Ultra-low frequency dielectric strength testing is another method of power frequency withstand voltage testing, because large-capacity testing is required, and large-scale equipment is not only expensive, but also bulky. The power department did some tests to solve these problems. According to domestic and foreign tests, this product can solve this problem. Not only the size of the instrument is small, but the weight is greatly reduced.
Precautions
When carrying out 35KV cable test, one-phase test is strongly suggested. Voltage is set to 60KV (General Requirements)-78KV (according to the rules needed) and the frequency is set to 0.1Hz, 0.05Hz,0.02Hz and 0.01Hz. The manual said load capacity is the theoretical value, the scene 35KV cable length can reach 3-15 km.
In case the cable is too short(less than 500 meters), the capacitance of the test object is smaller than 0.1 F and the pressure cannot be normally boosted, please connect 0.1 F high-voltage capacitance in parallel way.
Keep high-voltage terminals nylon spin by the above numbers to the corresponding nylon seat, high-voltage lines to ensure good contact , no contact is good , it will cause a discharge , burned the high side . When nylon terminals tightened, pay attention to the intensity, excessive tightening may damage the nylon terminals.
NCS-BP105 Fieldbus Power Conditioner
NCS-BP105 Fieldbus Power Conditioner applies to Foundation Fieldbus and Profibus PA control system and provides power to fieldbus instrument. Fieldbus Power Conditioner adopt an active impedance control circuitï¼?prevents the conventional power supply from absorbing the Fieldbus signal otherwise interfering with the operation of the Fieldbus. Working with terminator together, it provides perfect bus signals. There are two LED for power indication and fault indication. Fieldbus Power Conditioner can support redundancy when two Power Conditioners work in redundancy mode in order to enhance the reliability of the system.
