5000h Insulator Multi Stress Testing Machine IEC 62730-2024

Remark:

The IEC 62730 standard is an international standard for multi stress aging testing of insulators used in photovoltaic (PV) systems, primarily evaluating the long-term durability of insulation materials in complex outdoor environments. The IEC 62730 Insulator Multi Stress Testing Machine is a testing device specifically designed to simulate the superposition of various environmental stresses and accelerate the aging of insulators.

Specification

Product name:	5000h Insulator Multi Stress Testing Machine IEC 62730-2024
IEC 62730:2024	In this document, the technical requirements of the 5000h multiple stress test bench are given according to IEC 62730:2024.
Test Procedur	The test shall be carried out in a moisture sealed corrosion-proof chamber, the volume of which shall not exceed 20 m3.
Test Conditions	The cycle of stresses applied to the insulators and repeated for a period of 5 000 h is shown in Figure 3. The cycle is designed so that the test specimens are also subjected to the effects of temperature variation and condensation .
Voltage	The power frequency test voltage in kilovolts is adjusted to the actual creepage distance of the test specimens. it is determined by dividing the creepage distance in millimetres by 34,6 (equal to a specific creepage distance of 20 mm/kV, calculated as phase-to-phase value) .
Solar Simulation	The simulated solar irradiation is provided by a xenon arc lamp with a nominal output of 6500 W and equipped with 2 boron silicate glass filters (see example in Figure 5) . The distance between the xenon lamp and test specimens is approximately 480 mm. A new lamp and filters shall be used at the beginning of each test. The filters and , if necessary, the lamp shall be replaced during the test according to the lamp manufacturer's recommendations .
Artificial Rain	The artificial rain shall be provided by nozzles mounted above the test specimens and outside their perimeter (see Figure 4 ). The average precipitation rate shall be in accordance with IEC 60060-1 . Water of a minimum resistivity of 85 nm shall be used. Each of the test specimens is sprayed individually.
Dry Heat	The chamber is heated up to 50 °C ± 2 °C; the time far the temperature to rise is 15 min as a maximum. NOTE it is recommended to heat and insulate the walls of the chamber.
Humidity	Nominal relative humidity: RH = 95 % ± 3 % at 50 °C.
Pollution	The pollution is simulated by a salt fog (salinity : 7 kg/m3 ± 5 %) sprayed by nozzles of the IEC 60507 type. The spray nozzles are mounted close to the bottom of the chamber and spray upwards towards the roof of the chamber. The fog should fiil up the chamber and not be directly sprayed on to the test specimen. Salt water prepared from NaCI dissolved in tap water should be supplied to the spray nozzles. The fog intensity and uniformity should be maintained in the specimen's exposure zone.
Salt fog calibration	The calibration will be carried out before the start of the test. At least two clean collecting receptacles with a collecting area of 8 000 mm2 ± 2 000 mm2 and a maximum height of 100 mm each are placed as close as practical to the position of the ends of the test object. The receptacles are positioned in such a way that they are not shielded by the test specimens and to avoid dripping from the construction elements of the chamber or another source. They should collect between 1,5 ml and 2,0 ml of precipitation per hour (corrected to 8000 mm2 collecting area) averaged over a minimum period of 16 h.
Recoding system	1- All test parameters will be recorded during the test period of 5000 hours. All records will be prepared in a way that can be printed. 2- The language of the program will be English 3- Program passwords will be given 4- There will be a computer infrastructure that will store at least 5 test data. 5- The processor will be i9, 32gb RAM Windows operating system will be used
General conditions	1- Training will be provided on the maintenance and use of the device 2- After the installation is completed, the device will operate without any problems for 1 month (4 weeks) for acceptance. 3- Electrical diagram and water pipe connection system diagrams will be provided 4- Maintenance manual will be provided 5- User manual will be provided 6- Parts in contact with salt fog and rain will be stainless 7- Electrical components will be suitable for 380V infrastructure 8- Warranty conditions will be specified 9- Spare parts will be provided for 10 years 10- Consumables list will be provided
