What we do
Loadbanks
Ensuring unmatched reliability and performance
At AVK, we understand the importance of regularly testing your power supply systems. That’s why we’re committed to providing the best loadbank services in the industry. A loadbank is a piece of electrical test equipment that simulates the normal electrical load of a power source, allowing it to be tested, calibrated, and verified under controlled conditions.
Whatever your needs, we have the skills, equipment, and experience to support. Contact us today to learn how we provide solutions to the most complex, critical, and large-scale load-testing projects, offering critical insights and long-term peace of mind.

-
Comprehensive services
We offer full turnkey solutions, designing and installing low voltage (LV) and high voltage (HV) loadbanks for a wide range of onsite testing requirements. Our services include: resistive, reactive, and capacitive testing; G1, G2, and G3 BS testing specifications; power factor testing; HV load testing, monitoring, data recording and reporting; and integrated systems tests.
-
Expert teams
Our highly skilled team includes LV/HV project engineers, who are experts in the deployment and operation of loadbanks. We conduct regular training to ensure that we stay up to date with emerging technologies.

-
Advanced equipment
Our AC loadbanks range from 40kW resistive-only systems to multi-megawatt combined resistive and reactive systems in single or multiple units. We also supply DC loadbanks and leading power-factor loadbanks capable of accepting various voltages.

-
State-of-the-art technology
We utilise Avtron loadbanks, known for their reliability and performance. The Sigma data-capture system provides detailed charts and reports that are invaluable to clients and commissioning teams.
-
High power capacity
We support testing up to 20MVA / 16MW with advanced equipment, including a fleet of 5MVA & 2.75MVA resistive-reactive loadbanks. We can also support any HV application up to 20kV. All-inclusive with H07 Titinex Double Insulated Tri Rated cable.
-
Flexible testing options
Our loadbanks can operate with both LV and HV power sources, offering versatility for different testing scenarios.
