YDeLi S150 transformer Subway core Current tester

The S150 transformer core grounding current tester is specially designed for the on-the-spot on-line measurement of the grounding current, leakage current, frequency and waveform of the transformer core in the power system. It is composed of host, current clamp, data software, communication line and so on. The power transformer is the most important electrical equipment in the power system. Once it fails in operation, it will cause serious consequences to the power system. The core of the normal operation transformer is single point grounding. If there are two or more points at the same time, the current loop will be formed between the core and the earth. The maximum current can reach dozens of amperes, which will cause the iron core to be partially overheated and even burned. This instrument can detect latent transformer faults as soon as possible, and is the main tool to ensure the safe operation and normal maintenance of transformers. It is mainly applied to the leakage current test of the core and clip of electrical equipment such as transformers and reactors in substations and power plants. It can also be used to test the current and leakage current of electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields.
