Abstract

A method of determining a dimension of an air gap in an electrical power generator for a wind turbine. The generator comprises a stator with a rotor mounted within the stator such that an air gap is defined between a radially outward rotor surface and a radially inward stator surface. The stator has a stator aperture that penetrates the stator radially from a radially outward stator surface to the radially inward stator surface. The air gap is measured by inserting an air gap measurement tool through the stator aperture so that a measurement head of the measurement tool protrudes into the air gap. The measurement tool is used to determine the radial dimension of the air gap at the respective stator aperture position. An apparatus for determining an air gap in an electrical generator, and a wind turbine comprising the apparatus is also disclosed.
