Page 22: Wiring
Acuvim II Series Power Meter 2.3 Wiring There are four terminal strips at the back of the Acuvim II series meter, they are the voltage input terminal, current input terminal, power supply terminal and the communication port terminal. The three-phase voltage and current are represented by using 1, 2, and 3 respectively. These numbers have the same meaning as A, B, and C used in other literature.
Page 23: Voltage Input Wiring
Chapter 2: Installation terminal of the switch gear. An isolated transformer or EMC filter should be used in the power supply loop if there is a power quality issue with the power supply. Figure 2-17 - Power Supply Figure 2-18 - Power Supply with EMC Filter 2.3.2 Voltage Input Wiring Voltage Input Terminal The voltage input terminal strip consists of 4 input terminals: V1 (7), V2 (8), V3 (9), and VN (10).
Page 24 Acuvim II Series Power Meter The maximum voltage input for the Acuvim II series meter shall not exceed 400LN/690LL Vac RMS for three-phase or 400LN Vac RMS for single-phase. In high voltage systems a Potential Transformer (PT) must be used. The typical secondary output for PTs shall be over 100V or 120V.
Page 25 Chapter 2: Installation 3-Phase 3-Wire Delta Mode (3LL) 3-Phase 3-Wire Delta mode is commonly used in low voltage electric distribution systems. For voltages lower than 400LN/690LL, the voltage lines can be connected directly to the meters voltage input terminal as shown in Figure 2-20c. For high voltage systems (over 400LN/690LL), PTs (Potential Transformers) are required as shown in Figure 2-20d.
Page 26 Figure 2-20f - 1LN Direct Connection Vn Connection Vn is the reference point of the Acuvim II series meter voltage input. Low wire resistance helps improve the measurement accuracy. Different system wiring modes require Vn connection methods. Please refer to the wire diagram section for more details.
Page 27: Current Input Wiring
Chapter 2: Installation 2.3.3 Current Input Wiring Current Input Terminal Current Transformers (CTs) are required for most engineering applications. Typical current rating for the secondary side of the CT shall be 5A (standard) or 1A (optional); please refer to the ordering information appendix for further details.
Page 28 Acuvim II Series Power Meter The 3CT current wiring configuration can be used when either 3CTs are connected (as shown in Figure 2-22) or when 2 CTs are connected (as shown in Figure 2-23). In either case, there is current flowing through all three circuit terminals.

4.6 Harmonics and Power Quality Analysis 4.6.1 Harmonics & THD Acuvim II series meter can measure and analyze several power quality parameters which is useful for further analyzing the voltage and current signals measured by the meter. Total Harmonic Distortion: A ratio of the sum of powers in all harmonic components to power of the fundamental frequency.
Page 74: Amplitude And Angle
Acuvim II Series Power Meter Figure 4-11 - Individual Harmonic Reading 4.6.2 Amplitude and Angle This section provides users with the amplitude and phase angle details of the harmonics being measured by the meter. For example if the voltage input to the meter is 120V, and a harmonic reading of 10% for the 2nd order, the amplitude in this case will show 12V.
Page 75: Phase Angles
Chapter 4: Detailed Functions and Software 4.6.3 Phase Angles Phase angle indicates the angle between phase A voltage and other voltage/current parameters in a range from 0 to 360 degrees. These readings allows the users to analyze the phase angle difference between each phase and also determine if current/voltage are incorrectly out of phase, which tend to be related to wiring/installation issues with the meter.
Page 76: Sequence Component And Unbalance Analysis
Acuvim II Series Power Meter 4.6.4 Sequence Component and Unbalance Analysis Acuvim II series meter is able to perform sequential analysis for the input signal. The sequence components allow users to represent three-phase systems as individual into three single phase networks, where these networks can be described as the positive sequence, negative sequence and zero sequence.

Page 102 Acuvim II Series Power Meter The Current Month TOU is divided into two sections: Accumulated and Incremental. Current Month TOU (Accumulated): Refers to the TOU energy accumulated in the current month. Current Month TOU (Incremental): Refers to the TOU energy accumulated in this month minus the TOU energy accumulated in the prior month.
Page 103 Chapter 4: Detailed Functions and Software The TOU function displays the prior month TOU readings from the Acuview software. This allows users to compare the current month and previous month’s readings for billing and analytical purposes. These readings can be viewed in the software by clicking on the Prior Month TOU option under the Readings tab.
Page 104: Power Quality Event Logging And Waveform Capture
Acuvim II Series Power Meter When setup appropriately and when TOU is enabled, energy will be accumulated on a month- to-month basis. The current energy usage will be stored under Current Month TOU (or Current Accumulation Month TOU) and is divided up into different tariffs. When the next month (or counting period) starts, all Current Month TOU values will be moved to the Prior Month TOU (or Prior Accumulation Month TOU).
