Problems solved by technology

However, this approach method may cause frequent or long-term overvoltage or undervoltage conditions that are so small that they go undetected for long periods of time, eventually resulting in damage to the surge protection device or connected equipment.

Abstract

A supply voltage monitor includes a switch circuit that enables coupling of an AC power supply to a load. A control circuit switches the switch circuit from a non-conductive state to a conductive state, and vice-versa, based upon a state of a state machine implemented by the control circuit. The control circuit further reports anomalies in process variables, such as voltage and current levels, temperature, etc., based on the state of the state machine. The transition criteria of the state machine, i.e., the criteria that is met to compel a transition in state, is selectable by a user by way of a user interface. The transition criteria may correspond to different power levels that define a range over which the power is considered nominal and a range over which the power is considered to be an anomaly. The transition criteria additionally define what type of anomalies are reported without a change in the conductivity of the switch circuit.

Description

technical field [0001] The invention relates to a power supply protection technology, in particular to a power monitoring and remote monitoring device and a monitoring method thereof. Background technique [0002] Many existing power protection devices, such as surge protective devices (SPDs) and hybrid filters, incorporate an automatic switching circuit capable of disconnecting the output to the device in response to various supply wiring faults and / or overvoltage or undervoltage conditions AC power, here refers to abnormal power. Circuitry that detects overvoltage or brownout conditions needs to reach the rated line voltage before AC power flows through the device output and connections. Line voltage conditions, such as surges and overvoltages, can cause the failure of certain power protection devices, such as metal oxide varistors and other suppression components. Additionally, some equipment power supply units may be damaged during surge or sustained overvoltage condit...
