electrical testing equipment and its various types

Electrical testing equipment is used to capture responses and create signals from electrical devices. These are used for the proper functioning of the electrical systems.

Types:  

The various types electrical equipments used for testing are-

Ammeter- Ammeter is an instrument used for measuring current in an electric circuit. Amperes is used for measuring electric currents. Micro ammeters and milli ammeters are used for measuring smaller currents in microampere or miliampere range. The ammeter consists of two leads that are connected in a circuit to different points. The amperage is measured passing the current through the resistor array where the heat is generated in section to the measuring of amperage.

Voltmeter ? the electrical potential difference is measured in an electric circuit between two points using a voltmeter. Digital voltmeters display numerical voltage by using the converter to transform the analog signal to a digital one. Analog voltmeters in the circuit moves proportionately across the scale according to the circuit?s voltage. There are different styles of voltmeters. Good voltmeters can measure voltages from hundreds of volts to millivolts. The polarity of current is shown by the voltmeters.  Solenoid voltmeters are specific voltmeters used widely to test power circuits. These are not easily damaged due to electrical overload or rough handling.

Moisture Analyzer


Cable tester- the electronic devices are verified using a cable tester which is wired assembly or connected in a cable. It consists of a voltmeter, electric current source and a matrix used for switching which is used to connect the voltmeter and the source of current to all the points of contact within a cable.

Multimeter- multimeter is an instrument which uses several combinations of measurement to operate in one single unit. The basic characteristics of a multimeter include the capability to measure current, voltage and resistance. It is used for measuring accuracy of very high degree.

Continuity tester- the electrical path is determined by the continuity tester which is created between two points of an electrical circuit. The tester is comprised of a source of electrical power with a series in an indicator. The electrical power sources include two test leads and a battery. The indicator is activated when the complete circuit is created between the leads used for testing.

The other electrical testing equipment includes Current Clamp, Growler, Megger, Hipot, Test Light, Rogowski coil etc.

Electrical test equipment manufacturers

The electrical equipment manufacturers supply test equipments directly to the customers in a very reasonable rate. The genuine equipments can be purchased from the manufacturers. Trouble shooting becomes much easier and maintenance of the energy system is fulfilled by using the products directly from the manufacturers. They state the processes of using these equipments in their various catalogues which is very helpful in our day to day life. Buying directly from them is also quite cost effective because the products are not passed through the retailing chains.

All types of equipments used for electrical testing are easily available on the internet. Persons interested in purchasing these can browse through the official websites of various manufacturers.
