High Voltage Tests
Periodic tests and controls of transformers and other MV equipment are required.
Belcert Certification performs the following tests.
Power Factor test,
Conversion Rate test,
Winding Resistance test,
DC Isolation test,
Magnetizing Current tests,
Mechanical and electrical tests of the tap changer,
Frequency Analysis tests (FRA),
Dielectric Analysis tests (Dırana),
Transformer Oil Tests,
Esis Mühendislik performs and reports Transformer maintenance and tests with its accredited devices with advanced technology and its expert staff.
Electrical safety testers, often called hypot testers, are an integral part of electrical and electronic equipment manufacturing. These testers generate high potential for testing dielectric strength and insulation resistance.
In addition, many hypot testers measure low resistance and provide low resistance / high current outputs to test ground resistance and ground bond integrity.
Electrical safety tests aim to detect faulty components or assembly errors, reveal hidden area faults and fulfill labeling requirements for many electrical and electronic equipment, thus reducing warranty costs.
It is carried out by applying voltage between the live cable/busbars and the outer casing of the device. The test result is declared as either pass (pass) or not (fail).
The tester is turned on for testing. Voltage is ed as AC/DC the program on the device.
Unless otherwise specified, the power of the High Voltage source must be at least 500 VA.
If the test voltage is AC, it will be applied to the device to be tested.
voltage calculation is 2 * U nominal (if 220V ac)+1000 V= approximately 1500V ac.
If DC is desired as test voltage, voltage calculation to be applied to the device to be tested
DC: U dc=Uac * 1.5 example ; U dc = 1500 V ac * 1.5 = 2.250 V dc.
