The Tinsley type 5867 uses a wound component's "Q" to give an indication of the quality of the component. It is used to compare the electrical characteristics between windings, either between a known good example and a unit under test or between phases of a three phase device. Although designed for use on large motors and generators the instrument is equally suitable for use with smaller items such as industrial and domestic motors, transformers and alternators.
The instrument has internal rechargeable batteries that can be replenished using the instruments built in charger. Being simple to operate, the Tinsley 5867 is ideal for interstage testing during the manufacturing process and will easily identify shorted turns and other manufacturing defects. Its ease of use also makes the 5867 the ideal tool for service engineers to identify faults in the field.
