PSSBF triple frequency induction withstand voltage generator
PSSBF Triple Frequency Induction Withstand Generator Product Overview
PSSBF triple frequency induction withstand voltage generator is used for power transformers, voltage transformers and other tested products, in addition to the external high frequency test of the main insulation of the fully insulated transformer, but also the longitudinal insulation and semi-insulation of the transformer. The main insulation of the transformer is subjected to an induction high voltage test. According to the national test standards, the test voltage of the power transformer and the voltage transformer is approximately 2-3 times larger than the working voltage of the Zui. It is well known that the transformer is nearly saturated at rated frequency and rated voltage. If a test voltage greater than the rated voltage is applied to the transformer windings of the tested transformer by the commercial frequency power supply, the no-load excitation current will increase sharply, reaching an unacceptable level. It can be seen from the relationship of the induced potential that in order to apply a test voltage greater than the rated voltage without saturating the iron core, a method of increasing the power frequency can be used, and a power supply generator larger than the frequency multiplier must be used.

Nonsteroidal SARMS are alternatives to steroids, also known as selective estrogen receptor modulators. Unlike steroids, SARMS stimulates muscle more directly and more strongly than steroids. The stronger the targeting, the more targeted. SARMS is an optimized version of steroid substances that have steroid-like effects in the treatment of certain diseases. It may completely replace steroids in the future as a new and more effective drug.
