Marposs’s new LT400 test system is designed to perform partial discharge measurements on coils, motors and generators. With the LT400, companies can perform standard high-voltage tests with partial discharge measurements, allowing the discovery of defects not detectable with the standard tests.
The LT400 integrates numerous tests, including EN60270 High-Voltage Tests, EN60034-18-41 Pulse Partial Discharge Tests, partial discharge inception voltage tests, surge tests with partial discharge, insulation resistance tests, and dielectric strength tests.
The company says its EDC partial discharge technology, which is based on capacitor coupling technology, is less sensitive to external noise and more suitable for production applications. The system uses the same software as end-of-line testing, making it easier to correlate the laboratory results with those from production.
