"Abnormal voltage" generally refers to a deviation from the expected or standard voltage level in an electrical system or device. The specific implications and consequences of abnormal voltage can vary depending on the context and the nature of the electrical system involved. In some cases, abnormal voltage can result from a fault or malfunction within the electrical infrastructure, such as a power surge or a voltage drop. This can lead to potential hazards, damage to equipment, or disruption of normal electrical operation. Abnormal voltage can also occur due to incorrect electrical connections, improper wiring, or faulty voltage regulation
