Automatic testing device PME-500-TR

The PME-500-TR represents a breakthrough in the concept of testing, timing and condition-based analysis of medium- and high-voltage circuit breakers and combinations with disconnectors. Description Ultra-fast, error-free connections to the circuit breaker, and an intuitive, easy to learn graphical touch screen interface with multi-language menus, dramatically reduce the test time while increasing the analysis accuracy. The built-in battery supplies power for 10 hours, eliminating the need for a generator in a shut-down substation, and provides clean, pure DC current for accurate four-wire contact resistance measurement of the three main contacts in a single test. An optional plug-in module allows the integration of motion information like travel, speed, acceleration and contact sweep in the test report. Test results are immediately displayed in tabular and graphical forms, and can be directly output by the built-in thermal printer, saved in flash memory for future reutilization and downloaded later on to a personal computer for archiving and export to various data interchange formats. APPLICATIONS Open- and Close-time measurement in main and auxiliary contacts. Graphical and numerical evaluation of coil currents. Three-phase, 4-wire measurement of contact resistance. Substation’s auxiliary DC supply condition evaluation.
