Test Principle as per Endurance Test as per IEC 60947-1

The Endurance Test, as per IEC 60947-1, is a crucial test that ensures the durability and reliability of electrical components. The principle behind this test is to evaluate the ability of component to withstand repeated operations over an extended period.

The main objective of the endurance test is to determine whether a component can maintain its performance characteristics after being subjected to continuous operation for an extended duration. This helps in identifying potential failure points and design flaws that may result in equipment breakdown or malfunction.

The testing involves applying load cycles on the component under controlled conditions until it reaches the specified number of cycles or fails due to wear and tear.

The loads are applied based on specific operating conditions such as current, voltage, temperature etc., which vary depending upon the type of equipment under consideration.

This test provides valuable insights into how well a product performs when subjected to prolonged use and can help manufacturers make informed decisions about product design improvements.

Apparatus Endurance Test as per IEC 60947-1

The apparatus used in the endurance test as per IEC 60947-1 is crucial to ensure accurate and reliable results. It consists of a test circuit, which includes a power source, switching device, and load. The power source should be able to deliver the required voltage and current for the entire duration of the test.

Switching device should be capable of carrying and breaking rated current without causing damage or excessive contact wear during operation. To achieve this, it must have appropriate mechanical strength, sufficient arc quenching capability and effective contacts protection.

The load bank simulates an actual electrical load by converting electrical energy into heat or other forms of energy that are dissipated into the environment.

It provides resistance to electric flow which enables measurements on how long device can withstand overloading conditions before failure occurs.

Other essential components include monitoring equipment such as ammeters, voltmeters, wattmeters, thermocouples among others that help in measuring various parameters throughout the testing period.

Choosing appropriate apparatus helps guarantee repeatability and accuracy while minimizing variations from one test cycle to another.

Procedure

The procedure for conducting an endurance test as per IEC 60947-1 involves subjecting the device under test to a predetermined number of switching operations at specified current and voltage ratings. The aim is to determine the durability and reliability of the device under harsh operating conditions.

Before commencing the test, it’s essential to ensure that all connections are secure, and the apparatus is functioning correctly. Next, set up the testing machine in accordance with manufacturer specifications while adhering to safety protocols.

After setting up everything, connect power supply sources and verify that they’re providing accurate voltages before applying loads. Once verified, start recording data such as voltage fluctuations during each switch operation using an oscilloscope or other measuring devices.

The sample must undergo repeated cycles until it reaches its final measured cycle count or failure point. It’s crucial to continue monitoring throughout this process while maintaining a record of all results obtained during testing.

Following a well-defined procedure ensures that accurate results are obtained from endurance tests as per IEC 60947-1 standards. Conducting these tests plays a significant role in verifying product quality by detecting potential weaknesses accurately early on in development stages before releasing them into production environments.
