With the critical role that protective relays play in arresting and isolating electrical faults, it is extremely important to know that they are operating in concert with their design and intent. The unplanned downtime and damages associated with the mis-operation of protective devices during fault conditions can be incredibly detrimental. Regular maintenance testing allows the discovery and resolution of such issues before they are able to escalate into very costly problems.READ MORE >>

The Fault Wizard from Innovative Utility Products is a versatile and portable fault locator that uses arc reflection technology. It helps to localize faults in direct buried cables and display the distance to the faulted portion of the cabling. It also has other features that help make troubleshooting underground cable fast and easy.READ MORE >>
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.READ MORE >>
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.READ MORE >>

Capacitance and Dissipation Factor (C&DF) test equipment can sometimes be limited by their power supply when testing highly capacitive objects. An example of power system apparatus that might fall into this category would include large motors, generators or cabling. Test specimens that have a characteristically higher capacitance value will sometimes achieve a maximum output current from the test equipment at less than the desired test voltage. By appropriately positioning a resonating inductor that is adjusted to resonate with the capacitance of the test object, the range of charging current from the test equipment can effectively be extended to accommodate testing of more capacitive test objects.READ MORE >>
The magnetically supported Iris Power RIV800 Robotic Camera Inspection Vehicle has been developed to provide an automated scanning method for the ELCID stator core interlaminar insulation test equipment.
The Vehicle allows scanning of the stator core of a generator or large motor, in order to test the integrity of the stator lamination insulation more efficiently. The equipment can also be adapted to carry other lightweight attachments for stator inspection including the mini-camera or wedge tightness probe. A single control unit is used to provide power and control to the vehicle and camera module.READ MORE >>
Engineers prefer to test electric cables using very low frequency or VLF Hipot testing because of its safety and simplicity. This diagnostic test checks if the cable is still capable of withstanding the electricity passing through it. A test voltage of slightly higher than the cable's rating is applied and held for a specified time depending on the purpose for which the test is being performed. If the cable is bad, the defects in the cable will further deteriorate to the point of failure.READ MORE >>

When stator wedges are loose, this allows stator coils or bars to vibrate in the slot, leading to insulation abrasion and eventually a ground fault. Stator wedges are traditionally tested for tightness by tapping them with a hammer and listening to the sound produced. This method is slow and prone to inconsistency. Electronic evaluation of wedge tightness is faster, more accurate and provides more consistent results.READ MORE >>
