Handy Test Equipments For the ElectriciansMohamed Bedawy
Electrical test equipments are used by electricians to check responses and create signals from the devices under test. These equipments are essential for any electronics systems. Available at the stores, these equipments make the work easier for the electricians. Some of the major electricians test equipment includes the following:
These are electrical test apparatus that are used for the measurement of voltage, current, resistance, frequency and signal power. Analogue multimeter’s functionality includes electrical potential in volts, resistance in ohms, and current in amps. Short circuit problems can be found using the analogue multimeter.
More features like capacitor, diode and IC testing modes are available in the more advanced version. Common properties of this test equipment are battery power, range switch, temperature compensation, overload protection, mirrored scale, diode test and battery test.
A digital multimeter accompanied with a good wiring diagram and a good meter can find out the cause of any electrical problem. For accuracy in testing, digital multimeter is a must. This equipment tests voltage, current and resistance. It is widely used and more preferred than the analogue ones.
This equipment is an electronic tool that records data over time. The sensors built in the apparatus help in testing the cause of any electrical problems.
Electric motor testing
With increase in the frequency of corporate re-engineering, electric motor testing has lost its popularity. This testing is made to improve the readiness of the equipment and reduce capital overhead. Maintenance and management tools in the equipment assists the maintenance engineer in electric motor systems.
It tests the reliability of windings or cables in motors, switchgear, transformers and electrical installations.
Power quality analyzer
This testing equipment measures electric power signals. It also helps in determining the load’s ability to function properly with that electric power. The apparatus tracks various factors like AC voltage, AC current, and frequency.
Electricity meter test equipment
Energy meter test equipment can be utilized for testing the right amount of energy recorded which is generally in kilowatt-hours or cubic feet of natural gas consumption. It also measures the energy supplied to business or residential areas.
Portable appliance testing equipment is largely used in UK for routine check for safety. To ensure safety of the people who work with electrical appliances daily, this test is required. This test is done from time to time for maximum protection to the people. Records are maintained in log books and the evidence of the testing can be seen in the various labels of the tester. Any competent person who has knowledge about electricity can perform the PAT test and check for electrical safety.
These are the basic equipments used in checking the proper working and safety of various electrical equipments.
