  • Apparent Power (VA): The combination of real and reactive power.
• Kipengele cha Nguvu (PF): The ratio of real power to apparent power, indicating the efficiency of power usage.
• Matumizi ya Nishati (kWh): The total amount of electrical energy consumed over a period of time.
• Frequency (Hz): The rate at which the alternating current (AC) changes direction.
• Harmonics: Distortions in the voltage and current waveforms, which can cause problems for sensitive equipment.
• Voltage Sags and Swells: Short-term decreases or increases in voltage, which can disrupt equipment operation.
• Transients: Very short-duration voltage spikes, which can damage electronic components.
• Demand (kW or kVA) The maximum power drawn during a specified period.

4. Types of Circuit Monitors
