Advanced Precision Milli-Ohmmeter MIKO-9A
MIKO-9A milli-ohmmeter is developed to measure DC resistance in the range 1 µOhm – 30 kOhm with test current up to 10 А for: Windings of power and measurement transformers, windings of electric motors, generators, linear compensators and windings of other high-inductance equipment; Contacts of circuit breakers, resistors, buses and other inductance-free circuit; Equalizing, current limiting and other resistors of high-voltage circuit breakers; Сables.

AUTO Mode
Special mode AUTO 3ph allows simultaneous connection to three phases of the transformer and measurement with automatic switching between phases. This mode reduces the amount of reconnecting to/from the object under test.
OLTC
OLTC in-place check mode allows the user to assess the state of the switching OLTC equipment with current limiting resistors without removing contactor tank cover (DRM – Dynamic Resistance Measurement method).
Resistance Measurement
The instrument is capable of simultaneous resistance measurement across 2 windings, which guarantees fast and accurate DC resistance measurement of power transformers with delta connected secondary windings, when conventional methods do not guarantee reliable results.
