An automatic isolation switch (AIS) system is provided for controlling a supply of electrical power to a load. The system includes a switch and a controller. The switch is connected between a first power system and the load and between the first power system and a second power system. The first power system includes a grid, and the second power system includes a power source and an inverter coupled to the power source. The controller is configured to detect an adverse power condition on the first power system for supplying electrical power to the load; to isolate, via at least one switch, the first power system from the load and the second power system, in response to the detecting of the adverse power condition; and to activate the inverter of the second power system to supply electrical power from the second power system to the load.

Automatic isolation switch for a microgrid

Systems and methods for providing a mobile memory module in an automatic transfer switch (ATS) allow the memory module to be easily removed from a controller of the ATS. The mobile memory module is a discrete, nonvolatile memory module that stores operational settings for the ATS and can be mounted and removed via a removable fastener. When thus mounted, the mobile memory module is connected to a signal path that allows data communication with a microprocessor on the controller. The microprocessor can retrieve operational settings from the mobile memory module as needed and store updated or new operational settings on the mobile memory module as required. In some embodiments, the mobile memory module has a protective outer housing that is hardened to withstand catastrophic transfer switch failure while still retaining all operational settings stored on the module.

Mobile memory module for electrical transfer switch

In an example, a control system for controlling a generator and providing an alarm upon detection of a fault condition. The control system includes a control relay, which includes a normally-open (NO) contact pair and a normally-closed (NC) contact pair, between the transfer switch and a controller. The NO contact pair is provided by a NO contact and a common contact, and the NC contact pair is provided by a NC contact and the common contact. The controller can receive signals indicative of a state of the contact pairs of the control relay and, based on the signals, determine whether to activate the generator and/or activate an alarm system.

Systems and methods for controlling a generator

Methods and systems for control of a power-quality measuring or monitoring device, such as a transfer switch, are provided. An example method includes a transfer-switch controller of a transfer switch receiving an input command from a user. The method further includes, in response to receiving the input command, the transfer-switch controller entering a safe state, wherein in the safe state operational settings of the transfer switch remain unchanged. Still further, the method includes, after entering the safe state, the transfer-switch controller providing, based on operational data specific to the transfer switch, information regarding a feature of the transfer switch.

Methods and systems for power management control

A method and system are provided for transferring a load between a primary power source and a secondary power source. In accordance with the disclosure, a controller senses, via a sensor, an electrical signal providing power from the primary power source to the load. The controller also detects a non-conforming power event by determining that a parameter of the electrical signal is either more or less than a first threshold value. Responsive to the detection of the non-conforming power event, the controller determines a quantity of non-conforming power events that occur during a first time interval. The controller further can compares the determined quantity of non-conforming power events to a second threshold value. Responsive to the determined quantity of non-conforming power events being either greater or lesser than the second threshold value, the controller initiates a control signal, such as a control signal to initiate a load transfer.

Method of identifying when to initiate control sequences

A method and system are provided for controlling transfer switch operations in a power distribution system. The method and system involve monitoring an electrical parameter of an electrical signal from a first power source associated with supplying power to a load; determining whether the electrical parameter satisfies a parameter threshold; selecting to increment or decrement a count value in accordance with the determination; and responsive to determining that the count value satisfies a first count threshold, initiating a start signal to start operation of a second power source to supply power to the load. The electrical parameter can be voltage or frequency, or other parameter(s) from which a power quality of the electrical signal may be evaluated. The electrical signal can be a single or polyphase electrical signal.

Proactive engine start (PES)

An automatic autonomous redundant switch configured for providing energy from either a first power source or a second power source to a load is provided. The automatic switch includes a first automatic transfer switch (ATS) and a second ATS. The automatic switch further includes an interconnecting bus configured to connect the first ATS and the second ATS, and at least one controller configured to control the operation of the first ATS and the second ATS. Still further, the first ATS and the second ATS each include a respective transfer-switch mechanism, a respective bus attachment configured to connect to the interconnecting bus, and a respective motorized rack-out mechanism having a powered actuator.
