Grounding Down Conductor Continuity Tester Product Alias:

Grounding down conductor continuity tester, grounding continuity tester, ground network continuity tester, earth network continuity tester, conduction tester.

The reliable and effective connection between the grounding down conductor and the ground network of the GYDT-III grounding down conductor conduction tester is the fundamental guarantee for the safe operation of the equipment. In the long-term operation process of power equipment, the connection may be affected by factors such as moisture, and the node may be corroded and even broken, resulting in the increase of resistance at the connection point between the grounding lead down wire and the main grounding network, so as to fail to meet the requirements of the power regulations. This tester is used to measure the on-resistance value between the grounding down conductors of various power equipment in the substation.

Product features: 1. The output current is 10A, with strong anti-interference, and the output current delay function;

2. Constant current output, no need for manual adjustment, and no need for short-circuit zeroing;

3. The test efficiency is extremely high, there is no charging and discharging process, and it only takes 2 seconds to complete a point measurement;

4. The operation is simple, just press the measurement button, and the measurement results can be obtained;

5. DC resistance measurement, eliminating the influence of the test resistance value and the measured resistance;

6. The panel and the chassis form an integrated structure, which has good seismic resistance.

"Grounding down conductor continuity tester" is used for the continuity detection of the connection part of the power equipment and the ground grid in the engineering test of the power sector, with an output current of 10A, which is the current output value specified in the national standard, and the national reference standard: DL T475-2006.

At present, there are many manufacturers of "grounding down wire continuity tester", and it is not expensive. The reason is that the technical content of this product is not very high, buy a 10A constant current source, add a circuit board, and you can make it. At present, there are two main types of "grounding down conductor continuity testers" on the market:

One is the "GYDT-III Grounding Down Lead Continuity Tester", which is a basic type, with an output current of 10A, a range of 0-1999 m, and the basic functions can meet the national standard. The other is the "GYDT-II Grounding Down Lead Continuity Tester", which is an extended model that subdivides the current into four gears, 1A, 2A, 5A, and 10A.

Measuring range: 0-1999 m. The purpose of the subdivision current is to increase the range of the resistor, but the test continuity value is still 10A.

Some manufacturers increase the current to 20A, which does not meet the national standard, is undesirable, and has no practical significance.

The electrical integrity of the grounding device refers to the electrical connectivity between various electrical equipment, the parts of the grounding device and the equipment that should be grounded in the grounding device, that is, the DC resistance value, also known as the electrical continuity. The reliable and effective connection between the grounding conductor of the power equipment and the ground grid is the fundamental guarantee for the safe operation of the equipment. In the long-term operation process of power equipment, the connection may be affected by factors such as moisture, and the node rust and even fracture may occur, resulting in the increase of resistance of the connection point between the grounding lead wire and the main grounding network, so as to fail to meet the requirements of the power regulations, so that the equipment has unsafe hidden dangers in operation, and in serious cases, it will cause the equipment to lose ground operation.

The newly promulgated "Preventive Test Regulations for Electrical Safety Equipment" requires that the DC resistance test of the portable short-circuit grounding wire and personal protection grounding wire must be done on a regular basis.

The Ground Down Lead Continuity Tester is a highly automated portable tester designed to measure the DC resistance of portable short-circuit grounding wires as well as personal protective grounding wires. The instrument adopts high-performance single-chip microcomputer control, which can realize the intelligent testing process, simple and convenient operation, high precision, fast test speed, good retest, intuitive reading, and is an ideal special instrument that meets the requirements of the regulations, which greatly facilitates the development of test projects and improves work efficiency.

This product meets the requirements of the national standard GB6587-86 "General Outline of Environmental Testing of Electronic Measuring Instruments" and GB6593-86 "Quality Verification Rules for Electronic Instruments".
