Inductance, capacitance and impedance meter
0 - 12 kV | M4100 Doble Lemke

The M4100 is the world's leading instrument for evaluating the condition of high-voltage power apparatus. It sets the standard for accuracy, reliable test results, and intelligent diagnostics for customers worldwide. The M4100 was engineered from the ground up to overcome the common problems that plague other test instruments.

The instrument evaluates the integrity of high-voltage substation apparatus by measuring the power factor/tangent delta and a number of other values. It also measures capacitance, to evaluate physical changes to the apparatus.

The M4100 allows you to perform a variety of diagnostic tests:

* Power Factor testing to confirm insulation integrity and quality
* Capacitance testing to measure physical changes that may have occurred to the apparatus
* Turns Ratio testing to detect shorted turns or winding damage
* Leakage Reactance/Short Circuit Impedance testing to evaluate winding deformation
* Single Phase Excitation Current testing to evaluate the transformer's magnetizing circuit
