Qinghao Electric is developing and producing a variety series LV MV and HV switchgears.
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.
Please check below quick links for other product types.
Functions
1. Metering Equipment: They contain specialized meters and transducers capable of accurately measuring high voltage (typically above 1,000 volts) and high current electrical flows. These may include digital multifunction meters, current transformers (CTs), and potential transformers (PTs) to step down the voltage and current to safer levels for measurement.
2. Isolation and Protection: The metering box often includes isolation switches or disconnectors and protection devices like fuses or circuit breakers to protect the measuring instruments from overloads and short circuits.
3. Data Communication: Modern high voltage metering boxes may be equipped with communication interfaces (like Modbus, Ethernet, or wireless options) for remote monitoring and data collection. This allows utilities and facility managers to track energy usage, detect anomalies, and optimize the electrical system's performance.
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.
