Detection of Loose Connections in VFD with EMPATH
With the motor and pump located elsewhere data was collected from a VFD prior to entering motor or pump information. A loose connection was detected and corrected immediately with post-confirmation.
Connecting the EMPATH Data Collector Special Applications
In this article we will not be covering safety aspects. Safety in connections is based upon corporate rules and regulatory requirements which can change while this article is available. Please ensure that you are working in a safe manner whenever dealing with electrical connections. We will cover some concepts around how connections are made in…
Energy and Environment Impact from Machine Defects with EMPATH ESA
Electrical and Mechanical Defects in an electrically driven machine have a direct impact on energy consumption. This can be from sub-standard maintenance practices, such as misalignment or belt tension, or degrading components such as bearings, belts, impellors, gears, and other parts. In this article we will discuss a simple motor/pump combination on a Variable Frequency…
Setting Up a Pump Motor In EMPATH and EmpathCMS
This is example is long so that we can demonstrate the databases built into the EMPATH Electrical Signature Analysis software.
Winding Stress Detection with Electrical Signature Analysis
Low voltage and VFD driven electric motors will often have voltage stresses between conductors. In cases where this is severe, it is detectible as discharges in the airgap of the machine. In this paper we will review one of the applications associated with turn faults stresses in stator windings of induction. The discovery was originally…
