HOME PRODUCTS DIGITALIZATION SUSTAINABILITY ABOUT US NEWS CONTACT Search INSTRUMENT TRANSFORMERS Electrical instrument transformers transform high currents and voltages to standardized low and easily measurable values that are isolated from the high voltage. When used for metering purposes, instrument transformers provide voltage or current signals that are very accurate representations of the transmission line values in both magnitude and phase. These signals allow accurate determination of revenue billing. When used for protection purposes, the instrument transformer outputs must accurately represent the transmission line values during both steady-state and transient conditions. These critical signals provide the basis for circuit-breaker operation under fault conditions, and as such are fundamental to network reliability and security. Instrument transformers used for network control supply important information for determining the state of the operating conditions of the network. Instrument transformers technology can also empower the grid with auxiliary power supply and highly precise power quality measurements. Please browse our instrument transformers brochure here.
