HPL High Tension (HT) Energy Meters are designed for precise energy measurement and monitoring in high-voltage industrial and utility applications. These meters are typically CT/PT operated and comply with Indian and international standards for accuracy and reliability.
-
Voltage Rating: Suitable for HT networks, typically 11kV or 33kV (via CT/PT)
-
Current Rating: Supports standard CT secondary currents like 1A or 5A, scalable based on CT ratios
-
Accuracy Class: Class 1.0 or Class 0.5S, suitable for commercial billing and energy accounting
-
Measurement: True active, reactive, and apparent energy monitoring with import/export, maximum demand, power factor, and power quality analytics
-
Display: Large backlit LCD with multi-parameter display and event diagnostics
-
Communication: Optical port, RS485 (Modbus RTU), and other communication protocols for integration with SCADA and AMI systems
-
Data Logging: Load profiles, event and tamper logs, time-of-day registers, and tariff recording
-
Tamper Detection: Comprehensive protection against phase loss, reversal, and external tampering attempts with event recording
-
Environmental Rating: Suitable for harsh environments with robust casing and IP54 protection
-
Installation: Panel or DIN rail mountable, designed for robust industrial applications
-
Compliance: IS 14697, IEC 62052-11, IEC 62053-22, and DLMS/COSEM protocol adherence
-
HPL 10-60A 3 Phase Counter Energy Meter: Popular HT meter with accuracy maintained even under wide voltage and current fluctuations, tamper proof design, and compliance with IS standards. Dimensions approximately 169x200x82 mm.
