Temperature Measurement Method for Distribution Boxes
ASTM D3103 is a standard test method that determines the thermal performance of insulated shipping containers and packaging systems. This test method is often used for distribution. Heat generation in electrical components follows Joule's first law – it's literally the energy tax we pay for moving electrons. The formula is simple: Heat = I²R. It is particularly suitable for high-value or high-risk items that require high-precision internal temperature control, such as biological materials, pharmaceuticals, and blood. Measurement of temperature distribution is an important task in power engineering and energy auditing, engineering, construction, oil and chemical industry, transport, medicine, and others. The apparatus is based as closely as possible on ASTM C1363 (the accepted standard for conventional hot boxes). However, a number of improvements have been. To achieve this goal, a prototype constructed from expanded polystyrene is developed, incorporating an active ventilation system to ensure cold temperature uniformity. Thermocouples are integrated into the device to monitor the temporal temperature evolution with and without ventilation.
