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.
The PME-500-TR break timer has a built-in battery that 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.
