APPLICATION OF STANDARD TESTING METHODS IN THE MAINTENANCE OF THREE-PHASE ASYNCHRONOUS MOTORS

U završnom radu su opisani standardni kvarovi koji se mogu pojaviti na trofaznim asinkronim motorima, te je glavni dio rada usmjeren na standardne metode ispitivanja koje se obavljaju na spomenutim motorima. Primjena standardnih metoda ispitivanja trofaznih asinkronih motora uvelike pomaže kontroli te pravovremenom reagiranju na moguće kvarove koji se mogu pojaviti na spomenutim motorima. U radu je spomenuto 14 dijagnostičkih metoda, no važno je napomenuti da to nisu sve moguće metode te da ih je još puno našlo primjenu u dijagnosticiranju kvarova motora. Metode se razlikuju u mnogo aspekata, ali najvažnija razlika između svih je razina jednostavnosti izvođenja te dobivena točnost.This final thesis describes standard malfunctions that may appear with a three-phase asynchronous motor and the main part of the thesis is directed to the standard methods of testing which can be performed on said motors. The use of the standard methods in three-phase asynchronous motor testing helps greatly in control and in timely response to possible malfunctions that may appear on said motors. This thesis mentions fourteen diagnostic methods, but it is important to note that not all diagnostic methods are mentioned and that many of them may find their use in diagnosing motor malfunctions. Methods differ in multiple aspects, but the most important difference is the level of simplicity of execution and accuracy
