurement and a high sampling rate, it is also ideal for particular measuring points in electrical energy monitoring systems. The communication interface RS485 with Modbus RTU protocol predefine PLA33 can be used as a measuring point in SCADA systems. Harmonics measurement THDU and THDI are calculated from harmonics range up to 40th harmonics. Device measures and shows also particular odd harmonics of voltage and current up to 19th harmonics. Energy meter PLA33 has 6 internal energy meters for consumed and supply active, reactive inductive and reactive capacitive energy. Each energy meter can be linked to the digital output and provides information by pulses to another instruments such as peak demand controllers etc. Display PLA33 has LCD display with back-light. All values are identified by parameter name and real variables. Monitoring and setup menu is easy to understand thanks to logic shortcuts and symbolic names.
