Successful testing of MIKO-9A milli-ohmmeter

At the end of August SKB EP held an on-site demonstration of modern milli-ohmmeter MIKO-9A. It is designed for resistance measurement in inductive and non-inductive circuits. The testing was performed on а power transformer TMN-6300/110-UHL1.

MIKO-9A is one of our flagship devices. 4 measurement channels are built into this device that allow you to measure resistance on 3 windings on the HV or LV side without unnecessary cables reconnection. The DC resistance measurements were done directly on 3 phases, so the specialists didn’t have to climb up and down several times. And this measurement feature significantly reduced total diagnostics time.

Moreover, another unique feature of MIKO-9A was demonstrated during the testing. Measured transformer has an installed OLTC of SMS HM CVIII-350Y/72,5-10191W type. MIKO-9A allows switching OLTC without interrupting its diagnostics. It takes about a minute to stabilize the resistance value of the first measurement. Next measurements are displayed almost instantly.

Due to the technical features, diagnostics of an entire object with MIKO-9A milli-ohmmeter took almost twice less time than with other measuring devices of the same group.

If you have any questions on MIKO-9A or you would like to choose the devices for your equipment, please contact our specialists via phone number +7 (812) 500-25-48 or e-mail: skb@skbep.com.
