  1. DCH and the BRICK schema ontology

DCH BRICK Extensions

Classes

DCH has introduced some new classes in the Electrical systems modelling space.

Electrical_Utility_Meter

A meter between the electrical utility's grid and the customer's facility. Imported energy flows from the utility to facility. Parent Class(es): Electrical_Meter

Electrical_Generation_Meter

An electrical meter that is metering electrical generation (an Inverter). Parent Class(es): Electrical_Meter

Electrical_Storage_Meter

An electrical meter that is metering electrical storage (a Battery). Parent Class(es): Electrical_Meter

Site_Electrical_Meter

An electrical meter that is electrically closest to the utility point-of-connection, and which supplies a site and all of its buildings. Parent Class(es): Electrical_Meter

Solar_Inverter

A device that changes direct current from PV panel(s) into alternating current. Parent Class(es): Inverter

Battery_Inverter_Charger

A device that charges batteries or converts battery direct current into alternating current. Parent Class(es): Inverter

Hybrid_Inverter

A combined Solar_Inverter and Battery_Inverter_Charger. Parent Class(es): Solar_Inverter AND Battery_Inverter_Charger
