EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61643-311 testing. IEC 61643-311 applies to gas discharge tubes (GDT) used for surge protection in telecommunications, signaling and low voltage power distribution networks with rated system voltages up to 1 000 V (rms) AC and 1 500 V DC.
This standard contains a set of test criteria, test methods, and test circuits for determining the electrical properties of two- or three-electrode GDTs.
The standard defines the main performance characteristics of a GDT, including maximum discharge voltage, energy handling capacity, operating voltage, continuous discharge current, power frequency insulation withstand voltage, and impulse withstand voltage. It also provides test procedures for type testing and comprehensive testing of GDTs.
The standard specifies test circuits for GDTs used to evaluate performance characteristics. These test circuits simulate the operating conditions that GDTs are likely to encounter in real use, such as lightning surges, switching surges, and power frequency overvoltages. The standard defines parameters such as voltage and current waveforms, rise times and times for these test circuits.
IEC 61643-311 is intended for use by GDT manufacturers, designers and installers, as well as end users who need to select and install surge protection devices in power systems.
EUROLAB assists manufacturers with IEC EN 61643-311 test compliance. Our test experts offer the best service and controlled testing process in our laboratories to you, our manufacturers and suppliers, with professional working mission and principles.
