With the widespread popularity of electrical products, user safety has become a top priority that cannot be ignored. In order to ensure that every appliance can provide users with a safe and secure experience, safety testers play a vital role. From withstand voltage test to insulation resistance test, to leakage current test and grounding protection test, each safety test item is carefully designed and strictly controlled to ensure the safety and reliability of the product.
Withstand voltage testIt is a key test to ensure that electrical products can maintain excellent insulation performance in high-voltage environments. This test tests the dielectric strength of electrical products by applying up to 5000V AC or 6000V DC.
Insulation resistance testThe insulation state of electrical products is evaluated by measuring the insulation resistance of electrical products under a certain DC voltage (such as 500V or 2500V). This test helps to find out if the insulation performance of the appliance has deteriorated due to moisture, dirt, insulation breakdown or aging.
Leakage current testIt is an important means to evaluate the safety performance of electrical products. In the test, the leakage current from the power supply to ground is measured by simulating the impedance of the human body. The lower this number, the higher the safety performance of the product, ensuring that the user does not suffer the risk of electric shock when using the appliance.
Grounding protection testthen verify whether the grounding system of the electrical product is effective. In the test, the continuity of the ground loop and the on-resistance or on-voltage drop are checked by applying a constant-current power supply. This test is designed to ensure that the grounding system can quickly direct dangerous voltages to ground in the event of a failure of the electrical product's basic insulation, thereby protecting the user.
Under these strict safety tests, the safety tester has become a solid barrier to protect the safety of electrical products. With its precision and reliability, it ensures that every piece of electrical product has undergone comprehensive and rigorous testing before entering the market.
