Ganieda opens up a new world of data to the Street Lighting Engineer
The PECU array used by your Meter Administrator holds a wealth of data. Ganieda allows you easy access to this data with built in reports and automated dialling.
The PECU Arrays contain 30 cells and records the lux level and event switching times for 28 events per channel (cell). While the switching event data is used by your Meter Administrator as the basis of your consumption figures, the full data can also be invaluable to Street Lighting Engineers.
By examining actual Lux levels against theoretical ones, the Engineer can monitor cell performance. Different cell types can be directly compared, even down to the manufacturer.
Built in reports furnish the Engineer with annual burning hours for each cell type, as well as identifying "rogue" cells which switch differently to the others of the same type in the array. Cell switching times and events are translated into simple language and tables of the half hour burning periods are stored for each day for each array. This enables an easy visual check on erratic cells.
Once annual burning hours are established, contracts tendering become more accurate as, armed with your latest inventory, a reasonable accurate "estimate" of your energy bill can be calculated on actual burning hours, not the manufacturer's theoretical ones.
Lighting authorities who are fortunate enough to own their own PECU array (such as Lancashire County Council) can test many types of cells using Ganieda, before using them "on the ground", as Ganieda can dial up and store data from multiple arrays.
