PDTech Dielectric Response Analyzer (DRA-3)
The DRA-3 measures the charging and discharging currents of insulation (also called polarization and depolarization currents)
- Used for off-line insulation diagnosis for generators and motors and transformers.
- Measures the charging and discharging currents of the winding of stator or rotor insulation.
- Allows you to connect all three phases and the ground at one time.
- Allows the possibility to measure all three phases together to ground, each phase separately and between the phases.
