Page 56: Basic Analog Measurements
KW320 Power Meter The KW320 series meter contains advanced metering tools and is able to measure a multitude of power, energy and power quality parameters. Some advanced functions may not be accessible directly from the meter front; therefore, every meter comes with a powerful software that helps access the information.
Page 57 Chapter 4: Functions and Software Demand: This meter consists of several types of demand calculation: total active power demand, total reactive power demand, total apparent power demand, phase A current demand, phase B current demand, and phase C current demand. When demand is reset, demand memory registers are set as 0.
Page 58 KW320 Power Meter Fig 4-2 Energy and Power Quality Parameters Current Direction Adjustment: Under normal circumstances, current flows from input terminal 1 to terminal 2 (i.e. from I11 to I12 for phase A current); however, current may flow in the opposite direction due to incorrect wiring setup.
Page 59: Max/Min
Fig 4-3 Max/Min 4.2 Max/Min KW320 series meter logs maximum and minimum value statistics for phase/ line voltages, current, power, reactive power, apparent power, power factor, frequency, demand, unbalance factor, THD as well as the time they occur. All data is stored in nonvolatile memory so that statistic information can be preserved even when meter is shut off.
Page 60: Harmonics And Power Quality Analysis
They are shown in Fig 4-4. Sequence component and unbalance analysis: KW320 series meter is able to perform sequential analysis for the input signal. It looks at the positive sequence, negative sequence and zero sequence of 73 the fundamental frequency and performs unbalance analysis for voltage and current.
Page 61: Over/Under Limit Alarming
Chapter 4: Functions and Software 4.4 Over/Under Limit Alarming KW320 series meter has over/under limit alarming capabilites. When the monitored parameter goes over/under the preset limit and stays at the level over the preset amount of time delay, the over/under limit alarm will be triggered. The over/under limit value and its time stamp will be recorded in the 74-alarming log.
Page 62 KW320 Power Meter Single Alarming Group Setting: Table 4-1 indicates the first group of settings, there are 16 groups in total with the same format. Address Parameter Range Property 104EH First group: parameter code 0~79 104FH First group: comparison mode 1: larger | 2: equal | 3:smaller 1050H First group: setpoint value...
Page 63 Chapter 4: Functions and Software register. The corresponding bit must be set to "1" in order to activate the alarm channel. Logic "AND" between alarm setting: The 16 alarming records in the meter are divided into 8 pairs. Each pair has two alarm groups. The two groups can be logically “AND” by controlling the logic check box.
Page 64 “Global alarming enable (1046H)” set to 1 to enable over/under limit alarming. Records of Alarming Event: KW320 series meter has built in alarm logging capabilities. 16 entries can be recorded in total. The record sequence of these entries do not depend on the sequence of the 16 alarm channels.
Page 65 Chapter 4: Functions and Software or not, 1 means enabled and 0 means not. Bit0 indicates whether alarming has occured or recovered, 1 means occurred and 0 means recovered. Undefined bits are 0. “Parameter code” specifies the monitored parameter. “Value” shows the recorded value of the selected parameter when an alarm is triggered and when it recovers.
Page 66: Data Logging
KW320 Power Meter Fig 4-7 Basic settings 4.5 Data Logging The KW320 and KW320Q meter provides data logging that records the data at a set interval. This meter has 8 GB of memory which gives it extensive datalogging capabilities. It has a real- time clock that allows logs to be time-stamped when log events are created.
Page 67 Chapter 4: Functions and Software Fig 4-8 The data log 1 setting Having three sets of historical logs provides you with the option of programming each log with unique parameters. For example, you can program Historical Log 1 to record measured values parameters (for example, Frequency, Voltage, Current), Log 2 to record energy values parameters, and Log 3 to record power quality parameters.
Page 68 KW320 Power Meter • THD Volts CN/CA (THD, average THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN, CF and THFF of Volts CN/CA) • THD IA (THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN, KF of IA) • THD IB (THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN, KF of IB) •...
Page 69 Chapter 4: Functions and Software Three Modes of historical log: A. Mode1: if correctly set historical log, can record without setting date and time, depending on first-in first-out recycling log. B. Mode2: if correctly set historical log, as set date and time, can record within begin to end time.
Page 70: Power Quality Event Logging And Waveform Capture
KW320 Power Meter The "read one window" method allows you to access and read a specific log location at an offset from the first log. The "window record num" is the maximum number of record entries the software can read at a time, it is calculated by 246 / Record Size. The larger this number is, the faster data can be retrieved.
Page 71 Chapter 4: Functions and Software Event Logging Triggering Conditions: • Voltage Sag When any phase of the three-phase voltage is lower than the set value (voltage rated value x threshold %), there will be a voltage sag event. When one phase voltage sag happens, the other phase will not respond to voltage sag event logging.
Page 72 KW320 Power Meter Event Log Retrieve: When a new event log commences, the newest event number address (0X8CFDH) contains the newest event number. When the log is being retrieved, the starting event log number (0X8CFEH) and the event quantity for 96 each retrieve (0X8CFF) must be set correctly. It must be ensured that the starting number of event log should equal or smaller than the newest log number.
Page 73 Chapter 4: Functions and Software Waveform Capture KW320Q can record 100 groups of voltage and current waveform data at a sampling rate of 64 points per cycle. It provides the captured waveform of 10 cycles before and after the triggering point (including U1, U2, U3, I1, I2, I3).
Page 74 KW320 Power Meter Waveform Order: • Before triggering point 10 U1 waveforms, 10 U2 waveforms, 10 U3 waveforms, 10 I1 waveforms, 10 I2 waveforms, 10 I3 waveforms. • After triggering point 10 U1 waveforms, 10 U2 waveforms, 10 U3 waveforms, 10 I1 waveforms, 10 I2 waveforms, 10 I3 waveforms.
Page 75 Chapter 4: Functions and Software enabled, both event logging and waveform capture will be implemented at the same time once a voltage sag happens. Voltage Swell Triggering As mentioned in Voltage Swell event logging, when Voltage Swell Triggering Waveform is enabled, both event logging and waveform capture will be implemented at the same time once a voltage swell happens.
Page 76 KW320 Power Meter Second retrieving method is retrieving all waveforms data. When 0x8E01H (Waveform Group Number) is set to 1~121, each time only one group data of each number will be retrieved, then Waveform Group Number for Retrieving (8E01H) will automatically add 1 after retrieving. At next time, new Waveform Group Number will be retrieved.

KW320 Power Meter Fig 4-12 Note: When selecting 400Hz type, not support event logging and wave capture. 4.7 Sealing Function The panel with seal, which has sealed key control, is different with one without seal. When the seal is in opened status, functions are same like normal meters. But when the seal is in sealed status, some functions of meters, which include parameters blocked by seal and optional parameters, will be blocked.
Page 79 Chapter 4: Functions and Software Addresses about seal function are 101EH and 101FH. Address 101EH is about parameters blocked by seal, which can be configured by users. These setting will be valid only when seal is in sealed status. Address 101FH is about if seal function is valid. When the panel is normal one, or the seal panel is in invalid sealed status, this address will show seal is open.
