On installed transformer a test is performed to check weather it has any oil leakage or not, the test is called pressure test, more precisely pressure leakage test.
absolute pressure; gauge pressure; atmospheric pressure...
magnetising current test, magnetising balance test, s.c test, vector group test, winding resistance test, ratio test
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
this test helps in finding the core losses and copper losses in single test , it is also called as back to back test or heat run test .
Procedure for sumpners test is the single phase transformer. This is a back to back test.
A test pressure whcih is used to perform hydro test is known as hydro test pressure, besically the hydro test pressure is more then the design pressure of pipe, tank, pressure vessel ..................
PN 16 static test pressure
Pressure test ?? Cooling system? A/C? Fuel Pressure? Compression?
A coolant pressure test is used to detect a leak on the coolant system.
Design pressure multiply by 1.1 equal pneumatic test pressure. Design pressure multiply by 1.5 equal Hydrotest Pressure Note: Design Pressure is different from Operating pressure. Design Pressure is equal to Maximum Operating Pressure From: galdo.gaspar@ymail.com

Test pressure
for ex; design pressure in pipe 100bar,and what is test pressure in pipe
it is the pressure test used to determine the operating pressure of the pressure relief valves (CDTP).
The point pressure leak test, also known as the Valsalva leak test
cold differential test pressure -The inlet static pressure at which a pressure relief valve is adjusted to open on the test stand. This test pressure includes corrections for service conditions of superimposed back pressure and/or temperature.
A pneumatic test is a type of pressure test where the vessel is pressurized using air or another gas to check for leaks or structural integrity. An air test is a specific type of pneumatic test where only air is used as the test medium. In both tests, the pressure vessel is pressurized, but the distinction lies in the specific medium used for pressurization.
