Chapter 1 Introduction
Overview
Integrated Measurements of Various Electrical Parameters
Accura 3300 is a high accuracy digital power meter tailored for reliable measurements and
accurate analysis of power consumption. Installed in factories, power and generator panels in
buildings, etc, the device performs integrated measurements of various power parameters,
including voltage, current, power, frequency, and power factor.
Accurate Measurements
Measurement accuracy is a key factor that determines the reliability of energy management
systems. Low measurement accuracy causes inconsistency between the energy of the incoming
feeder and the sum of energy measured on the load side. It makes it difficult to perform reliable
energy management. Accura 3300 provides highly accurate measurements of voltage and
current(
±
0.2% of reading) and meets IEC 62053-22 class 0.5S for power and energy
measurements. It helps to address problems caused by measurement errors and allows for
efficient energy management.
Power Quality Data Available
Accura 3300 provides the information of power qualities, such as voltage/current THD, harmonic
analysis, and k factor.
Proven Safety and Reliability with CE/UL Certifications
Accura 3300’s inte
rnal and external structures(the product and circuit design) meet safety
requirements for CE(IEC 61010) and UL(UL 61010-2, 2nd edition) standards. A busbar is
provided with the product for easier wiring of CTs when installing the product. The busbar
minimizes fire hazards by ensuring safety under an overcurrent condition.
