Product describe

S150 transformer 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.

The host uses high speed microprocessor and 3.5 inch color LCD screen to display the size and waveform of the measured current in real time. Using FFT transform, digital filtering and other techniques, the test data is more accurate; it has the alarm critical value setting and alarm indicating function; it has the function of setting date and time; it has automatic shutdown function; it has set function. Sample number function; 200 groups of data and waveform can be stored.
The current clamp uses the special alloy and the latest magnetic shielding technology, the external magnetic field is small, and the anti-interference ability is strong. It ensures the high precision, high stability and high reliability of the perennial uninterrupted measurement. The inner diameter of the jaw is 52mm, the clamp below 52mm or below the cable or grounding wire, portable pincer design, no need to break the measured line, non-contact measurement, safe and fast.
The data software has the function of historical data query, dynamic display, waveform indication, alarm setting and alarm instruction, and has the functions of reading, checking, saving and printing of historical data.
