maintenance of electrical systems and control panels. There are many types of Power Supplies like AC – to – DC Power Supplies, Linear Regulators, Switching Mode Power Supply, etc.An alternative to bench power supply is to use a wall adapter as per the project requirement like 5V or 12V. Assembling electronics project and making it works is a good start in helping one to learn troubleshooting methods as well as becoming familiar with your tools, test equipment, electronic schematics and component color codes. Dec 15, 2015. Calibration and Preventative Maintenance. The following is a general procedure for use of test equipment: TYPES VOLTMETERS For measuring differences of potential (voltage) between two points in an electrical circuit. Shenzhen Zotek Instruments CO., LTD. is a high-tech company specializing in R&D and production of electronic & electrical measuring instruments. Maintenance & Testing of Electrical Equipments objective questions (MCQs) and answers for competitive & university exams. 20. 2 E. Test Equipment (15 of items) Includes knowledge of the proper use of various test instruments, such as multimeters, meggers, ductors, oscilloscopes, handheld communicators, high voltage meters, ammeters, and manometers. Maintenance work should only be undertaken by those who are competent to do the work, who have been provided with sufficient information, instruction and training (PUWER regulations 8 and 9). Electronic/bench testing equipment and supplies simulate operating conditions and perform functional tests to see if devices are working correctly. At Test and Measurement Instruments C.C. RCD tester. With high-risk or complex equipment, these demands may be significant and, in some cases, may be best undertaken by the manufacturer or specialist contractors. Fluke products: Test and measurement tools and software Fluke Corporation is the world leader in the manufacture, distribution and servicing of electronic test instruments and software. These electrical testing equipment tools perform tests on transformers, switches, circuit breakers, protective relays, rotating machinery, and associated cabling. Electronic components majorly work on DC Power Supply and hence having a reliable source of DC Power Supply is very important. Distributor of Fluke, Flir, Megger, GE, and Keysight. WAR DEPARTMENT Washington 25, D. C., 19 April 1945 TM 9-867, Maintenance and Care of Hand Tools, is published for the information and guidance of all concerned. Figure out the equipment and supplies you'll need throughout the work day and keep them close by. -- Diagnose malfunctioning systems, apparatus, or components, using test equipment and hand tools to locate the … How to use oscillo- scopes to measure different electrical quantities is also described. Mark Lamendola . At one time, it was common in many production facilities for the typical maintenance electrician to walk the floor with just a screwdriver and adjustable pliers in his back pocket. Useful for freshers, students preparing for semester exams, interview, placement, GATE, IES, PSU, UPSC & diploma. Another example of an ATE PCB repair system is the ABI Electronics System 8 – a board-test system that uses a selection of CD-drive-size modules to create a customized PC-driven PCB test station. Good tools can be quite an investment, but if you take good care of them, they'll return the favor. Fluke offers you a full range of electrical test solutions, from basic voltage detectors to energy loggers to 4-channel portable oscilloscopes, so you can get the job done right and go home safely. Current probes are one of the key tools that electrical engineers use to take measurements when the standard clamp on probes can’t reach. Calibration: A comparison of two instruments or measuring devices one of which is a standard of known accuracy (traceable to national standards) to detect, correlate, report or eliminate by adjustment, any discrepancy in accuracy of the instrument measuring device being compared to the standard. It can also extend the life of your instruments and equipment, saving you money. Test leads allow you to bypass a circuit and directly test a component by applying 12 volts from the battery. First, electrical contractors can prevent costly accidents. Test lights, also called circuit testers, are essential tools for determining whether voltage is present at particular points in circuits. … We are dedicated to supplying excellent test equipment, having been suppliers to our customers in excess of 30 years. Where circuits are protected by an RCD (residual current device) we must carry out a test to ensure that the device will operate very quickly under fault conditions and within the time limits set by the IEE Regulations. All jobs for electrical engineers call for testing tools and instruments. Selection of test instruments Regardless of whether you are performing electrical installation work, equipment maintenance, verifying the absence of voltage for de-energized work, troubleshooting, voltage measurements or similar diagnostic work, collecting accurate and consistent information from these tests is imperative.
