INTRODUCTION

This manual is intended to be used as a guide in the

installation, configuration and operation of the

CVMk2

network analyzer, for optimising the system's benefits.

Read with attention and follow the warnings and

symbols.

1. INTRODUCTION

1.1 DESCRIPTION

CVMk2 measures, calculates and displays the primary electric parameters in balanced or

unbalanced three-phase industrial networks.

True RMS values are measured using three alternating voltage inputs, two voltage references

(neutral and ground), and four current inputs to measure secondaries …/1A or …/5A, coming

from the outside current transformers. It should be considered that when secondary .../1 is

selected, the calculation is made by the software.

The

CVMk2 network and power supply quality analyzer is a programmable measuring

instrument. It offers a wide variety of uses, which can be selected from the instrument's

configuration menus. Prior to using the analyzer, read the following sections carefully: power

supply, connection and configuration. Then, choose the best operating method for obtaining

the desired data.

CVMk2 permits viewing the electric parameters on a backlit 1/4 VGA graphical display. Real

time, maximum or minimum electric parameters can be viewed by pressing the corresponding

key. Internal processor shows more than 500 electric parameters via the display screen and

communication. Said parameters may be fed from a single or three phase system.

CVMk2 has the following important features:

• Outside dimensions 144x144x116 mm.

• Mounted on a DIN rail (measurement module) with display screen on panel (96x96 mm,

144x144 mm or 103 mm (4") diameter hole.

• True RMS value (TRMS) measurement.

• Class 0,2 or 0,5 in Power and Energy (*).

• Real time, maximum and minimum values for each parameter with date and time.

• 1/4 VGA graphical display.

• Possible to configure the display screen as the MASTER for 32 measurement modules.

• Multi-tariff equipment (allows to program up to 9 tariff)

• Memory of present, month and annual energy consumed and generated.

• Graphical display of wave forms and voltage and current phasors.

• 8 digit (100 GW·h) counter to track energy consumed and energy generated.

• Recording of power supply quality events on voltage.

• Expandable with inputs/outputs expansion card.

• Implemented in the

CIRCUTOR energy management software, PowerStudio Scada.
