explain why all the load must be removed when to conduct the insulation and resistance testing
Portable appliance testing (PAT) is basically a method of testing (using a device and by sight) that any electrical equipment, cables, devices, machinery is safe to use.
One way of "Earth fault testing" is to use a High Pot device. This send a high voltage with a very low current through the equipment and will tell you when there is a leak to ground.
The different testing steps of HT and LT panel include commissioning, sanctioning, erection and the CPP set. All this is done in the servicing of the transformers and the HT/LT control panels.
This depends on the IC. Visual inspection will only go so far. You will need to test it and compare the testing to the datasheet; if it is not testing as specified in the datasheet, then it is bad. Sorry, there's no one easy answer for all IC's.
1. unit testing,integration testing, system testing, user acceptance testing. 2. unit testing, system testing , integration testing,user acceptance testing. 3. unit testing, system testing , user acceptance testing,integration testing. 4. unit testing, ,integration testing, user acceptance testing,system testing.
These are the next testing levels after unit testing: 1 Integration testing 2 Component interface testing 3 System testing 4 Operational Acceptance testing
It is testing of "how" the system works. Non functional testing may be performed at all test levels. The term non-functional testing describes the tests required to measure characteristics of systems and software that can be quantified on a varying scale, such as response times for performance testing. Types of Non-functional testing are performance testing, load testing, stress testing, usability testing, maintainability testing, reliability testing and portability testing.
Functionality testing is what is expected. Load testing is what it actually did.
There are 2 types of Testing 1.Manual testing 2.Automated testing
Yellow box testing is basically an error message testing.. Yellow box testing is basically an error message testing..
Validation testing is to test software if it meets its stated requirements. System testing is the testing of Software and Hardware together and to find out they both can work together to be successful application.
testing an answer
Website testing includes many techniques : Functionality Testing, Cross browser Testing, Usability testing, Interface testing, Compatibility testing, Performance testing, Security testing and Mobile Testing. For each and every technique there are many different testing tools available on the internet. These tools will be of great help. But they don't provide 100% results. So you must take the help of website testing experts or may outsource website testing services.
module testing
1.Path testing 2.Conditional testing 3.Loop testing
static and dynamic testing are basic types of testing
