PowerPro with PowerFlow Firmware

Introduction

The PowerPro represents leading edge technology in the

measurement of Power Quality. From the logger front panel or, for

more detail, using Candura Instrument’s PowerView software you can

view:

• Trends in Voltage, Current, Power and Frequency

• Waveforms and harmonic activity for both voltage and current

• Voltage sags and swells

• Frequency deviations

• Flicker (IEC 868 / IEC 61000-4-15) - Optional

The PowerPro is an 8 channel power quality data logger. It

can monitor 3 phases of voltage and current as well as a neutral

voltage and current. Measured parameters are updated every ½ cycle

to ensure that nothing is missed. Most measurements can be viewed

on the front panel LCD in the field and logged data can be transferred

to a computer using the removable memory card. The memory card

interface also provides the means to program the logger and to

upgrade the PowerPro firmware. The logger is powered from the V1

voltage measurement input, or if V1 is a weak source an auxiliary

power supply may be used. The PowerPro has an internal battery

that can power the logger for up to 8 hours in the event of a power

outage. Voltage inputs are transformer isolated and protected with

metal oxide varistors and fuses for safety. The entire unit is enclosed

in a rugged water tight case for use in harsh environments.

Safety

Although this instrument is designed to be as safe as possible, safety

is ultimately the responsibility of the operator. This instrument should

only be operated by suitably qualified and authorized personnel.

Please read and UNDERSTAND the following information before

operating this instrument

• The PowerPro uses a membrane keypad that could be damaged

if a sharp object is brought into contact with it. This may expose

the operator to potentially hazardous voltages.

• Frequently inspect the test leads and the instrument for damage.

If the instrument shows any signs of physical damage or functions

improperly, it should not be used.

• Never work alone with high voltage circuits. Ensure that a

qualified observer is mindful of your activities.

• When performing any measurements involving high voltage

circuits, all connections should be made to the circuits while the

power is off. To ensure personal safety, the test leads and related

connectors should not be handled while the circuit is energized.

• Do not attempt to measure any voltage higher than the maximum

rating of 750V RMS. Failure to observe the maximum rating could

result in damage to the equipment or personal injury.

• Refer servicing of this instrument to qualified personnel only.

Potentially lethal voltages may be present inside the case. If any

of the protective circuitry is improperly repaired, the safety of this

product could be compromised.

PowerPro with PowerFlow Firmware

Quick Start

Connecting the PowerPro to the circuit to be measured is a

straightforward process.

1. Connect the voltage leads for each phase to be measured. For

proper operation V1 must always be used. Three phase circuits

can be connected in either a ‘wye’ or 'delta’ configuration. Refer to

the ‘Hookup Configurations’ section for the various methods of

connecting the voltage leads.

2. Connect the phase CT clamps or the three phase Flex CT.

Note that only one or the other may be used – if the three phase

Flex CT is used then the phase CT clamps must be disconnected.

The neutral CT clamp may be used at the same time as the three

phase Flex CT.

3. Ensure a memory card is installed.

4. Turn the logger on (if it is turned off) by pressing and holding any

key except F6. If installed memory card has data, select 'NO'

when asked to load Setup and Data from card.

5. Use the ‘SETUP’ key and function keys to check and modify any of

the setup parameters. If a computer is connected to the serial

port, run PowerView software and select 'Logger' and 'Configure'

to check and modify any of the setup parameters.

6. Press the ‘Record’ key and then F2 to start recording. If there are

any error messages, please refer to the ‘Hookup Diagnostic

Warnings’ section.

7. The measured values can be viewed from the logger using

'DISPLAY' key and function keys. If a computer is connected to

the serial port run the PowerView software and select 'Logger' and

'Status'.

8. To stop logging press the ‘RECORD’ key and then F4 followed by

F1 to confirm the stop command.

Note: Static discharges may occur when connecting leads,

communication cable or memory card, depending on

environmental conditions. This is not hazardous and will not

damage the logger. However it may affect the integrity of the data

if the logger is recording. Connection and disconnection of leads

etc. should be done while the logger is not recording. Before

handling a logger that is recording the operator should discharge

any potential static by touching a grounded object.

9. Data is transferred to a computer using the memory card. When

logging has been stopped the memory card can be removed from

the logger. The memory card can be inserted directly into an

ImageMate Card reader or, with a PCMCIA adapter, it can be

inserted into a PCMCIA slot in a laptop computer. Run

PowerView and select 'File', 'Open' and then go to the drive that

has been configured for the memory card, it will have the

description 'Power Pro'. Change the file type to 'Data Card Files'.

If there is data on the card you will then see a file that can be

opened. After opening the file a directory and file name (you can

keep the same file name) must be selected for the processed file.

distribution systems. Following are descriptions of the five most

common field setups:
