480 v, or 600 v) or medium-voltage (2.4 kv or 4.16 kv) secondaries. The function of a transformer primary-side protective device is, in general, to provide system protection as well as transformer protection.
RBLCT12 17,5 24 Support-Type current transformers narrow design according to DIN 42600, part 8. 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.

Transformer Protection Application Guide This guide focuses primarily on application of protective relays for the protection of power transformers, with an emphasis on the most prevalent protection schemes and transformers. Principles are emphasized. Setting procedures are only discussed in a general nature in the material to follow.
b. Circuit breaker size or fuse rating up to 250% of transformer-rated current, for transformers with secondary voltage 1,000V or less. For transformers with primary voltage 1,000V or less and current of 9A or more, with primary protection not more than 125% of transformer-rated current, the “next-size-up” rule can be applied [Table 450.3(B)].

Flex-Core® maintains a large in-stock inventory of Potential Transformers including Low Voltage and Meduim Voltage Potential Transformers for most common applications.. Below is a list of all potential transformers available through Flex-Core, however, not all models are in-stock.
Eaton’s Cooper Power series Bay-O-Net fuse offers a protection package for single- and three-phase transformers. The assembly combines the ease of hotstick operation with the safety of deadfront construction and is used with an isolation link to prevent line personnel from closing into a fault when replacing a blown Bay-O-Net link. Eaton’s Cooper Power series MagneX Interrupter is an
Equipment Protection The requirements of 450.3 cover only transformer protection. In practice, other Inrush Current = 12 x 0.333 = 4A Since the voltage is 2400 volts we can use either a JCW-1E or JCD-1 E. B. Using the rule of thumb–300% of 0.333A is 0.999A.
