HT Instruments VEGA74 – Single/Three-Phase Power Quality Analyzer

• 9 types of electrical systems available
• DC/AC TRMS voltage for single-phase/three-phase systems up to 600V
• Current DC/AC TRMS single-phase/three-phase systems up to 3000A
• USB and Wi-Fi connection
• TFT LCD capacitive touchscreen

VEGA74 is a single-phase/three-phase network analyzer capable of acquiring and recording 600 electrical parameters simultaneously. The use of VEGA74 is very simple and intuitive, thanks to the interface with color touchscreen display with icon structure. VEGA74 is ideal for solving problems deriving from low network quality, voltage anomalies, harmonics and high energy consumption which can then become much more harmful and complex phenomena to keep under control if neglected for too long. The measurements taken can be transferred to a PC with USB or WiFi connection with a dedicated software in order to analyze the data and create printed reports.

The instrument is equipped with a TFT color LCD display, with capacitive “touch-screen” that can be handled simply with the touch of a finger by the user and is structured with an icon-based menu allowing the direct selection of measurement functions for quick and intuitive use.

This instrument can perform the following tests:

• PQA – Real-time measurement and recording of mains parameters, harmonic analysis, voltage anomalies (sags, swells), power/energy consumption in single-phase and three-phase generic systems
• AUX – Measurement and recording of environmental parameters (illuminance, air temperature, humidity) by means of optional external probes and DC voltage signals
• LEAKAGE – Measurement and recording of leakage current (by means of the optional transducer clamp HT96U)
