BS0212 Transformer Core Grounding Current Detector

Product Introduction

The BS0212 transformer core grounding current detector is specially designed and manufactured for on-site online testing of transformer core grounding current and leakage current in power systems. It consists of a host, current clamp, monitoring software, communication lines, etc.

Power transformer is the most important electrical equipment in the power system. Once a fault occurs during operation, it will cause serious consequences to the power system. The core of a normally operating transformer is grounded at a single point. If two or more points are grounded at the same time, a current loop will be formed between the core and the ground, with a maximum current of several tens of amperes, which will cause local overheating or even burning of the core.

The BS0212 transformer core grounding current detector can quickly detect latent faults in transformers and is the main tool for ensuring the safe operation and normal maintenance of transformers. It is mainly suitable for leakage current testing of iron cores and clamps in electrical equipment such as transformers and reactors in substations and power plants. It can also be used for current and leakage current testing of lines or equipment in fields such as power, communication, meteorology, railways, oil fields, construction, metrology, scientific research and teaching units, and industrial and mining enterprises.

Product Features

1. Adopting high-speed microprocessor, 3.5-inch color touch LCD screen, intelligent touch operation, convenient and fast.

2. Real time display of the magnitude and waveform of the measured current

3. Using FFT transform, digital filtering and other techniques to make the test data more accurate.

4. It has alarm threshold setting and alarm indication functions, as well as date clock and setting functions.

5. It has the function of automatic shutdown time and setting the sample number.

6. Equipped with a USB interface, it can import stored data into a computer, and the instrument can store 200 sets of data and waveforms.

7. The current clamp is made of special alloy and adopts the latest magnetic shielding technology. It has little influence from external magnetic fields and strong anti-interference ability, ensuring high precision, stability, and reliability of uninterrupted measurement all year round. Its clamp inner diameter is 80mm × 80mm, and it can clamp cables or grounding wires below 80mm in diameter, or clamp 96mm × 4mm flat steel grounding wires. The portable clamp design does not require disconnecting the tested line, and non-contact measurement is safe and fast.

8. The monitoring software has online real-time monitoring and historical query functions, dynamic display, and waveform indication.

9. Equipped with alarm value setting and alarm indication

10. It has functions such as reading, querying, saving, and printing historical data.
