A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter , and often suffices for checking for the presence of voltage on a conductor.
A common label for certifying that a device has been tested. In electrical safety testing, portable appliance testing (PAT inspection or PAT testing) is a process by which electrical appliances are routinely checked for safety, commonly used in the United Kingdom, Ireland, New Zealand and Australia.
A dielectric voltage withstand test (also known as a hipot test) is done by applying a voltage higher than operating voltage to the device or installation under test. In this test, the electric insulation of a product or installation is put under a voltage stress much higher than its normal operating voltage.
Electric power quality is the degree to which the voltage, frequency, and waveform of a power supply system conform to established specifications. Good power quality can be defined as a steady supply voltage that stays within the prescribed range, steady AC frequency close to the rated value, and smooth voltage curve waveform (which resembles a sine wave).
February The Académie des inscriptions et belles-lettres (Academy of the Humanities) is founded in Paris. [1]Katherine Philips' translation of Pierre Corneille's Pompée is produced successfully at the Theatre Royal, Dublin (Smock Alley Theatre) in Ireland, as the first rhymed version of a French tragedy in English and the first English play written by a woman to be performed on a ...
In December 1663, Fugen-dake erupted, producing lava flows that covered forest for over an extension of 1 km (0.62 mi). In the spring of the following year, there was a flood from the Kujuku Island crater, located on the southeastern flank of Fugen-dake at an altitude of 600 metres (2,000 ft). More than 30 were killed. [5]
