The ARGIS air gap inspection can be performed in approximately 3.5 shifts, depending on the size and accessibility of the generator. If required, multiple teams can be sent to reduce inspection time.
The ARGIS robot is equipped with several measurement devices. Several measurements can be performed in one run.
The “air gap” is defined as the space between rotor and stator. However, the geometry of the retaining rings also determines whether the ARGIS robot will fit. The “entrance” gap is defined as the space between retaining ring and stator inner surface. The robot will fit if the entrance gap is 17 mm or larger. If the entrance gap is less than 17 mm, the ARGIS robot may fit, depending on the geometry of the step irons and the retaining rings.
