Trench-high-voltage-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 .... Oil-insulated combined instrument transformers are used to convert high transmission line voltages and currents (voltage up to 145kv and current up to 5000 a) to standardized low and easily measurable values, which are used for metering, protection and control of the high voltage system. as such, the need for accurate and reliable voltage and current transformation is essential. the ..., oil-insulated voltage transformers are used to convert high transmission line voltages (up to 550kv) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system..

Trench, a siemens company - the global leader for high voltage instrument transformers up to 1200 kv: over 100 years of proven reliability and innovation. complete product portfolio for ais & gis ..., siemens will equip a 145-kilovolt (kv) substation owned by e.on sweden with sf6-free high-voltage products by the middle of 2020. the orders comprise six bays, including circuit breakers for 72.5-kv and 145-kv from siemens as well as 145-kv instrument transformers from trench..

Power voltage transformers (power vts) combine the attributes of an inductive voltage transformer with the application of a small power transformer. therefore, they are the perfect solution wherever low voltage is needed and high voltage is available. power vts only have to be connected to the high voltage overhead line to provide power at low voltage. due to this direct connection to the ..., capacitor voltage transformer cpb (72-800 kv) world-class cvt for long term performance and reliability. capacitor voltage transformer cpb is designed for revenue metering and protection in high voltage networks. it is of single-phase design and intended for connection between phase and ground in networks with insulated or direct-grounded neutral points. the high quality, state of the art ....
