Block-Type CT; The current transformers of the new RITZ-RBLCT 1224 have been specially developed for use in the switchgear and power supply market. They can be used for measuring and protection purposes with a rated current of max. 1500 A, Ith.:100 x In, max. 25 kA/1 sec. in the voltage
Medium Voltage Instrument Transformers. Instrument Transformers are transformers which convert high currents or voltages into measurable and standardized currents or voltages. These are then proportional and in-phased to the primary signal. They are intended to supply electrical measuring instruments, meters, relays or other electrical devices.
Sep 26, 2013 · Fuse manufacturer Littelfuse states in its literature that “The terms ‘medium voltage’ and ‘high voltage’ have been used interchangeably by many people to describe fuses operating above 600 V.” Technically speaking, “medium voltage” fuses are those intended for the voltage range of
Sep 26, 2013 · Medium-voltage electrical system protection Overcurrent protection is required for medium-voltage transformers, and connecting these transformers is common for medium-voltage distribution systems. By Leslie Fernandez, PE, LEED AP, JBA Consulting Engineers, Las Vegas September 26, 2013
maintenance for current and voltage transformers 1. Service conditions The transformers should be mounted in dry indoor conditions where the ambient air is not signifi-cantly polluted by dust, smoke, corrosive gases, vapours or salt. The transformers are designed for standard ambi - ent temperature between –5°C and +40°C. The al-
