MEGGER MTR105 Rotating Machine Tester

The MTR105 is a dedicated Static Motor Tester with Megger’s tried and trusted suite of insulation resistance tests (IR), plus all the great traditional features and reliability of Megger’s testers.

The MTR105 takes the test abilities of Megger’s proven IR test instruments adding DLRO four wire Kelvin low resistance test, inductance and capacitance tests to provide a versatile motor tester, all packaged in a robust handheld instrument, which up to now has simply not been available.

Additionally, the MTR105 incorporates temperature measurement and compensation (for IR tests), motor direction of rotation plus supply phase rotation tests.

These new test abilities make the MTR105 a real world, versatile, handheld motor test instrument. The MTR105 comes in an over-molded case, providing increased protection and robustness, achieving an IP54 weatherproof rating.

Applications
Production tests for new manufactured motors and generators.
Test repaired and refurbished motors and generators.
Monitoring and maintenance of in-service motors (off-line) in the field.

Typical Industries Include:
Utilities: Electrical power generation, water, oil / gas.
Industrial: Production line / factory maintenance teams, HVAC field engineers.
OEM: Motors / generators.
Service: Motor repair workshops.
Transportation: Rail, electric vehicles, marine, etc.

Safety
The MTR105 is designed to be exceptionally safe to use. The fast detecting circuitry reduces the likelihood of damage to the instrument if accidentally connected to live circuits or across phases.
Meets the international requirements of IEC61010 and IEC61557.
Live circuit detection and test inhibit on all measurements with user notification (except for direction of rotation measurements).
User selectable insulation test terminal lockout voltage 25 V, 30 V, 50 V, 75 V (default is 50 V).
Detection and inhibit functions when the protection fuse has failed.
Suitable for use on CAT III applications and supply voltages to 600 V.
