HPL Electric and Power Limited - Panel Meter

This advanced three-phase energy meter is engineered for precise energy measurement across a wide operating range, maintaining high accuracy throughout. It supports a wide auxiliary supply range of 80300V AC/DC, ensuring compatibility with diverse electrical networks. The meter allows push-button site programming of CT/PT ratios and offers network configuration for both star (3-phase 4-wire) and delta (3-phase 3-wire) systems.

Equipped with a bright 3-line, 14mm LED display, it provides clear visibility of energy parameters. The meter features auto-scroll and scroll-lock functions, an auto-adjustable decimal point, and a test mode display for easy verification. Password-protected programming ensures security, making it ideal for commercial, industrial, and utility energy monitoring applications.

This versatile three-phase energy meter is designed for precise and reliable measurement across a wide range of applications. The meter maintains accuracy throughout the range and features separate colored LED indicators for R, Y, and B phases, making it easy to monitor phase status at a glance. It supports PT programming from 110999 kV / 110750 V and CT programming from 19999 A / 15 A, while allowing direct voltage measurement up to 750V without the need for external PTs.

The meter offers flexibility, allowing three-phase meters to be used as single-phase meters without compromising accuracy. Advanced diagnostic features enable checking of connections and phase sequence directly on the display. Users can customize their view with a favorite display field option, and the meter provides LED alerts for reverse current, over-voltage, over-current, and abnormal frequency. Push-button CT/PT ratio programming and field-selectable network options (star & delta) make it suitable for industrial, commercial, and utility energy monitoring applications.

Product Description

This three-phase LED energy meter delivers accurate and reliable measurement across the entire range. It features a three-line LED display that clearly shows Voltage, Current, Power Factor (PF), Frequency, and Power, enabling real-time monitoring of electrical parameters. The meter supports PT programming from 110–999 kV / 110–500 V and CT programming from 1–9999 A / 1–5 A, with direct voltage measurement up to 650V without the need for external PTs.

Equipped with diagnostic features, the meter allows users to check connections and phase sequence directly on the display. It also provides HIGH alerts when voltage exceeds 650V or current exceeds 7.5A. The push-button programmable CT/PT ratio and field-selectable network option (star & delta) make this meter flexible and ideal for industrial, commercial, and utility energy monitoring applications.

This high-precision three-phase energy meter is engineered for LT and HT network applications, offering reliable measurement for industrial, commercial, and utility setups. It complies with IS13779 and IEC 62053-21/22 for Class 1.0 and IS14697 and IEC 62053-22/23 for Class 0.5s, ensuring accuracy and consistency across all ranges. The meter features a three-line backlit LCD display with selectable resolution in kWh, MWh, or GWh, depending on the programmed CT/PT ratios. Separate pulse LEDs for active (kWh) and reactive (kVArh) energy allow easy onsite verification of readings.

Equipped with an RS485 MODBUS communication port, it enables seamless integration into automation and monitoring systems. The test mode lets users cross-check connections and configured parameters, while the snapshot feature captures energy parameters whenever CT/PT is programmed or energy is reset. This combination of accuracy, flexibility, and connectivity makes it ideal for modern energy monitoring and management.
