A High Voltage Metering Box, also known as a High Voltage Electricity Metering Cabinet or HV Metering Panel, is an essential component in the electrical infrastructure, particularly in industrial and utility applications where high voltage electrical power distribution and monitoring are required. It is designed to safely house and facilitate the measurement of electrical parameters such as voltage, current, power factor, and energy consumption in high voltage electrical systems.
The main voltage and current transformer wires are extended for connection via conductive rods inside the porcelain casing. These transformers are mounted on a pallet, which is then lifted onto the tank lid using support rods, immersed in transformer oil. Additionally, the high-voltage and secondary lead bushings are fitted onto the tank cover, and an oil drain plug with a grounding bolt is secured to the side of the tank.
Advantages
1. Safety: Designed with insulated and earthed enclosures to protect against accidental contact with live parts.
2. Accuracy: Utilizes precision meters to ensure the readings reflect actual energy usage without significant errors.
3. Accessibility: Provided with secure yet accessible compartments for easy meter reading and maintenance.
4. Customizability: Configurable to accommodate various voltage and current ratings, and can be integrated with communication devices for remote monitoring.
5. Environmental Protection: Weatherproof and resistant to dust and moisture, ensuring reliable operation in outdoor and harsh environments.
Applications
High voltage metering box helps monitor the energy usage, ensuring efficient energy management and facilitating accurate billing by utilities for Industrial Plants, Commercial Buildings, Utility Substations, Renewable Energy Plants, Data Centers, Infrastructure Projects including Highways, railways, and airports.
