This utility model provides an electromagnetic isolation circuit and an electrical energy measurement device, relating to the technical field of electronic circuits. It includes: a filtering module, an isolation transformer drive module, an EMI suppression module, a transformer module, a rectifier module, and a voltage regulator module. The filtering module filters a first power supply. The isolation transformer drive module generates a primary-side power supply based on the filtered first power supply, which is then input to the transformer module. The EMI suppression module suppresses common-mode interference on the primary-side power supply. The transformer module converts the suppressed primary-side power supply into a secondary-side power supply with a preset ratio. The rectifier module rectifies the secondary-side power supply to obtain a rectified power supply. The voltage regulator module regulates the rectified power supply to obtain a second power supply, which powers the load. This invention solves the technical problem of instability in isolation circuits under strong magnetic environments, achieving high stability and safety.
