For all their energy savings and control benefits, when VFDs fail, they bring motor-driven industrial operations to a dead stop. To avoid such situations, savvy engineers ensure drive-system ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

Targeting ac-motor-drive applications, the symmetrical VFD (varying-frequency-drive) cables carry power from industrial ac-drive systems to ac motors. A dual-copper-tape shielding provides a ...

The right shielding for substation wire and cable continues to be a critical factor in enabling substations to become smarter, more sophisticated and more reliable. New sensors, distributed computing, ...

Although cable of all types tends to be overshadowed by other, more “glamorous”, technologies, they are nevertheless essential elements in just about any security system. One of cable’s most important ...

Testing most products for radiated emissions usually requires all I/O and power cables to be attached to the equipment under test (EUT) and spread out in accordance with the specific product standard.

VFD cable from AutomationDirect is now available in customer specified lengths in one-foot increments. VFD cable from AutomationDirect is now available in customer specified lengths in one-foot ...

Although the 2005 Code-change cycle often included lively debate on the use of non-shielded cables at 4.16kV and 2.4kV, in the end, the majority of the members of Code-Making Panel 6 (CMP-6) voted to ...
