Introduction Surge protection testing is a crucial aspect of ensuring the reliability and safety of electrical and electronic devices, especially in environments prone to lightning strikes and power surges. The surge protection tester plays a pivotal role in evaluating the immunity of equipment to these sudden voltage spikes. In this article, we will provide a detailed analysis of surge immunity testing, specifically focusing on the LISUN SG61000-5 Surge Generator, a leading surge protection tester designed to meet international standards such as IEC 61000-4-5. Overview of Surge Immunity Testing Lightning strikes and switching transients are major sources of high-energy surges, which can cause severe damage to electrical and electronic systems. To mitigate these risks, surge protection devices (SPDs) are employed, and their effectiveness is validated through surge protection testers. These tests simulate real-world surge conditions to evaluate how well the equipment can withstand such ...

Abstract The durability of rubber products is significantly affected by their exposure to environmental factors, particularly ozone, which induces cracking and degradation. This paper explores the process of accelerating rubber aging using the ozone test chamber, specifically the LISUN OTC-150A Ozone Test Chamber, and how controlled environmental conditions can simulate the long-term effects of ozone on rubber materials. By replicating the ozone-rich atmosphere, the chamber allows for faster testing, helping industries evaluate the longevity and durability of rubber products. This paper will delve into the technical specifications of the LISUN OTC-150A, the test procedures, and provide data on how various rubber samples respond under these conditions. 1. Introduction Ozone (O₃) is a reactive gas found in the atmosphere, which, even in small concentrations, can cause the oxidative degradation of elastomers. Rubber materials, when exposed to ozone, undergo chemical reactions that weaken ...

Abstract Light intensity, a key parameter in lighting design and testing, plays a significant role in the development of lighting products that meet international standards such as LM-79. The LISUN LSG-6000 LM-79 Moving Detector Goniophotometer (Mirror Type C) is an advanced instrument that provides precise measurement of light intensity distribution in three-dimensional space. This paper discusses the principles of measuring light intensity, the significance of LM-79 standards, and provides detailed insights into how light intensity is measured in goniophotometers like the LISUN LSG-6000. The paper also presents experimental data, supported by tables and figures, illustrating the capabilities of the LSG-6000 in evaluating light sources. 1. Introduction Light intensity is measured in candelas (cd), which quantify the luminous intensity emitted by a light source in a specific direction. Accurate measurement of light intensity is crucial for lighting manufacturers, particularly in assess...
