Basic Electrical Engineering Tools, Devices and Their Uses

Electrical engineers are required to work in hazardous environments near energized equipment. There are certain tools they require to carry out their job effectively and safely without causing any harm to themselves and those around them.

Electronic Measuring Probes
Current Probes
Current probes are one of the key tools that electrical engineers use to take measurements when the standard clamp on probes can’t reach. These may include tight breaker panels, wrapped around irregular shapes, and large buss bars. This sensor is highly flexible and has an output to provide direct readings for loggers, power quality instruments, DMMs and Oscilloscopes.In the old days, phase tester also was used to indicate the live wire in AC system.

Voltage or Current Meters

Digital Voltmeters DVM

DVMs are usually used to measure voltage and are general instruments for electrical engineers that are used in laboratories and in the field. They are the most commonly used instruments as they display voltage on LEDs or LCDs in a certain format that is easier for electrical engineers.

Voltage Testers

A voltage tester, as the name suggests, is used for testing the presence of voltage in a circuit. A voltage tester has a neon bulb with two wires attached to its bottom. This is used to test the flow of current in a wire. A good voltage tester is rated for up to 500 V. in the old days, Phase Tester also were used for this purpose.

Signal Generators

Function Generators

A function generators is a type of testing equipment or software that is used to generate different sorts of waves, in different forms that range over different frequencies. The most commonly forms of waves are sine, square and triangular. These shapes are produced by the function generator in the process of repairing electronic equipment.
