PowerGuide 4400 description
4400 Firmware
The Dranetz quality meter/monitor. This cutting-edge power quality instrument is designed with a color liquid crystal display (LCD) 1/4 VGA, using touch screen technology. It can monitor, record and display data on four voltage channels and four current channels simultaneously.
The 4400 is designed to meet both the IEEE 1159 and IEC 61000-4-30 Class A standards for accuracy and measurement requirements. It can also monitor EN50160 compliance based on the EN (European) Standards. The statistical package called Quality of Supply (QOS) is built into the 4400, with monitoring and setup protocols set to determine voltage measurement compliance required for EN50160 monitoring. European standard EN50160 requires that measurement parameters must be within a specified percentage for 95% of the time.
The firmware for the 4400 is contained on internal FLASH memory. It has an operating system capable of performing multiple applications. When an updated version of the firmware is released, the user can upgrade the internal program by putting the latest 4400 firmware program card in the appropriate slot of the mainframe. See page 1-10
for instructions on how to upgrade the 4400 firmware from a data card.
The 4400 firmware can monitor power quality phenomena for troubleshooting and/or compliance purposes. It can record inrush conditions, carry out long-term statistical studies to establish performance baselines, and perform field-based equipment testing and evaluation for commissioning and maintenance. The firmware integrates an intuitive instrument setup procedure to ensure the capture of all relevant data for additional post process analysis, report writing, and data archiving using other compatible Dranetz software applications such as NodeLink

4400 Features
Touch screen function
Scope mode
Meter mode
Harmonics
All 4400 functions described below are operable using a color LCD touch screen technology. Users may use a finger and/or a PDA stylus to apply pressure to the LCD screen to result in touch screen recognition. The touch screen display is also workable with lineman gloves on. Touch screen buttons will appear in reverse-video to show visual feedback of contact along with audible feedback. In order to reduce power consumption, the backlight of the LCD screen times-out after a specified programmable time of no user activity. The backlight reactivates by touching any part of the screen.
Scope mode functions as an oscilloscope, displaying real-time waveforms of voltage and current for up to eight channels simultaneously, with one second update rate. The colors of waveform display are user programmable. Scope mode also provides a textual display of rms values, division for axis values, and frequency.
Meter mode functions as a true rms voltmeter and a true rms clamp-on ammeter. Voltage and current measurements, along with other calculated parameters, are displayed on the Meter mode screens in both textual and graphical format.
Harmonics display the amplitude and phase of each harmonic to the 63rd harmonic in both graphical and textual format.
Phasor diagram
Flicker
Event
The phasor screen displays a graph that indicates phase relations between voltage and current based upon the angles at the fundamental frequency, as determined by Fourier analysis. Phasor diagram displays voltage and current phasors for all channels. Functioning as a phase angle meter, the unit can display system imbalance conditions and provides such information in textual form also. The phase angle display can also verify if monitoring connections have been made correctly. Animated phasor demo rotations demonstrating resistive, inductive and capacitive loads can be displayed.
Flicker is a phenomenon due primarily to rapid small fluctuations of the voltage. Loads that exhibit continuous, rapid variations in the load current, particularly the reactive component, can cause voltage variations often referred to as flicker. Flicker is characterized by modulation at a frequency typically less than 25 Hz. Modulating signal magnitudes as low as 0.5% of the fundamental for frequencies between 5-10 Hz can result in perceptible light flicker.
An event occurs when a programmed threshold limit is crossed. An event consists of the pre-trigger cycle(s), trigger cycle(s), and post-trigger cycle(s).

Monitoring capacity
Automatic setup, Wizard setup, or Advanced setup
Tre nd
The 4400 can monitor the following power configurations:
• Single Phase • 3 Phase 2-Watt Meter Delta
• Split Phase • Generic
• 3 Phase Delta • 2 1/2 Element without V
• 3 Phase Wye • 2 1/2 Element without V
B
C
While monitoring any of the above configurations, the 4400 can also be connected to monitor neutral to ground voltage and neutral or ground current.
Setup is a configuration of parameter thresholds that control the data recorded by the
4400. Users may perform instrument setup in three ways: via Automatic Setup which utilizes auto-configured settings and allows users to proceed directly with data monitoring; via Wizard Setup which follows a step-by-step sequence where users go through a series of circuit setup screens; or via Advanced setup which allows users to modify trigger parameters and intervals or tweak threshold settings under the Advanced Options.
Users can generate plots for all journalled data combined with min/max recordings of that parameter. Most journal parameters have multiple channels to plot.
Reports
Data Card
Users have two options on how to view QOS compliance reports.
EN50160 displays statistical reports on QOS compliance based on an analysis of the voltage as per requirements of the EN50160 standard. Compliance data is presented in bar charts, statistical tables, and graphs. Statistical data is calculated on the required parameters specified in EN50160 over one week interval to produce a PASS/FAIL decision of QOS compliance.
Status presents a report summary for Standard PQ, EN50160, and Motor Quality parameters via the annunciator panel. The panel is color coded such that green indicates the parameter is within limits, yellow means it is moderately out of limits, red signifies it is severely out of limits. Unlike the EN50160 which reports on QOS compliance on a weekly basis, Status monitors compliance continuously. There is also the option to view a parameter in more detail i.e. display its data plot, threshold values, or edit parameter/channel settings.
4400 supports the use of Compact Flash data cards with AT LEAST 32MB storage capacity. The user replaceable data card is used as primary storage for data. Data monitoring CANNOT proceed without the data card. The 4400 is designed to accommodate the Compact Flash card in its native format, and does not require the use of a PC card adapter. However, a PC card adapter can be used to read the data into a laptop or other computer with a PC card slot.

Harmonics
Harmonics display
The 4400 allows users to view voltage and current harmonics/interharmonics in graphical or in list form. Harmonics are waveform distortion, a steady-state deviation from an ideal power frequency sinusoid and is characterized by the spectral content of the waveform. Interharmonics are frequency components between the harmonic frequencies. The IEC 61000-4-7 Standard dictates that harmonic analysis is done using a synchronous window of 10 cycles for 50 Hz, or 12 cycles for 60 Hz. This results in bins which are nominally 5 Hz wide. The actual width of the bins is equal to the actual frequency divided by 10 if the nominal frequency is 50 Hz, and 12 if 60 Hz. For example, if actually operating at 49.9 Hz, the bin is 4.99 Hz, but is labelled “5 Hz” as specified by the standard.
Use the respective touch screen buttons to display the next Channel (Channels A, B, C, D) and the next Parameter (V, I, W) of harmonic data. The number of harmonics/ interharmonics displayed is up to the 60th. Summary values of odd, even and total distortion are displayed. A summary of harmonic distortion as well as interharmonic distortion values per phase/parameter are also available on display.
Users can determine the number or range of harmonic frequencies to trend and view in detail. There is also the option to select how to plot harmonic/interharmonic data and specify the units of measure by which harmonic data is calculated.
Harmonic Graph Users can choose the unit of measure by which harmonic data is calculated and graphed, based on a Percentage of the fundamental value or in Engineering units (volts and amps). Frequency components of harmonic graphs can be displayed either in Hertz or in Harmonic Number. The graphs can be zoomed and rescaled.
: Harmonics are measured in accordance with IEC 61000-4-7 Class 1.
Harmonic List measured values: frequency and harmonic number; magnitude in Engineering units and percent of fundamental; phase in degrees (for harmonics only). This list is displayed in order of ascending frequency, and can also be sorted in order of descending magnitude.

*The odd contribution is the square root of the sum of the squares of the relative amplitudes of harmonics 3, 5, and 7 through N-1, where N is a function of sampling frequency. The even contribution is similar for harmonics 2, 4, and 6 through N. Total value is the square root of the sum of the squares of the odd and even distortions.

Harmonic/ Interharmonic data plots
The voltage and current harmonics and/or interharmonics for each phase channel can be trended using the Options button. The properties specified under Harmonic Options apply when harmonic/interharmonic data is viewed in either graph or list form.
Properties under Show Harmonics... pertain to both the graph and the list, and determine how the harmonics and interharmonics are used.
If Show Harmonics... only is enabled, then only the actual harmonics are shown.
If Show Harmonics... and Interharmonics is enabled, the spectrum will include all the (nominal) 5 Hz bins, which includes the actual interharmonics as well. On the graph, the harmonics are shown in the channel color, while interharmonics are shown in gray color. On the text, the harmonics are shown in boldface.
If Show Harmonics... calculated including adjacent interharmonics is enabled, the interharmonics are not explicitly shown but the harmonic values include the adjacent interharmonic values in their calculation, as specified by IEC 61000-4-7.
The IEC 61000-4-7 Standard specifies that the interharmonic bins adjacent to the harmonic be included in the computation of that harmonic. For example, if there was a 3rd harmonic (150 Hz) of 10%, and the value of the 145 Hz bin was 1%, and the value of the 155 Hz bin was 2%, then the value reported in the bin labelled “150 Hz” would also include contributions from the 145 Hz and 155 Hz bins. This would give

Wizard Setup
Introduction
Monitoring modes
Wizard Setup guides the user through the circuit setup step-by-step, via a series of screens prompting for information about the circuit to be monitored. The unit automatically turns on the correct channels, sets the parameter thresholds and waveform capture settings depending on the detected circuit type, nominal voltage and current values, and monitoring mode specified by the user.
The 4400 allows users to monitor events in the following setup categories: Standard Power Quality, Current Inrush, Fault Recorder, Long-term Timed Recording, Continuous Data Logging, and EN50160 Power Quality mode. Selecting any setup category automatically sets trigger and capture conditions. Advanced users are free to mix and match settings (see Chapter 6 Advanced Setup Options).
Standard Power Quality, Demand, Energy existing rms and waveform conditions to optimize setups to reliably capture data. This feature ensures that the first-time user gets the expected results, while providing the experienced user with the ability to tweak settings for specific applications. Either way, the necessary data used to identify critical events and optimize mitigation solutions is recorded into the data card as it occurs.
Current Inrush such as impedance changes during motor energization or the I is key to preventative maintenance and enhanced power system performance. Inrush­type events such as motor start-up typically requires extended duration cycle-by-cycle recording. With 4400, users can capture and store detailed data to evaluate system performance against specifications and previous benchmark data. Under the current inrush mode, triggers are current-based. By operating in the inrush mode, the instrument will capture and store highly detailed data to a Compact Flash data card in real time, then rearm and be ready to capture data during the next test run.

Long-term Timed Recording, Demand, Energy
: Performing a statistically valid power quality energy survey requires the capture of a set of basic data over an extended period of time. The 4400 is designed to facilitate long-term monitoring by collecting min/max/ avg data at each pre-determined interval in order to perform post-process harmonic and other events analysis. It is also designed to be left unattended in the field, recording statistically representative data for long-term analysis. Using the Dranetz

Scale Factor Setup
Scale Factor Setup
What is a scale factor?
When to use
Non-Dranetz equipment
Sample calculation
A scale factor is the ratio of the input to output for a particular current transformer (CT) or potential transformer (PT). A scale factor is entered in the 4400 and then multiplied automatically by the measured voltage or current so the unit displays the correct values, as referenced to the primary side, rather than the secondary side of the PT or CT.
NOTE: If voltage and current connections are made without using any of the above named devices, the scale factor should be set to 1.
Scale factors must be entered for the following conditions:
• A Dranetz
• The current connections are made using a Dranetz
• The voltage connections are made using a PT.
Refer to the CT name plate or to the manufacturer’s literature to determine the scale factor.
The scale factor for a single CT or PT is calculated from its step-up or step-down ratio.
Example of step-down ratio If a current transformer has a step-down ratio of 1000A:5A, therefore:
current probe is connected to a permanently installed CT.
ISO box.
Scale Factor = 1000/5 = 200
Example of step-up ratio If a potential transformer has a step-up ratio of 1V:10V, therefore:
Scale Factor = 1/10 = 0.1

Frequency synchronization
Frequency Tracking
Normal frequency synchronization (sync) of the 4400 analog signal processing circuits is controlled by analyzing the external AC voltage signal input on channel A. Loss of external sync causes the 4400 to poll other valid voltage channels (A, B, or C) for an alternate external sync. If none exists, then internal sync is automatically selected. The frequency used for internal is entered under Frequency on the Nominal Values screen (see page 5-14).
Depending on the type of circuit configuration, the instrument will attempt to autosearch to sync to any valid voltage channel. The autosearch function will be disabled when users specify sync mode Ch D Volts. Typically, external sync on Ch D is specified if it is known that signals on A, B or C are inappropriate for use as a sync source (i.e. the frequency is unstable or DC). A low distortion 50, 60 or 400 Hz signal can be input to Ch D and used as a sync signal.
NOTE: Failure to connect an external sync or to select an internal sync during current monitoring will result in erroneous data being collected and displayed.
Tracking determines how the phase locked loop circuitry responds to sudden changes in frequency.
Standard mode
: On a normal power quality application [Standard], the system is designed to “ride through” voltage changes to keep tracking the fundamental frequency even in the absence of voltage.
Fast mode
: When operating on a local generator [Fast], the frequency will vary more as loading changes occur. The Fast mode allows the instrument to follow these changes more closely.
Internal mode
: In cases where no reference signal is available (such as DC monitoring),
the Internal setting is used to set the sample rate.
