Photovoltaic power plant series and types

In cooperation with the daibau.sk portal, we have prepared an article in which we try to advise customers what to look out for. The full article can be found at this address: daibau.sk 1. What are photovoltaic power plants and what types are there, what does your company offer when it comes to photovoltaics? Photovoltaics in Slovakia are mainly divided according to their power output into small sources up to 10.8 kW, which are mainly intended for households and are also supported by the subsidy system Green Households. For companies and commercial entities a local source is used, this is from 10.8 to MRK. The latter is further subdivided without dispatchable control (up to 100 kW) and with dispatchable control (above 100 kW). PV is a great resource, but it needs to be properly designed. In particular, the design needs to take into account the consumption of the customer site and design it in such a way that its production also replicates consumption. In that case, it also has a very fast financial payback. Our company realizes all...

Service and maintenance of substations

Inspection and maintenance of the substation - what is to be done in the inspection and maintenance of the high voltage substation? If your company or business has a transformer station on its property, it is imperative that it is looked after and it is important that all the necessary inspection and maintenance work is carried out to ensure that it is working properly. Our company places a high value on comprehensive maintenance and inspection of all equipment to determine the exact condition and prevent breakdowns. Essential activities include: - inspection of the transformer - checking for leaks, insulators, temperature and correct setting of fuse values; - inspection of HV distribution - checking HV switchgear, accessories, fuses, section switch and other components; - inspection of LV distribution - checking low voltage switchgear, fusing, junction temperature; - checking earthing; - checking safety warnings and warning signs; - checking documentation; - checking Local Operating Regulations; - many other activities to verify the condition of the substation.

Measurement of insulation properties of electrophoretic painting bath

Measurement of insulating properties of electrophoretic paint tubs Performance of specialized measurement, inspection and revision of paint tubs of car bodies. It is used to determine the condition of the surface properties. It is carried out using two measurement methods, it is mainly carried out in the automotive industry. Measurements and revisions of paint and paint application areas are carried out, while all safety conditions with regard to the environment and explosive atmosphere must be observed. During the inspection and testing, the paint bath must be drained, dried and all elements of the anodic-cathodic technology switched off. Measurements aimed at detecting malfunctions in the envelope, leakage currents and the properties of physical variables, while checking the paint bath, its properties and the overall safety of the area. The inspection is carried out during the shutdown period and all emulsion and paint must be drained. How does painting work ? Until recently, the protection of uncoated steel panels has been entirely dependent on pre-cleaning and subsequent painting of the layers. However, even with a zinc coating, the effect of the paint is insufficient because...
