Mar 15, 2011 I am working in 2MW Photovoltanic Solar power plant as Electrical Engineer (O&M), these plant generate power at day time & take power (Import) at night. At night Import power is used for plant lighting only as generation stopped after sunset, At the time of Import power, we have a light load (near about 10KW), due to which our power factor is Low.

They often run wastefully, or at a reduced efficiency, for about 70% of their operating time, this being made up as follows: out of the concrete and left running 15% wrongly positioned in the concrete 35% vibrating already compacted concrete 20% Total: 70% This means that the poker is doing useful work for only 30% of the time, which is why it is so necessary to plan the compaction in advance, along with the placing method and technique, so that both operations are done as economically and as quickly as possible. Internal Vibrator Usage Internal vibrators are often used inefficiently. Vibrators These are mobile items of mechanical plant used to vibrate (shake) air out of fresh concrete. Concreting to the precast facade and then compact the concrete by Poker Vibrator to force out the air-bubbles trapped inside. Reshebnik po teoreticheskoj mehanike dievskij malisheva. There are 2 major types of vibrators: • External vibrators (Form vibrators) • Internal vibrators (Poker/Immersion vibrators) All types of vibrators have motors, which can be driven by: • Compressed air • Main supply electricity (230 or 400V & 50Hz) motors • High frequency electricity motors • Petrol or diesel (liquid fuel).
