In and Out About Withstand Voltage Test Equipment

The primary use of a Withstand Voltage Test Equipment is for conducting electrical safely tests which in turn ensures trustworthiness of the product and thus the safety of the person using it. particle filtration efficiency tester

Each of these Withstand Voltage Test Equipment works on the principal of dielectric high potential (abbreviated as “Hipot”) tests which should be performed on an electric section to regulate the insulation properties.

This Withstand Voltage Test Equipment includes a hand-cranked generator which delivers high voltage and the same is calibrated rightly to its scale in Meg-ohms. The instrument is also known as “Hipot” tester and is mostly used for performing these kinds of Withstand Voltage Testing with a high voltage source and Volt/Amp meters where the testing instrument applies the required voltage to the test device and check up on the current outflow. The output currents shall trip a fault indicator. The Withstand Voltage Test Equipment has a range of 0.5 and 20 mA as a limit for the current outflow trip. This limit is typically chosen and regulate by the tester personal as per the features of the item under testing and voltage application rate. This process ensures that the tester personal select the settings such that it will not trip the tester incorrectly and also helps in identifying a setting that lessens likely damage to the device under test should an inadvertent discharge or breakdown occur.

The Withstand Voltage Test Equipment is equipped with overload protection for high outputs. While the test voltage could be AC or DC with VLF (0.01 – 0.1 Hz) or resonant frequencies (30-300 Hz) as per the suitability but in the range of the maximum voltage as per the test standard for that particular test device. The submission rate can be tuned up to manage leakage currents causing from inherent capacitive effects of the device under testing. Withstand Voltage Test Equipment do the test among conjointly insulated units of a part or energized parts and electrical ground. The Hipot test actually identifies a device’s capacity to safely operate during prescribed electrical environments. The Withstand Voltage Test Equipment is used, for both, a factory test on newly manufactured device and equipment which is used for its periodic maintenance check. The typical testing interval for such Hipot tests varies up to 60 seconds or above.

The tester should be aware of the fact that the applied voltage, rate of application and test duration totally subject to the description of the equipment which means that diverse test standards apply for consumer electronics, military electrical devices, high voltage cables, switch-gear and other devices.
