Technical specification for 33 11kv power transformers apdrp scheme page 2 of 72 iec 606 application guide for power transformers. Some definitions and requirements of these standards such as csa c88 m90 ieee c57 12 00 and iec 60076 are different.

Doc 462 kb 4 1 2016. The voltage transformer must be suited to requirements relating to protection and. In its most basic form the device consists of three parts. Hitachi abb power grids is a major transformer manufacturer throughout the world and offers both liquid filled and dry type transformers as well as services for complete life cycle support including replacement parts and components.

The secondary voltage is substantially proportional to the primary voltage and differs from it in phase by an angle that is approximately zero. Find voltage and potential transformers on globalspec by specifications. Medium voltage transformers provide value and reliability with a variety of options to increase system protection and environmental responsibility. Depending on their design voltage transformers will be connected either.

The following have different explanations in these standards. Some transformer winding primary usually high voltage connecting wires are of many types. May be labeled as h 1 h 2 sometimes h 0 if it is internally designed to be grounded and x 1 x2 and sometimes an x 3 tap may be present. This list is not to be considered exhaustive and reference to a particular standard or.

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.
