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 >>
Time domain reflectometers are tools that can help make cable troubleshooting faster and easier. Instead of spending time and effort finding faults manually, these devices can localize the fault within seconds. These testers are especially valuable on cable installations that are several miles long. They are not only suitable for cable fault location in electrical systems but also in telecommunications, television and computer network facilities.READ MORE >>
Relays play a critical role in the protection of electrical power systems. They are used to monitor and control the operation of power system components. For example, if a protective relay were to senses a fault condition, it could tell a circuit breaker or some other protective device to open and thereby isolate the faulted portion of the circuit.READ MORE >>
