The Benefits of Aggreko Loadtesting Services
Rental equipment is available at short
notice and can be delivered and installed
in the shortest possible time-frame to meet
your needs.
The Solution to
Test Your Power Supply
Renting loadtesting equipment from
Aggreko makes sound financial sense.
Thoroughly testing power systems before
they are commissioned reduces the risk of
contract penalties due to delays.
Aggreko is the world’s leading provider of rental power solutions.
Our dedicated fleet of power equipment is supported by over
6000 employees operating from over 190 locations offering 24/7
availability and service support.
At Aggreko we understand the importance of thoroughly testing power
supply systems. We have the skills and knowledge to support your
loadtesting projects, providing you with a turn-key service including
engineering, commissioning and operational support. Our loadbank rental
services are the most effective solution for immediate requirements.
Aggreko offers a full range of AC loadbanks from 100 kW ‘resistive only’ to
6000 kVA combined ‘resistive and reactive’ in single or multiple units. Also
available are DC loadbanks capable of accepting voltages up to 240 V.
Aggreko has vast experience in finding the correct loadtest solution for any
requirement. Varying from a single 10 kW low voltage test to large multiMW high voltage applications, Aggreko’s extensive equipment range also
includes a selection of multi-tap transformers which are fitted with high
voltage switchgear and protection as standard.
What do you need to test?
• Turbine generators
• Diesel generators
• Motors (starting simulation)
• FPSO power systems
• DC generators and power supplies
• Frequency convertors
• Electrical distribution panels and
systems
• Uninterrupted Power Systems (UPS)
• Battery discharge
• Rectifiers
• Chillers
• Data Center Power and Thermal
Systems
• Air-Conditioning Systems
Aggreko takes the worry out of loadtesting.
All aspects of the project, including design
and operation, are handled by our team
of dedicated specialists. In addition, we
provide full loadtest documentation for
quality auditing purposes including method
statements and schematics.
Renting loadtesting equipment eliminates
the need for capital expenditure when
purchasing equipment. It incurs
no large downpayments or interest costs
and preserves your borrowing capacity,
thus improving cash flow.
With Aggreko rental solutions, all risks of
equipment ownership, including servicing
and repairs, lie with us.
Aggreko Equipment
Ancillary Testing Equipment
All AC loadbanks can be used in conjunction with the
complete fleet of Aggreko step-down transformers
which range from 1250 to 6300 kVA. Typically these
can operate at any voltage between 0.6 to 25 kV.
Loadbanks
Resistive-Only Loadbanks
Aggreko’s resistive-only fleet consists of 100 and 1266
kW single units, which can also be paralleled together to
provide large load capacities. Each loadbank is designed
to operate at unity (1.0pf) power factor, 400 to 440 V at 50
and 60 Hz.
The Intelligent Hand-held Terminal (IHT) provides you
with full instrumentation (volts, amps, hertz, kilowatts
and power factor) and the ability to control the loadbank
in 1 kW incremental load steps. All instrumentation
measurements are made using three highly accurate
voltage and current transformers located within the
loadbank and the print-out facility allows data to be
recorded.
These loadbanks are built to a very high industrial
standard and are skid-mounted with forklift pockets for
ease of handling.
FEATURES
• Data acquisition (volts and hertz transient graphs)
• Variable power factor control
• Automatic loadtest program capability
• Three-phase instrumentation
• Low voltage and high voltage testing
• Remote control (up to 3 km)
Resistive & Reactive Loadbanks
Aggreko’s combined resistive and inductive fleet consists
of 625, 1250, 1875, 2500, 3300 and 6000 kVA single
units, which can also be paralleled together to provide any
large load capacity. Each loadbank is designed to operate
at variable power factor and from 400 to 480 kV at 50 and
60 Hz. These loadbanks are housed in standard ISO 10
and 20 foot containers.
The uniformed control system provides consistency
and familiarity throughout Aggreko’s AC loadbanks and
combined with the additional feature of multi-language
display, offers the customer a complete user-friendly
method of operation. The print-out facility allows data to
be recorded.
Direct Current (DC) Loadbanks
Aggreko’s DC loadbank fleet consists of various voltage
and current-rated units. Typically these can operate
between 24 – 240 volts and up to 600 amperes as single
units. Certain units can be connected together with up to
two other identical loadbanks to increase the total loading
capacity. The ammeter on the master loadbank will display
the total current of all three loadbanks.
These loadbanks are controllable in 1 ampere load steps
via a ‘dial type’ controller. Their compact design enables
the units to be sited near to the point of test, negating the
need for long, hazardous cable runs.
Transformers
To complement our fleet of generators and loadbanks,
Aggreko has a large fleet of transformers for either
stepping voltage up or down, depending on the
application. Aggreko transformers in most cases are
containerised and are supplied complete with over
current and short circuit protection on the HV breaker.
Sigma II Instrumentation System
MV/HV Monitor
The Sigma Instrumentation System (SIS) is designed
for monitoring three-phase electrical supplies, primarily
during load proving trials. Based on the Sigma Control,
SIS provides a means of directly measuring the actual MV/
HV electrical parameters, including power, voltage, current
and frequency. ‘Daisy-chaining’ the SIS into the loadbank
group using the standard Sigma plug socket connections
automatically reverts the instrumentation displayed on the
Sigma PC system from the internal loadbank LV readings
to the external inputs into the SIS. The normal loadtest
functions within the Sigma PC software package are
maintained to ensure comprehensive testing.
Internally, the unit contains a Sigma Control System module
plus voltage transformers, with switched input voltage
selection. Individual sockets are provided for voltage and
current inputs. Two current inputs are provided - 1 x 1A and
1 x 5A for connection to external CT’s.

High and Low Voltage
Data Capture Capability
The Aggreko PC system can be used as an alternative to the
Intelligent Hand-held Terminal (IHT) on any Aggreko (AC) loadbank.
The PC system provides enhanced load control along with
transient speed instrumentation, real-time graph display and full
data acquisition and reporting.
