Megger 560060 - Motor & Phase Rotation Tester

The Megger 560060 Motor and Phase Rotation Tester permits the electrical contractor or industrial maintenance electrician to permanently connect and tape the terminals of the motor being installed, without having to first energize the motor by a temporary hookup from a power source, if available, to determine motor rotation. Therefore, the test set eliminates the need for temporary connections that can be time consuming, costly and quite hazardous, particularly where many large, high-voltage motors are involved. Also, certain types of drives should never be rotated in the wrong direction. In such cases, the temporary hookup or trial method, having a fifty-fifty chance of being wrong, can do serious harm.

Features:

• Complete phase-sequence and motor rotation testing in one instrument
• Ensures correct phase hookup in one easy test
• Rugged and portable tester
• Performs additional polarity and continuity checks
• Determines rotation direction of one-, two- or three-phase motors before connection to line
• Determines phase rotation or sequence of energized power circuits
• Determines polarity of instrument and power transformers
• Determines phase/polarity of unmarked motor windings
• Identifies true phase sequence of energized ac power lines up to 600 volts (Higher voltages can be tested by interposing a step-down transformer.)
