![]() Line-to-line voltages in three phase systems are typically 1.732 times the phase-to-neutral voltages:.Ultra-High Voltage: equal to or greater than 1000 kV.Extra-High Voltage: greater than 230 kV but less than 1000 kV. ![]() High Voltage: greater than 100 kV and equal to or less than 230 kV.Medium Voltage: greater than 1000 volts and less than 100 kV.Delta connected systems typically do not have a neutral.Number of wires: 2, 3, or 4 (not counting the safety ground).Number of phases: single or three phase.Classification of Electrical ServicesĪlternating current electric power distribution systems can be classified by the following properties: Meters and current transformers are designed for use on either 50 or 60 Hz systems. The new WattNode Wide-Range Modbus covers 100-600 Vac, wye and delta, single-phase and three-phase with a single model. WattNode ® meter models are available in seven different versions that cover the full range of electrical services types and voltages. The nominal system supply voltages listed below can vary by ☑0% or more. This page describes various types of utility electrical services and supply voltages.
