AVE mini is a more cost and space-effective solution for lower range transformers between 400 and 1200 kVA. The same electromagnetic principles as used on the standard AVE are applied. The compact design reduces the challenge in terms of available space. It is fitted with high quality single-phase transformers utilizing controller regulated variable tapping to achieve voltage balancing to a high degree of accuracy. The unit has the integrated power quality meter as optional. The operator can obtain necessary system information from the HMI panel located in the front door. AVE mini also comes in single-phase solutions, making it suitable for smaller housing areas.
Operation modes
Voltage balancing mode – Phase to ground voltage control from close to 100 percent (fault condition) to within 3 percent imbalance.
Transient protection mode – The AVE will protect electrical equipment from damaging transient overvoltages

Conventional transient protection technology
Conventional surge protection devices are too slow to react to transient overvoltages and often let through 4-5 times the nominal voltage before they react.
Applications
The AVE is designed for use in a wide range of industries. With AVE installed, all types of three-phase power systems are optimized and protected. Each power transformer requires one AVE. The AVE provides transient voltage spike protection, arcing ground fault protection, phase voltage balancing, and arc flash mitigation.
