Telephone Test Sets
-
Telephone test sets are a standard among telephone linemen. For the past 100 years, a test set’s functionality hasn’t changed much. Times are changing, networks are changing and now butt sets are changing. No longer are they single-purpose tools but are evolving into full-fledged, multi-functional test sets. Enter Fluke Networks’ newest line of VDV (voice, data and video) telephone test sets. We’ve taken the best features from our existing line, added new technology and totally redesigned them to lighten up your tool belt.

Air Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
