General: PD319-2 Series Multifunctional Harmonic Analyzer is designed for measuring electic parameters, harmonics, multi-rates energy, power quality, S.O.E event reording and communication. They are applied in electric energy management power monitoring and controls, power substation automation, smart building and switchgears, etc. PD319-2 Series Multifunctional Harmonic Analyzer is designed according to (DL/T614-1997, GB/T17883-1999, GB/T17882-1999, DL/T645-1997, GB/T15284-2002, GB/T14549-1993) . Features: 1. The meters can measure 3-phase voltage, 3-phase current, active and reactive power of each phase, total active power, total reactive power, power factor, frequency, 4 quadrant energy. They can measure multi-rate power. 2. The meters can measure the voltage in power network, the harmonic obtained rate of 2 31 times of the current, as well as the total harmonic distortion rate THD. (3 CTs is required). 3. The meters analyze the network voltage, the ponderance and imbalance of current order (positive and negative)(3 CTs is required). 4. With 2 loops of switch input, adoptiing trunk crunode resistance signal input mode. 5. With 2 loops of photo coupler relay switch output, and alarm indication in all environment so as to protect the output control function. 6. The meter supply the active and reactive power pulse output. 7. RS485 communication interface under MODBUS-RTU protocol. 8. The meters can record 20 pieces SOE event.
