High Voltage Current Transformers
Arteche
The Arteche CA series is a range of current transformers up to 800 kV, based on inverted-type oil-impregnated paper insulation technology.
It is characterised by very high precision, stable throughout the equipment's lifetime (up to 0.1%), high reliability, a wide range of primary currents from 1 to 5,000 A, and a short-circuit current withstand of up to 120 kA/1 s.
The CA series covers a wide range of applications, including very low or very high currents, as well as environments subject to extreme temperatures.
High-voltage measurement transformers
Measurement transformers convert HV line currents and voltages into values that can be measured by meters and protection devices.
ARTECHE offers a wide range covering all our clients' needs. Current, voltage and combined transformers, with oil-paper or gas insulation up to 800 kV.
High-voltage current transformers
Current transformers are designed to reduce current to manageable values proportional to the original primary currents. They isolate measuring instruments, meters, relays, etc. from the high-voltage circuit. Some of their characteristics:
- Current input to various types of protection relays.
- Ideal for installation at measurement points thanks to their very high precision.
- Excellent frequency response, suitable for waveform quality monitoring and harmonic measurement.
- Suitable for installation on AC filters in converter substations for HVDC projects.
High-voltage inductive transformers
Inductive voltage transformers are designed to bring voltages down to manageable values proportional to the original primary voltages, isolating measuring instruments, meters, relays, etc. from the high-voltage circuit. Some of their characteristics:
- Voltage input for various types of protection relays.
- Ideal for installation at measurement points thanks to their high level of precision.
- Suitable for high-voltage line discharge and capacitor banks.
