Surge Generators and Surge Protection Testing Methods
With evolving technologies, the use of Surge Generators has increased greatly. However, the surge voltages can put a strain on electrical systems and the safeguards in place to protect them. It is critical to learn about the state of one’s system and surge protection early on before actual problems arise. Surge protection testers are used to evaluate Surge Protective Devices (SPDs) and their components on-site. The Nominal Voltage and Leakage Current can be measured over a large test range with this simple process. This article will look into what a surge generator is, surge protection testers, and their advantages as well.

Surge generators are devices that are used to evaluate a system’s immunity by creating transient high-voltage surges. Impulse current generators and impulse voltage generators are the two forms of these generators. High impulsive currents are necessary to test various equipment such as plasma devices and lightning arresters, for which this generator is employed. They are usually large benchtop machines that are grounded for safety. Large coupling/decoupling networks are required when evaluating three-phase power line systems, resulting in a larger system size.
Surge generators, such as ones supplied by LISUN, produce significant spikes in voltage or current known as surge waves or combination waves when they are turned on. As a result of their existence, surge pulses cause short circuits or electrical equipment malfunction. When two waves combine to form a composite wave, the direction, amplitude, and phase of the composite wave must be taken into account by the two waves. Surge generators can be rented by test engineers to use during EMC testing to determine the immunity of a component or system.
Because electrical substations must maintain power supply even in extreme situations, it is critical to eliminate sources of EMI in the product design and ensure EMC compliance. Surge generators provide a wide range of output voltage ranges, allowing these applications to be tested.
Surge Protection Tester
Surge Protective Devices (SPD) and SPD components are tested on-site with Surge Protective Devices Testers. The Nominal Voltage and Leakage Current can be measured over a large test range with this simple process. An easy-to-read LCD display allows users to evaluate the state of these components based on the tester readings. To produce highly accurate results, precise auto-sensing shutdown and audible function indicators are used.
Types of Testing
Both types of SPD components can be measured by such testers. Types of Voltage Limiters such as Zener Diode, MOV, TVS can be tested as the surge protective device tester measures the Nominal Voltage by injecting a current of 1mA into the component. The tester can then use this voltage to determine the component’s leakage current.
The other type of testing involves Voltage Switching such as Spark Gap, Solid Discharge Tubes, and Gas Discharge Tubes. Here, the SPD tester measures the component’s breakdown voltage by injecting an increasing voltage (10V/ms) into it.
How is Surge Protection Testing Done?
The surge protective device’s plugs are inserted into the test tray that corresponds to them. The real testing is carried out by a computer. All test results are saved in the surge protection tester’s internal memory. The test results can be printed right now or at a later time. The test report includes the order number, the test result, as well as the date and time.
Advantages of Surge Protection Tester
Surge Protection testing has a number of advantages. This includes using the tester as a precautionary check which will help determine the current status and health of surge protection devices. Furthermore, a high level of quality and safety can be ensured since the testing algorithms are automatically adjusted or updated, allowing you to be up to date at all times. You can also take advantage of digital added value and services which provides a better idea of the issue at hand.
