IEC/EN61000-4-5, IEC/EN61850-3, ITU-T K.12, ITU-T K.20, ITU-T K.45, UL1449

2. Introduction of Lighting Surge System:

LSG-6K10 Lighting Surge System includes: 1.2/50ms Surge Generator, single phase CDN, Voltage waveform attenuator, current waveform attenuator, voltage wave peak ( or the residual voltage wave peak) testing equipment, current wave peak testing equipment, EUT working current and voltage testing equipment.

LSG-6K10 Lighting Surge System is confirmed to IEC61000-4-5 and GB/T17626.5. It is the equipment used for Anti-Surge performance test for electronic and electrical products in the industry process measurement and control device. It includes Coupling/ Decoupling Network (CDN), which can be used for the Surge immunity test in the power line.

3. Features of Lighting Surge System:

1). 7 inches LCD touch screen, with plentiful functions, easy to operation and update the software.

User can design the test program, and has 1000 groups memories.

2). Monitoring the surge voltage and current waveform by work with an external oscilloscope.

3). Built in single phrase 10A (16A) network, makes the equipment smaller and convenient.

4). With high-strength plug in the panel, EUT can connect with the equipment convenient and reliable.

5). Monitoring the work voltage and current of the EUT. Overvoltage protection and overcurrent protection.

6). Intelligent test the surge output, warning at voltage error and no output.

7). Intelligent judge the abnormal of high voltage and surge output.

4. Parameters of Lighting Surge System:

5. Initial Interface of the Lighting Surge System

There are two main reasons causing lightning shock:

- Switching Transients:

Switching transients is related with the following factors:

• The switch disturbance of the main power supply, such as the switching of capacitor bank.
• The start or stop of other devices near the tested equipment, as well as the changes of the load in the power distribution system.
• Switching the SCR device with resonance circuit.
• All kinds of system failures, such as short circuit and arc fault of equipment grounding network or grounding system.

- The Lightning Transient

The generating mechanism of lightning transient:

1. The lighting hits directly external (outdoor) line and injects large amount of current, which flows through the ground resistance or surge impedance generates voltage in external line.
2. Indirect lightning (clouds within or lightning between clouds) may induce voltage in the circuit line in or out the building.
3. It will form an electromagnetic field when a lightning shock did not hit the line but the objects near the line and the electromagnetic field can cause the induced voltage of the external circuit line.
4. The generated interference is produced when lightning current nearby equipment discharges directly and the lightning ground current flows and couples in the public grounding system of equipment.
5. In addition, the rapid changing of current and voltage may also be coupled into the interior of the equipment when some protectors of the equipment are incentive.
