standard defines the standard voltage values used for electrical supply systems and equipment design globally. It serves as the primary reference for ensuring compatibility between the power grid and electrical devices. IEC Webstore Core Voltage Classifications iec 60038 standard voltages pdf 103

When a client from a different country orders an MV switchgear panel, they will reference IEC 60038 to confirm the rated insulation voltage (e.g., 12kV, 24kV, 36kV). Introduction

This category covers residential, commercial, and light industrial utilization. Medium Voltage (MV) AC Systems (Above 1 kV to 35 kV): Standard nominal values include A recent amendment (2021) added to the preferential values in Table 3. High and Extra-High Voltage Systems (Above 35 kV): Covers transmission grids with nominal voltages such as , and up to ultra-high voltages. The highest equipment voltage was recently increased from 1,050 kV to 1,100 kV for the most advanced systems. Traction Systems (AC and DC): Defines standards for railways, including DC voltages like , and AC single-phase systems at (16.7 Hz) and IEC 60038 Standard Voltage Classifications | PDF - Scribd Purchase from IEC Webstore (approx

DC nominal voltages:

preferred nominal DC voltages are provided for specific applications (e.g., telecom, traction), commonly including 48 V , 110 V , 220 V , etc., depending on standard edition.

The standard aims to harmonize electrical systems across borders to ensure:
