Lucyelec 8100B Transformer Core Grounding Current Tester

8100B Transformer Core Grounding Current Tester is specially designed and manufactured for testing grounding current and leakage current of transformer core in power system on site. The instrument is composed of host meter, current clamp, monitoring software and communication cable. It can find transformer latent faults as soon as possible, which is the main tool to ensure transformer safe running and normal maintenance.

The instrument has anti-interference ability and can be used in the environment of strong magnetic field interference near the transformer. It is mainly apply to the leakage current test of iron core and clamps comment of electrical equipment such as the substations and power station as transformers and reactors. It can also be used for current and leakage current test of lines or equipment in electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. Please contact Lucyelec for more details.

Lucyelec 8100B Transformer Core Grounding Current Tester

General Description:

8100B Transformer Core Grounding Current Tester is specially designed and manufactured for testing grounding current and leakage current of transformer core in power system on site. The instrument is composed of host meter, current clamp, monitoring software and communication cable. The power transformer is an important electrical equipment in the power system, once the fault occurs in the running, it will cause serious consequences to the power system. The normal running of the transformer core is a single grounding point, if there are two or more points grounding at the same time, the iron core and the earth will form a current circuit loop, the maximum current can up to dozens of amperes, will cause the core local overheating or even burned. This instrument can find transformer latent faults as soon as possible, which is the main tool to ensure transformer safe running and normal maintenance.The instrument has anti-interference ability and can be used in the environment of strong magnetic field interference near the transformer. It is mainly apply to the leakage current test of iron core and clamps comment of electrical equipment such as the substations and power station as transformers and reactors. It can also be used for current and leakage current test of lines or equipment in electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields.

Features and Advantages:

The host adopts high-speed microprocessor, 3.5 inch color touch LCD screen, intelligent touch operation, convenient and fast. It can display the magnitude and waveform of the measured current in real time. Adopt FFT transform and digital filter technology to make the test data more accurate. With alarm threshold setting and alarm indication function; Date clock and setting function; Automatic shutdown time function; the function of setting sample number;With USB interface, the stored data can be imported into the computer, and the instrument can store 200 groups of data and waveform.

The current clamp core is made of Permalloy alloy and adopt magnetic shielding technology, which has little influence on the external magnetic field and strong anti-interference ability, ensuring the high precision, high stability and high reliability of uninterrupted measurement all year round. Its clamp jaw diameter is 80mm×80mm, can clamp the cable or grounding line below 80mm, or clamp 96mm×4mm flat steel grounding line, portable clamp design, do not have to disconnect the tested line, non-contact measurement, safe and fast.

Monitoring software has on-line real-time monitoring and historical query function, dynamic display, waveform indication; With alarm value setting and alarm indication; With historical data reading, consult, save, print and other functions.
