Medicaid is always the payor of last resort.
The principal offensive weapon was the boats torpedoes. Typically, the primary function was to take out enemy ships.
A current transformer pushes a ratio of primary current in the secondary. A potential transformer pushes a ratio of primary voltage in the secondary. Shorting a CT allows the full current the CT wants to push to flow. Shorting a PT makes it very difficult for the PT to produce rated voltage. To keep the voltage at rated value, the PT would have to push ~infinite secondary current.
Construction wise, in a live tank PT, both the primary & secondary windings will be placed on top tank. In a dead tank PT, primary & secondary windings will be placed in bottom tank.
A CT is used to measure current, and is NOT referenced to ground, and has very low primary impedance. A PT is used to measure voltage, is referenced to ground, and has a much higher impedance (since it is referenced to ground).
PT's are typically used for metering and relaying purposes to sample the power system voltage and phase angles. The primary is at line voltage, and the secondary is typically between 66 - 120 volts (depending on primary connection, Line to Line or Line to Neutral). So yes, PT's are step down transformers.

'CT' is used to designate current transformers, and 'PT' is used to designate potential transformers. A current transformer provides a ratio of primary current to the secondary. A potential transformer provides a ratio of primary voltage to the secondary. A power transformer (step up or step down) resembles a PT more than a CT.
