Same as above: key indicator of insulation and loading condition.
Solar arrays and inverters produce MV levels (0.6-35 kV). Step-up transformers raise voltage to transmission level and synchronize with utility grids.
一月 26, 2026 12:09 下午 回复至： Why is a dry type power transformer preferred for indoor facilities? #332032Dry type transformers eliminate oil, reducing fire risk and environmental containment requirements. They are used in buildings, tunnels, and industrial facilities where ventilation and fire regulations apply.
一月 26, 2026 10:36 上午 回复至： Why does a power station use a step up transformer for transmission? #332019Step-up transformers match generator voltages to the transmission network. Long-distance transmission at high voltage minimizes thermal losses and stabilizes grid power flow.
一月 26, 2026 12:35 上午 回复至： How are power transformer calculations performed for voltage and current? #331941Voltage and current calculations rely on turns ratio and load characteristics. Voltage follows Vp/Vs = Np/Ns, while current follows inverse ratio. Three-phase uses ?3 relationships for line quantities.
Using special configurations such as open-delta, Scott-T, or dedicated single-phase secondary windings fed from a 3-phase primary.
一月 25, 2026 7:21 上午 回复至： What is the output power of an ideal transformer according to theory? #331813Theoretical output power equals input power with no real losses, so P_out = P_in. Current increases as voltage decreases and vice versa, maintaining constant power transfer.
一月 23, 2026 9:56 下午 回复至： How do power transformers and distribution transformers differ in application? #331543Power transformers interface generation and transmission networks; distribution transformers supply end users. Power units prioritize full-load efficiency; distribution units must handle variable loading and regulation.
Major high-power transformer manufacturers include large global OEMs and regional heavy electrical companies capable of producing GSUs, HVDC converter transformers, and large autotransformers. These firms operate specialized plants with large core-handling, vacuum oil-processing, and high-voltage test facilities. They focus on 100 MVA and above, high or extra-high voltage ratings, and custom engineered-to-order designs for utilities, interconnectors, and generation projects across multiple continents.
一月 22, 2026 10:03 上午 回复至： Are CMM-12R oil regeneration systems suitable for other industrial oils? #331230Yes – while designed for transformer insulating oil, they can also treat turbine oil, hydraulic oil, FR3, Midel and other industrial fluids with similar degradation challenges.
Yes – remote control options are available, including smartphone or PC interfaces, allowing operators to monitor processes or adjust parameters off-site.
一月 22, 2026 3:47 上午 回复至： How does the oil level sensor in the TSS enhance operational safety? #331140The oil level sensor enables precise monitoring of the transformer’s oil height during processing. Operators can preset acceptable upper and lower limits. If oil deviates beyond preset thresholds – indicating possible leaks or pump issues – the TSS automatically closes valves and stops connected processing units to protect the transformer.
It confirms functionality, insulation quality, fault withstand capability, and correct tap settings before energization.
一月 21, 2026 2:04 下午 回复至： What are the environmental or operating condition requirements for an LFD device? #330936LFD does not require special ambient conditions, but it does need a controlled working environment to be effective and safe. The site must provide stable power for high current, good grounding, and protection from rain and dust. Ambient temperature mainly affects heat losses, not the process itself. More important are tightness of the tank, ability to maintain deep vacuum, and reliable temperature monitoring, because drying efficiency depends much more on vacuum quality and insulation heating control than on external climate.
HV design emphasizes dielectric strength, insulation clearances, impulse withstand, controlled gradients, low PD, and robust bushings.
Yes – USB-3 is suitable for sulfur polymer / sulfur-modified PMB, provided the unit is ordered/configured with the sulfur dosing (input) assembly and the recipe is run within the correct temperature window for your sulfur/polymer system. GlobeCore’s USB-3 is described as capable of implementing “virtually any bitumen modification process” using a wide range of modifiers and additives, and their configurator explicitly lists a Sulfur input assembly as an available option. Capacity depends on the USB-3 version, but typical industrial configurations are in the 8-12 m³/h range (and higher on other variants), while sulfur addition is treated as an additive stream inside the standard continuous process.
Dry-type transformers avoid liquid dielectrics, reducing fire and environmental risk indoors. They are preferred in buildings, tunnels, offshore modules, and industrial spaces where spill containment, ventilation for oil-filled units, or fire barriers would be problematic. Resin or cast-coil insulation tolerates moisture and contamination better in some environments. They also reduce maintenance related to oil sampling and leaks, making them attractive for commercial and institutional facilities.
一月 20, 2026 12:10 下午 回复至： What roles do electrical power distribution transformers play in utility networks? #330544Distribution transformers convert MV feeders to LV service voltages for residential, commercial, and light industrial loads.
Designers consider electrical ratings (kVA, voltage, frequency), cooling class, insulation level, losses, impedance, vector group, short-circuit withstand, thermal limits, materials, and standards. Mechanical constraints, transport dimensions, and service environment also shape the final design.
Consumption includes no-load losses (core losses measured at rated voltage) and load losses (copper and stray losses measured at rated current). Utilities meter or estimate losses for lifecycle cost analysis.
