![]() Inspect timers, power supply units, relays, and control wiring for humidity or temperature damage, as well as regular wear. For a "dead" circuit, the first thing to look for is voltage at the load point. Sure, we can see the effects of electricity, or the lack of effect in the case of a failure, but we can’t necessarily put our. Measure signals at test points between these stages and tell whether or not a stage is working properly. Location of faults on aging electrical wiring is also a key application of reflectometry in structures. Range Analyze the fault and performance information on the maintenance records of the electrical and mechanical equipment, and apply the fault finding techniques to find out the root causes of fault. This information is very useful to locate the fault. Other faults may include improper operating voltage, mechanical failure of components, and excessive heating or corrosion. External Short Circuit of Power Transformer. The following sections will outline the basic electrical concepts. This course is designed to provide basic electrical skills to those who need to perform first-line electrical maintenance tasks including the safe isolation, replacement and testing of a range of common electrical devices (motors, sensors, heating elements, solenoids, etc. electrical / electronic symbols, units and terms. Check that all components are in the correct position and orientation.
