A metering panel is a component of a power switchboard that houses and displays electrical measurement instruments. It provides a centralized interface for monitoring parameters such as voltage, current, power, energy consumption, and power factor in industrial and commercial power distribution systems.
Typical ratings include a rated voltage of 400 V AC (three-phase), a rated current of 100–630 A (depending on transformer rating), a frequency of 50/60 Hz, and an accuracy class of 0.5 for active energy metering. The rated insulation voltage is 690 V, and short-circuit withstand is 10–50 kA for 1 second. Always verify model-specific values with the manufacturer.
Relevant standards include IEC 61439 for low-voltage switchgear assemblies, IEC 60038 for standard voltages, IEC 62053-21 for electricity metering equipment, IEC 60529 for degrees of protection, and GB/T 11253 for cold-rolled steel. These standards serve as procurement references; compliance must be confirmed with the supplier.
Selection should consider the system voltage, current transformer ratings, required accuracy class, environmental conditions (temperature, humidity), degree of protection, and physical dimensions. It is essential to verify that the panel's specifications match the application requirements and that all standards are met by the legal manufacturer.
