Power line analyser PLA33 is a modern device for
multifunction monitoring of main electrical parameters in
three­phase network. Device measures parameters
according to norm IEC 61000­4­30 and it is ideal for very
precise power management.
Internal memory and communication interface define the
PLA33 being used as power monitoring recorder or part of
SCADA systems.
• 4 quadrant continual measurement
• monitoring of U in every phase and phase­phase
• monitoring of I in every phase
• calculated current in neutral wire
• system frequency
• THD U and THD I
• odd harmonics of U and I till 19th (L1, L2, L3)
• power factor (L1) and cosφ (L1, L2, L3)
• P+/­, Q+/­, S (L1, L2, L3, ∑)
• Eactive+/­, Ereactive+/­ (L1, L2, L3, ∑)
• internal current transformers ICT
• measurement according the standard IEC 61000­4­30
• measuring phase­phase voltage from 0 ... 520 VAC
• auxiliary power supply
• memory for recording of maximums / minimums
• memory for recording of 20 power cut events
• internal real­time clock
• communication interface RS485 with Modbus RTU protocol
• internal memory 512MB for measured parameters recording
• minimum internal memory sampling period 60s (AVG value)
• two independent digital input / output
