Since the example is fully related to the earthing of electrical apparatus only, therefore, there are two separately earth continuity conductor in whole factory (earth continuity conductors of other metalwork i.e. 1994) and further developed by Fu and Rich (2000, 2002). With out it your work is only an assembly of words. Find your Solar Hours per Day using the color-coding on this map. Explanation of each section is as follow: In this section, the biggest motor is 50hp, therefore, the central pair of earth continuity conductor should able to pass any value of fault current produce in the motor. Dear all, I designed a 10Kw,5Kw,3Kw system. – Examples in Imperial & Metric System, Oil Circuit Breaker (OCB) – Types, Construction, Working and Applications. Latitude and Longitude can be in deg/min/sec, or decimal degrees entered in Solar Photo‐Voltaic (PV) Power Plant Earthing Design Services In 2015 1.7GW of renewable energy capacity was added in Australia (46% of this was solar), while 1.3GW of coal based capacity was decommissioned. We depends on ad revenue to keep creating quality content for you to learn and enjoy for free.
