Test Transformers Easily with the M5400 SFRA from Doble Test Equipment

POSTED BY Protec Tech Team

When transformers experience physical impacts or sudden changes in the electrical system that cause movement of the physical components, it is helpful to know if these events have had permanent impacts on the internal geometry of the transformer.  This can be particularly difficult in liquid filled transformers without going through the time and very costly expense of de-tanking the transformer.  However, the application of Sweep Frequency Response Analysis, allows for a highly sensitive measurement to physical changes of the internal workings of the transformer without having to without having to visually inspect the inner workings of the transformer.

Rent the Cooper VFI Vacuum Fault Interrupter Tester

POSTED BY Protec Tech Team

The Cooper VFI Vacuum Fault Interrupter Tester is a current injection device designed to simulate Fault Current for verification of minimum trip values and time current characteristics of Tri-Phase and TPG electronic control boards utilized in VFI pad-mounted switchgear.

Three internal flux-shift trippers enable confirmation of the presence of sufficient levels of energy upon the control board for operation of pad-mounted VFI flux-shift trippers. The on-board flux-shift trippers also enable self-checking of the VFI tester prior to general control testing. Further flux-shift tripper capability enables verification of operation of the flux-shift trippers within the VFI unit under test, external to the Cooper VFI tester.

HV Diagnostics EZ-Cable ID Now Part of Protec's Rental Inventory

POSTED BY Protec Tech Team

The HV Diagnostics EZ-Cable ID Test Instrument allows electrical testing personnel to accurately and effectively identify either one or three cables or cores anywhere along the length of the cable in one identification process. This can be done on both single phase and three phase networks. In addition to identifying the correct cable and phase, the resultant current and frequency in a cable can also be measured by the instrument.

The test set consists of 3 main items: A receive (Rx), transmitter (Tx), and inductive clamp/s, all housed in a rugged, injection molded carrying case. The instrument is extremely easy to use and can be powered by either the internal battery, AC mains or from an auxiliary 12V DC supply. The receiver has a backlit LCD display, is battery operated, housed in a rugged, rubber holster and has a flexible pickup coil to easily wrap around cables.
