Impulse Voltage Generators | Impulse Generators

The SUG255 Series Impulse Voltage Generators | Impulse Generators is a high-precision testing device focused on insulation performance detection of electronic and electrical equipment. The function is to output standard 1.2/50μs high-voltage impulse signals to simulate transient high-voltage shocks that equipment may encounter during actual operation (such as grid lightning-induced overvoltage, switch operation overvoltage, etc.). It evaluates the insulation withstand limit of the Equipment Under Test (EUT), identifies insulation weak points in a timely manner and prevents safety accidents (e.g., leakage, short circuit, or even equipment burnout) caused by insulation failure.

The SUG255 Series Impulse Generators equipped with a large-sized Android touch screen supporting both English and Chinese, it is widely used to meet EMC compliance testing needs in multiple fields, including LED lighting, medical care, power systems, industrial control, new energy charging piles, small and medium-sized motors, low-voltage electrical appliances, electricity meters and household appliances.

Applications:
1. Motor and Electrical Equipment Field
• Insulation Testing for Small and Medium-Sized Motors: In accordance with the GB 14711 standard, it tests the insulation performance of stator windings and rotor windings of small and medium-sized rotating motors (such as asynchronous motors and synchronous motors). Through 1.2/50μs high-voltage impulses, it verifies the motors’ insulation withstand capacity under start-stop conditions or lightning interference, preventing motor burnout or leakage caused by insulation breakdown.
• Low-Voltage Electrical Appliance Testing: For low-voltage electrical appliances such as circuit breakers, contactors, and relays, in accordance with the GB/T 14598.3 standard, it tests the insulation strength between their coils and housings, as well as between contacts and coils. This ensures that the appliances do not experience insulation failure under rated voltage and transient high voltage, safeguarding electrical safety.

2. Wire & Cable and Connector Field
• Wire & Cable Insulation Verification: In accordance with the GB/T 3048.8 and IEC 60060-1 standards, impulse withstand voltage tests are conducted on power cables, control cables, communication cables, and other cable types. These tests evaluate the integrity of cable insulation layers under high-voltage impulses, identify issues such as insulation layer damage or aging, and prevent short circuits or signal interference caused by poor insulation.
• Connector & Terminal Testing: It tests the insulation performance of connecting devices such as plugs, sockets, and terminal blocks, verifying their insulation reliability during plugging/unplugging moments or under transient high voltage. This prevents electric shock accidents caused by poor contact or insulation breakdown.

3. Electric Meter and Metering Equipment Field
• Electric Meter Insulation Compliance Testing: In accordance with the standards of GB/T 17215.301, IEC 62053-61, GB/T 17215.322, and IEC 62053-22, impulse withstand voltage tests are conducted on multi-function electric meters and static active electric meters (Class 0.2S / Class 0.5S). These tests ensure that the insulation performance of electric meters meets standards under grid fluctuations or lightning-induced interference, preventing metering data deviation or equipment damage.
• Metering Transformer Testing: It tests the insulation strength of current transformers and voltage transformers, verifying their insulation stability in high-voltage environments to ensure the accuracy and safety of the metering system.

4. Consumer Electronics and Household Appliances Field
• Household Appliance Safety Testing: For household appliances such as refrigerators, washing machines, air conditioners, and televisions, in accordance with the IEC 60065 and GB 4706 series standards, the insulation performance between the appliance’s power cord, internal circuits, and housing is tested. This simulates transient high-voltage shocks from the power grid, ensuring no leakage occurs during the use of household appliances and meeting national safety certification requirements.
• Audio-Visual Equipment Testing: For audio-visual equipment such as speakers, TV boxes, and projectors, impulse withstand voltage tests are conducted in accordance with the IEC 60065 standard. These tests evaluate the insulation strength of the equipment’s power modules and signal interfaces, preventing equipment malfunctions or user electric shocks caused by insulation failure.

5. Information Technology and Industrial Control Field
• IT Equipment Insulation Verification: In accordance with the IS 13252-1 standard, the insulation performance between the power input ports and housings of information technology (IT) equipment (such as computers, servers, and routers) is tested. This ensures the insulation safety of the equipment in complex power grid environments and prevents equipment downtime or data loss caused by transient high voltage.
• Industrial Control Equipment Testing: For industrial control equipment such as PLCs (Programmable Logic Controllers), frequency converters, and sensors, the insulation strength between their power terminals and signal terminals is tested. This verifies the insulation reliability of the equipment under high-voltage interference in industrial sites, avoiding production line control failure caused by insulation breakdown.
