EFFECTIVE USE OF MONITORING EQUIPEMENT 2Safety monitoring equipment is the equipment that is applied in the prevention ofthe power generating systems from faults. These protective devices have componentswhich include the current and voltage transformers to reduce the amount of voltageand the currents of the systems generating electric power for a convenient function ofthe relays (Bentarzi. 2014). Another component is the protective relays which act as asensor of the fault and also initiates a trip and helps in disconnection. There are alsocircuit breakers for closing or opening the systems based on relays automatically(Meier 2013). There are also batteries which help in the provision of power wheneverthere is power disconnection within the systems. These safety monitoring equipmentinclude Transformers and circuit breakers.TRANSFORMERSInstrument transformers help in creating isolations of electrical current from thepower system and this helps in the establishment of a safer ground for the techniciansoperating the relays (Frank, 2013). Transformers also help in accurate reproduction ofpower system voltages and currents over large operating ranges. Excessive voltage.Transformers prevent excessive voltage transmission hence providing protectionto the plant and the public including the workers within the plant. It does this bydisconnecting the devices which experience an overload. Transformers and otheritems in small stations may need more protectors based on temperature or pressure ofgasses.

EFFECTIVE USE OF MONITORING EQUIPEMENT 3Phase voltage overload. Overload protection requires a current transformer which simply measures the currentin a circuit. There are two types of voltage overload protection. These are Instantaneous overcurrent which requires that the currents exceed a predetermined level for the circuit breaker to operate and Time overcurrent (TOC) that functions according to the curve of current versus time. According to this curve, if the current determined become above a specific limit forthe amount of time available, the circuit breaker or fuse will operate.CIRCUIT BREAKERSA circuit breaker normally breaks off the flow of current subsequent to a defectbeing realized. The circuit breakers can always be replaced manually or automaticallydistinct from a fuse that works only once and must be replaced (Hou,2012).Excessive voltage During cases of excessive voltage the transmission of electric power is managed and given protection using high voltage current breakers.Phase voltage overload. Circuit breakers are instrumental in avoiding electrical overload because they are made to trip, halting current from flowing to the overloaded phase of the building. This means for instance, that if a 15-ampere would trip whenever current surpasses 15-ampere.When the circuit breaker trips, it is an indication that there are several gadgets plugged in that circuit or some device that is malfunctioned (Russell, 2013). Itis therefore advised that the problem is located and corrected before resetting a circuit
