The PEL113 from Chauvin Arnoux is a three-phase power and energy recorder designed for measuring, storing, and analysing electrical parameters in industrial, commercial, and infrastructure applications. The device enables continuous recording of voltage, current, power, and energy, and is distinguished by its compact design with magnetic mounting. It is suitable for use in various sectors including power generation, industry, buildings, transport, and data centres, where accurate energy accounting and optimisation are required.

Applications

The PEL113 is used in applications requiring detailed energy consumption analysis. This includes energy audits according to ISO 50001, preventive maintenance of industrial plants, monitoring of HVAC systems, and sizing of compensation systems. Particularly in data centres, the device is used for consumption monitoring and analysis to prevent outages and reduce operating costs. It is also applicable in shipping due to its support for 400 Hz measurements.

Functions and Equipment in Detail

The device features three voltage and three current inputs and offers a four-digit digital display with backlighting. It measures RMS and DC values, with voltages up to 1,000 V (AC/DC) and currents up to 10 kA (AC) or 5 kA (DC), depending on the current transformer used. Measurements include active, reactive, and apparent power, as well as corresponding energy values. Additional parameters such as cos φ, tan Φ, power factor PF, crest factor, and THD (total harmonic distortion) for voltage and current are calculated. The breakdown of energy losses enables detailed efficiency analysis.

Technology Explained Simply

The PEL113 operates with a sampling frequency of 128 samples per cycle per phase, ensuring precise capture of electrical signals. Self-powering is achieved via the phase, eliminating the need for an external power supply. Measured values are stored on an SD card, and automatic recognition of connected current transformer types simplifies configuration. The devices are suitable for use in refrigerated rooms down to -20 °C, increasing operational flexibility.

Compatibility and Accessories

The device is compatible with various accessories that extend its functionality. These include adapter housings (e.g. 5A (F), Essailec), coloured identification parts, clamps (e.g. MINI94 (AC), E94, MN93A, C193, J93, PAC93), Ampflex and Miniflex cables, a 600 V power adapter for PEL100 V3, a USB-A/USB-B cable, a transport bag, a Reeling Box (cable winder with magnet), and the DataView software. The PEL Transfer software enables device configuration, connection verification, downloading of measurement data, and result evaluation. The software can also convert electricity consumption into Euros (8 tariff zones).

Mounting and Installation

Installation is performed using magnetic mounting, allowing installation without interrupting the mains power supply. The device is compact and can be installed at various points in the power network, for example on power poles or in industrial facilities. Communication is via USB, Ethernet (RJ45), or Wi-Fi, with the Wi-Fi function operating in both server and access point modes. Data transmission is handled via the PEL Transfer software.

Operational Advantages

The PEL113 offers high measurement accuracy and a long recording duration, which can last several months. The integrated Android app enables diagnosis of electric drives, including measurement of speed, efficiency, and torque without mechanical sensors. The combination of local storage on an SD card and network capability allows flexible use both on-site and in networked environments. The devices are designed for use in harsh environments, with PEL115 models additionally featuring IP67 protection, making them suitable for outdoor use.
