INSTRUMENTS

Bridex Singapore Pte Ltd was founded in 1973 as a manufacturer of instruments transformer for

the Asian market. We are the first local electrical switchgear components manufacturer that

launches our own Asian identity – Rudolf.

Today we aim to become a knowledge-based, technology driven engineering organization,

with emphasis on providing solution for electrical distribution and control, in area of instruments,

distribution & protection and standard components. With our present headquarter in Singapore

and subsidiaries that are located in Philippines, China and Australia, we are well equipped to

service both local and Asia-Pacific countries.

Product Introduction

What are the reasons behind an increasing trend toward the use of power meter and power

analyzer? To replace the conventional metering using analogue meter? We take reasons better

than this. With just one product, we achieve consolidated measurement, energy metering,

alarm monitoring, possibility for remote communication, the possibility for control and command

and the possibility for data logging function via sole proprietor software. These possibilities

allow the user to obtain and manage information thereby providing the user with the capability

to control cost, improve power quality and participate in control system (BMS)

These functions can be achieved by your selection of any of RUDOLF:

Basic Features

Power Quality Analyzer - PQA144

The PQA-144 is an instrument that can be used as a Power Quality Analyzerto support any network connection configuration, such as 3 and 4 Wire, Wye and

Delta, and single-phase. The connection is either direct (up to 347/600 VAC) or

using a Potential Transformer (PT). Minimum burden on the Current Transformers

(CTs) is achieved by connecting the CTs without a physical contact. Delta networks

use 2 or 3 CT’s and Wye networks use 3 or 4 CT’s.

When the system is configured as a Delta network, it displays the L-to-L current and

power, in additional to the line currents and total power. The system measures the

line current from the CTs and calculates the current and power inside the feeder

transformer (or generator). In completely balanced networks, the internal currents

are 1/√3 of the line currents. In many cases, the network is not balanced and the

internal currents are different from these expected.

The unique dual load model is advantageous when monitoring two loads (6 current channels) connected to the same feeder.

The analyzer displays each load separately, as well as their total or deduction.

Typical applications for the dual load model are:

Two Transformers

When two transformers are connected in parallel, the analyzer measures each transformer separately, add their output and

displays one joint measured network, as well as each transformer separately.

Large Loads

Loads on the transformer may include one large load (such as large motor, welder or other machines) and many relatively

small loads. In this situation it is advantagous to monitor the mains and the large load separately.

Connection of the mains to Load1 of the Power Analyzer and the large load to Load2 provides accurate measurements of the

mains, the large load and all other loads.

Typical connection of a single loadpower analyzer in a Wye network
