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
