Many household appliances can be operated in standby mode favoring to its benefit displaying the setting information and allowing them to switch on quickly. On Frequency range 9-150 kHz, standby mode operation of some household appliances particularly equipped by EMC filter have a very low impedance which can deliver any path for intentional and unintentional signals in that frequency range. This condition can influence the voltage and current disturbance on the network and need to be further observed. The study focused on identifying the equivalent circuit parameter of standby mode operation for particular household appliances. The equivalent circuit is useful to simulate and predict the behavior of voltage and current disturbance occurred in the low voltage distribution network when standby mode appliances are connected. The appliances under test chosen are inverter based microwave, conventional microwave, and induction stove. Based on the measurement, it can be noticed that for standby mode operation, the impedance of particular appliance has series and parallel resonance properties on specific frequency causing very low impedance at certain frequency in the range of 9-150 kHz.
