Electrical measurement devices for a device under test

An electrical measurement system comprising:

• a first electrical measurement device comprising a first conductive cable having a first plurality of conductive filaments on a first end and a first electrical connector on a second end, the first plurality of conductive filaments being held in contact with a first portion of a rotating element of a device under test during a measurement operation via a first cable mount;
• and
• a second electrical measurement device comprising a second conductive cable having a second plurality of conductive filaments on a first end and a second electrical connector on a second end, the second plurality of conductive filaments being held in contact with a second portion of the rotating element of the device under test during a measurement operation via a second cable mount.
