ELECTROSTATIC FIELDS AND FIELD STRESS CONTROL In response to an increasing demand for electrical energy, operating trans­mission level voltages have increased considerably over the last decades. Designers are therefore forced to reduce the size and weight of electrical equipment in order to remain competitive. This, in turn, is possible only through a thorough understanding of the properties of insulating materials and knowledge of electric fields and methods of controlling electric stress. This chapter is therefore devoted to a discussion of some of the problems encountered when analysing even relatively simple but practical insulating systems. Teaching experience has shown that this is a necessary prerequi­site in order to gain a clearer understanding of the behaviour of insulating materials. However, no attempt will be made here to introduce the basic field equations, or to treat systematically the numerous methods available for calcu­lating electrostatic fields as this may be found in many books.(1-4)* Rather,...

REFRIG & AIR CONDITIONING Refrigeration Refrigeration is the process required for safe storage of food or any other product to be transported, which necessitates that it is maintained at low temperatures. Whatever be the size of the process, it will have a cooling unit (evaporator), a refrigerant compressor and a condenser. The refrigerant used is generally Freon-12 or Freon-22 but ammonia is also used in large systems. Basic refrigerant circuit of A direct (Primary) expansion system used for cooling of meat and vegetables Domestic Refrigerator Air Conditioning The air must be delivered to the area to be air-conditioned at a definite temp. and specified relative humidity. Power equipment comprises of Motors for compressor, fans and SW cooling pumps. Control equipment include                                                          Electrical solenoid valves High/low pressure switches Temperature switches Cut-outs for i.      Overcurrent cut-outs ii.      loss of refrigerant iii.      low compressor oil pressure etc. Air conditioning Scheme- Main Components Electrical...

Freeboard The distance between the top of the hull and the waterline. As the ship is loaded, it sinks deeper into the water so the freeboard is reduced. The positioning of the load line mark is aimed at ensuring the freeboard is the minimum necessary for the safety of the ship.   p/p = length between perpendiculars w/l = length at waterline o/a = length overall b = beam f = freeboard d = draught (draft) freeboard  means the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. In commercial vessels, the latter criteria measured relative to the Ship's load line, regardless of deck arrangements is the mandated and regulated meaning.In yachts, a low freeboard is often found on racing boats, for weight reduction and therefore increased speed. A higher freeboard will give more room in...

ENGINE ROTATION Marine engine rotation considers Left Hand (LH) to be the standard while Right hand (RH) is considered "Opposite" rotation. You should ALWAYS view the rotation while standing behind the product looking at the flywheel. Although this sounds funny on the surface, anything short of this will confuse the issue and therefore this is a very important issue to follow. A LH engine spins CCW (Standard Rotation)   A RH engine spins CW  (Opposite Rotation)   IMPORTANT: It is extremely important to note that engine and propeller rotation are not one and the same. In most cases the propeller rotation will differ from the engine rotation due to the gearing. A few of the older, "Iron-Body" transmissions with specific ratios would turn either direction.  But, in general, when standing at the back of the boat looking forward, with a single STD Rotation (LH/CCW) engine, most of the transmissions turned CW...
