While capable of delivering 900 A continuously and 5,000 A for short periods, the new Ingvar primary current injection test set from Megger is readily portable, making it ideal for on-site use, even in applications such as underground substations where access would be difficult or impossible for larger test sets.
The design has also been optimised to minimise inrush current, thereby making Ingvar suitable for use on supply systems with limited capacity.
Ingvar consists of a power module and a separate control module. The modules are housed in robust carrying cases, each of which weighs only around 20 kg. In addition to enhancing portability, this two-module arrangement also has the benefit of allowing the power module to be positioned close to the equipment under test, thereby reducing the length of test leads needed, while the control module is positioned for ease of access.
