2. During the test, the connection between the inverter resonant system and the transformer casing under test is based on the special ground wire provided by our company.
Transformer Induction Withstand Voltage Test Principle and Precautions for Variable Frequency Series Resonance Test Equipment The transformer induction withstand voltage test is a basic test for simultaneously testing the main insulation and longitudinal insulation of the transformer. The test voltage is generally twice the rated voltage. To avoid saturation of the core, the test frequency should be more than twice the rated frequency. Generally, the test frequency is between 100-400 Hz. Experience has shown that the test frequency is 150-200 Hz.
Audio Video Cable:Video cable, referred to as video cable, is composed of video cable and connector. Among them, video cable is coaxial shielded cable with characteristic impedance of 75 Ω (Ω). Common specifications are divided into - 3 and - 5 according to wire diameter, single core wire and multi-core wire according to core wire, common specifications of connector are divided into pressure joint and welding joint according to cable end connection mode, and equipment There are BNC (commonly known as bayonet) and RCA (commonly known as lotus head). Audio cable, referred to as audio cable, is composed of audio cable and connector. The audio cable is generally a dual core shielded cable, and the common connectors are RCA (commonly known as lotus head), XLR (commonly known as XLR head) and trsjacks (commonly known as pen plug).
