Transformer Core Ground Current Tester

The Transformer Core Ground Current Tester is meticulously designed and manufactured for on-site online testing of transformer core ground current, leakage current, frequency, and waveform in power systems. It consists of a main unit, current clamp, data software, communication cables, and more. Power transformers are crucial electrical equipment in power systems, and any fault during operation can have severe consequences for the power system. A transformer core operating normally is single-point grounded; however, if two or more points are grounded simultaneously, a current loop will form between the core and the earth, with high currents reaching up to dozens of amperes, potentially causing local overheating or even burning of the core. This instrument can quickly detect latent faults in transformers, serving as a key tool for ensuring safe operation and regular maintenance of transformers. It is primarily used for testing leakage currents in transformer cores and clamps in substation and power plant settings, as well as for electrical equipment like reactors. It can also be applied in various fields such as power, communication, meteorology, railroads, oil fields, construction, measurement, scientific research, and educational institutions for testing currents and leakage currents in lines or equipment.

The main unit features a high-speed microprocessor.3.5A 4-inch color LCD screen, which can display the size and waveform of the measured current in real-time; utilizesFFTOur technology, including transformation and digital filtering, ensures more accurate test data; features alarm threshold setting and indicator function; includes date and time setting capabilities; offers an automatic shutdown function; allows for sample number setting; stores data and waveforms.200Group.

The current clamp is made with a special alloy and incorporates new magnetic shielding technology, minimizing the impact of external magnetic fields and enhancing its anti-interference capability. This ensures high precision, stability, and reliability in continuous measurements year-round. The inner diameter of its clamp is:φ70mmClamping φ70mmThe following cables or ground wires feature portable clamp design, allowing for non-contact measurements without disconnecting the circuit being tested, ensuring safety and speed.

The data software features historical data querying, dynamic display, and waveform indication; it includes alarm value settings and alarm indication; and offers functions for reading, reviewing, saving, and printing historical data.
