In its most basic form the device consists of three parts.

Capacitive voltage transformer specification.

A typical application would be to utilize the cvts for power line carrier plc high frequency signal interface units. This section covers design manufacture assembly and testing at the manufacturer s works supply delivery at site of 420kv 220kv 132kv cvt complete with fittings and accessories. Sometimes a voltage transformer may have two or more than two secondary cores. The cvt is cheap and their performance is not much inferior to the highly insulated transformer.

They transform high voltage into standardised values for meters measuring and protection devices. The capacitive potential divider is used in combination with the auxiliary transformer and the inductive element. A capacitor voltage transformer cvt or ccvt is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal for metering or operating a protective relay. The capacitive voltage transformer consists of one condenser unit and one electromagnetic measuring unit emu.

For reducing the cost the capacitive potential transformer is used in the system. Voltage transformers type ecf are used in high voltage networks within the 72 550 kv range. Capacitive voltage transformer working. 1000kv capacitive voltage transformers 1000kv capacitive voltage transformers.

Products and services that increase power system reliability improve grid resiliency and responsiveness. As a global leader in grid infrastructure. One of the advantages the capacitive type has in comparison to the inductive type is the possibility to use capacitive voltage transformers as high frequency coupling units towards the primary system over headlines. For over a century utilities around the world have relied on ge to deliver.

Then these values are the sum of the output of all the secondary winding of a single voltage transformer. It includes current transformers voltage transformers and combis in oil gas and clean air insulation as well as special instrument transformers e g. Design of capacitor voltage transformers 87 7 1 general 87 7 2 external disturbances on capacitor voltage transformers 89 7 3 mechanical stress on capacitor voltage transformers 90 7 4 seismic properties of abb s capacitor voltage transformers 92 8. Capacitor voltage transformer cvt or capacitor coupled voltage transformer ccvt is a switchgear device used to convert high transmission class voltage into easily measurable values which are used for metering protection and control of high voltage systems.

Additionally a cvt ccvt used as coupling capacitors for coupling high frequency power line carrier signals to the transmission line. The trench group has a full portfolio of instrument transformers that is capable to meet any customer s needs worldwide and can be installed in any environmental condition.
