Instrument transformers are intended to supply measuring instruments, metres, relays, etc., with a current or voltage proportional to the values in the line.
Current Transformers are designed to produce a scaled down replica of the current in the power line and isolate the measuring instruments, meters, relays, etc. from the high voltage power circuit.
Current Transformers are designed to produce a scaled down replica of the current in the power line and isolate the measuring instruments, meters, relays, etc. from the high voltage power circuit.
Arteche combined transformers are designed for outdoor service and comprise a current transformer and an inductive potential transformer.
Capacitor Voltage Transformers isolate the measuring instruments, meter, relays, protections, etc., from the high voltage power circuit and produce a scaled replica of the current, with the possibility of transmitting high frequency signals through the high voltage power lines. Coupling Capacitors are used for coupling high frequency communication signals and correspond to the capacitive part of a capacitive voltage transformer.
Combine measuring transformers are units for outdoor service containing a current transformer and an inductive voltage transformer. Their application is therefore the same as that of the components it is made up of. They are for use in work where for space or cost reasons, independent equipment is not allowed.
Coupling Capacitors are used for coupling high frequency carrier signals and correspond to the capacitive part of a capacitive voltage transformer.
Line Traps direct the carrier signal to the appropriate lines, blocking the transmission to the rest, and thus avoiding loss of the carrier signal power and interferences.
Dry Insulation Transformers are designed to produce a scaled down replica of the current in the power line and isolate the measuring instruments, meters, relays, etc. from the high voltage power circuit.
These Voltage Transformers supply a low voltage power output (up to 330 kVA) directly from the high voltage line. The power output can feed the substation’s auxiliary services or other installations (telecommunication antenna, small scale rural distribution,..)
