Hermetic Electric Machine Insulation Compatibility

When machines fail and go through the repair process it is important to understand the application. While most are fairly common and insulation upgrades from class B or F to class H are the industry norm, the compatibility with the environment can be an issue. For hermetic systems, such as hermetic compressors, insulation system compatibility […]

Capacitance Monitoring for Global VPI

There are several ways of determining penetration of epoxy resins through the global VPI cycle.  One of the ways is to perform the complete cycle and include ‘sacrificial coils’ held in a faugh-slot, then cut the coil into sections to ensure full penetration.  The next is to perform capacitance measurements during the VPI cycle and […]
