Abstract
Abstract A diagram or display board for electrical power networks, comprising indicator modules, in the form of boxlike enclosures containing illuminating lamps and having removable indicator plates on the front, which modules are each mounted on the front of a perforated support panel by two bolts, one insulated and conducting electrical power to the lamps, and the other connected to the panel which acts as common or ground. A nonglare surface is produced on the indicator plates which may be fitted with clips for attachment to the boxes or slidably held therein. The plates and the lamps may be of different colors to distinguish between the various components and temporary changes in system conditions are indicated by flashing the lamps at different frequencies in accordance with the urgency of the attention required. The board is controlled both manually and by computer and the intensity of illumination may be varied for color balance or to adjust to ambient lighting.
