Transformer testers - winding resistance testers - Miller Instruments 221
Make Miller Instruments
Model 221
Description Digital Milliometer
The model 221 digital milliohmmeter is designed for rapid and accurate measurement of low resistance values ranging from OHMS down to microhms. The instrument is particularly effective in measuring the resistance in large transformers which, because of their high inductance, tend to have a long settling time. The instrument has a built in circuit for detecting open circuits as short as one milliseconds; a useful feature for detecting faulty tap changers. The model 221 is equipped with an elaborate surge suppresser to absorb the transients associated with transformer testing.
