What is the voltage between any two hot lines of a 230-volt delta power supply?

In a three-phase delta power supply, the voltage between any two hot lines is indeed equal to the line-to-line voltage. For a system that is specified as a 230-volt delta supply, the voltage measured between any two hot lines will be 230 volts. This is because in a delta configuration, the voltage is distributed across the phases such that each hot line is at a different phase angle, leading to this direct measurement.

The line-to-line voltage in a delta system is consistent with its rated voltage, which in this case is 230 volts. Understanding this concept is crucial when working with three-phase power systems, as it helps technicians manage power distribution effectively and ensures that equipment is operated within its specified voltage ratings.

In systems where voltages like 240V or 208V are mentioned, those are common in specific applications or configurations, but they do not apply in this situation where the supply is specifically rated as 230V.
