Explain the main causes of electrical system failure if maintenance is not carried out regularly!, Too high a voltage makes all components work harder so that the equipment's lifespan is longer and the system is more stable in the long term., Loose cable connections and reduced insulation cause increased resistance, excessive heat generation, and ultimately trigger system damage or even fire., An electrical load that is too low causes the system to not work optimally, causing continuous protection trips., Reducing the network frequency actually makes the equipment last longer because the electricity works slower., Explain the impact of a decrease in cable insulation resistance below standard!, Power consumption is smaller so that electricity use is more efficient and safer for equipment., The voltage becomes stable because the flow of electricity becomes more controlled on its path., The risk of current leakage increases, making it very possible for short circuits, electric shocks and fires to occur., Equipment performance increases because the resistance in the cable becomes smaller., Explain the most appropriate conditions that indicate the need for predictive maintenance!, The machine has just been installed so it doesn't need any inspections anytime soon., A total blackout occurs caused by external factors such as interference from the generator., The

directly., To detect hot spots which are an early indication of damage or fire., To determine the power factor value in an electric power system., Explain the biggest risks resulting from a poor grounding system!, The electric current becomes so small that the equipment cannot work optimally., The equipment's lifespan is longer because there is no leakage current., The risk of electric shock and fire increases because the leakage current is not properly channeled to the ground., The circuit breaker (MCB) will work more lightly and trip less frequently., Explain the consequences if preventive maintenance is not implemented for a long time!, The electrical system will be more stable because it is not touched often., The risk of sudden damage increases and can suddenly stop operations., The electrical voltage becomes more constant throughout the installation., Each device will be able to repair its own faults., Explain the devices that must be prioritized in electrical maintenance!, A regular power outlet that is only used for light equipment., Room lighting that does not affect the main system., Distribution transformer because it is the main center for distributing electrical energy throughout the system., A wall switch that only functions as a simple breaker., Explain the consequences of loose cable connections!, Reduce reactive power so that the system becomes more stable., Lowering the temperature of the conductor due to reduced electric current., Increases local resistance which causes overheating and potentially causes fire., Improve the power factor thereby saving energy., Explain what is not a benefit of electrical maintenance!, Reduce the possibility of fire due to short circuits., Reduce downtime so that productivity is maintained., Increases the load and accelerates damage to the electrical system., Increase the efficiency of electrical energy use., Explain the safest method before carrying out electrical maintenance!, Replace the cable immediately so the job can be completed more quickly., Using gloves only without additional procedures., Implement a Lock Out – Tag Out (LOTO) system to ensure that there is no active electrical current., Work together to get the job done quickly., Explain the early signs of overload in the electrical system!, MCB frequently trips, a burning smell appears, and the temperature of the cable or panel increases abnormally, indicating that the current exceeds capacity., The light is brighter than usual, indicating that the system is stronger., The machine runs faster and lighter without any signs of interference., The voltage becomes very stable because the load is distributed evenly., Explain the long-term impact if the electrical system is rarely maintained!, Efficiency will increase as the system gets used to working independently., Operating and repair costs increase as minor damage develops into major damage., Voltage and current become ideal naturally., The equipment's lifespan becomes longer without interruption., Explain the main function of the testing tool called a Megger!, Used to measure the magnitude of electric current in a circuit., Used to determine the amount of active and reactive power of a load., Used to measure the insulation resistance of cables or electrical equipment to determine the suitability of the insulation condition., Used to regulate the size of the output voltage., Explain the types of maintenance carried out based on the time or working hours of the equipment!, Breakdown Maintenance, which is maintenance after serious damage occurs., Preventive Maintenance, namely scheduled maintenance carried out before damage occurs., Predictive Maintenance, namely maintenance based on technician intuition., Emergency Maintenance, namely maintenance when a natural disaster occurs., Explain the most appropriate action when the electrical panel feels hot but there is no damage yet!, Ignore it because there is no visible damage yet., Wait until the panel is completely damaged before repairing it., Perform predictive maintenance such as temperature measurements and connection checks to prevent damage., Shutting down the entire system without performing any checks., Explain the signs of a decline in electrical system performance!, The power factor increases and the power consumption decreases drastically., The temperature is always stable in all parts of the system., Efficiency decreases, equipment trips frequently, and performance becomes unstable., The voltage is always at the ideal value without fluctuation., Explain the main priorities that must be considered in electrical maintenance!, The beauty of the arrangement of cables and panels to make them look neat., Human and environmental safety are the most important aspects of any electrical work., Finishing work as quickly as possible without paying attention to procedures., Reduce costs by using existing tools., Explain the consequences of installations or systems that rarely receive maintenance!, The system becomes more resistant to disturbances because it is rarely touched., Sudden breakdowns occur more frequently because minor problems are not detected early on., Temperature and current are always in ideal conditions., The risk of accidents becomes smaller., Explain the main function of the electrical logbook!, Used only as an administrative archive without technical functions., Used to embellish technician reports., Used as evaluation data, disturbance analysis, and a basis for planning subsequent maintenance., Used to reduce the current in equipment., Explain the most appropriate conclusion regarding the importance of electrical maintenance!, Electrical maintenance is an additional activity that is not so important., Maintenance only needs to be carried out after total damage occurs., Electrical maintenance is a very vital activity to maintain the safety, reliability and sustainability of the electrical system., Maintenance is only required in large-scale companies or industries., Explain the signs of a decline in electrical system performance!, The power factor increases and the power consumption decreases drastically., The temperature is always stable in all parts of the system., Efficiency decreases, equipment trips frequently, and performance becomes unstable., The voltage is always at the ideal value without fluctuation..
