PowerVisa description

PowerVisa firmware

The Dranetz-BMI PowerVisaTM is a portable, hand-held, eight-channel power 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 PowerVisa 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 PowerVisa, 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 PowerVisa 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 PowerVisa firmware program card in the appropriate slot of the mainframe. See page 1-10 for instructions on how to upgrade the PowerVisa

firmware from a data card.

The PowerVisa firmware can monitor power quality phenomena for troubleshooting and/or compliance purposes. It can 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-BMI software applications such as NodeLink® and DranView®.

Touch screen function

Scope mode

Meter mode

Harmonics

All PowerVisa 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

Trend

The PowerVisa 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 PowerVisa 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 PowerVisa. 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, while 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.

PowerVisa 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 PowerVisa 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.

Basic Operation

Introduction

Battery pack

The normal power source for the PowerVisa is its internal battery pack. The AC Adapter/Battery Charger is used to charge the battery. Always charge the battery fully before use. The PowerVisa will always operate on the charger and is designed to do so, regardless of the state of charge of the battery.

Type: Sealed, rechargeable NiMH (Nickel Metal Hydride) cells.

Length of operation: The PowerVisa can operate on a fully charged battery pack for more than two (2) hours with the backlight on. When the backlight is turned off, the unit can operate for more than three (3) hours. For information on how to turn backlight on or off, see Chapter 4 Instrument Settings - Set Display Preferences on page 4-6.

Charging: The battery pack can be charged by connecting the AC Adapter/Battery Charger to the PowerVisa. A screen warning will appear during operation when battery charge is low. A depleted battery pack can be recharged in six (6) hours whether the unit is on or off. The Battery Charge Indicator glows steadily while charging, and flashes when fully charged.

NOTE: The Battery Charge Indicator functions whenever the AC Adapter/Battery Charger is properly connected.

AC power source

The PowerVisa can be operated from a 50/60 Hz 120/230V AC power source with or without the battery pack installed.

Connect the AC Adapter output cable to the Input Connector on the right side of the PowerVisa. Connect the AC Adapter power cord to an appropriate outlet.

Refer to Appendix C for the specifications and replacement of the batteries contained in PowerVisa.
