The Sonel PQM-707 Power Quality Analyser is an autonomous, versatile and rugged power quality meter with a 7” touchscreen display. It is capable of accurately measuring and analysing electrical parameters and can be used to diagnose network faults. The Sonel PQM-707 Power Quality Analyser measures all electrical parameters in accordance with the IEC 61000-4-30 Class S standard and measures electrical energy according to the European standard EN 50160, ensuring high accuracy.
The Sonel PQM-707 Power Quality Analyser supports the following measurements and capabilities:
Data is visible via the Sonel PQM-707 Power Quality Analyser’s large, 7” colour, touchscreen display with an 800 x 480px resolution. Additionally, measurements can be recorded to the removable memory card, providing unrestricted data storage. Once downloaded to a PC, results can be analysed and organised into reports using Sonel’s Analysis Software.
To facilitate ease-of-operation, the Sonel PQM-707 Power Quality Analyser includes an intuitive interface and is supplied with a stylus which allows the user to operate the PQA whilst wearing dielectric gloves. Other practical features include a rechargeable lithium-ion battery, an ergonomic casing which provides access to all the unit's measurement and communication sockets, and a folding lid to protect the screen. The Sonel PQM-707 Power Quality Analyser is IP51-rated: it is protected against dust and water ingress.
The Sonel PQM-707 Power Quality Analyser has a wide scope-for-use; it is ideal for maintenance staff as its mobility, autonomy and eclectic measurement capabilities mean issues in supply networks can be diagnosed there and then. The Sonel PQM-707 Power Quality Analyser is also suitable for professional power engineering, network analysis, and maintenance services in industrial plants.
Furthermore, this PQA can analyse networks with voltages between 54V and 760V. The Sonel PQM-707 Power Quality Analyser can be used to analyse mains with current and voltage transducers, as well as single-phase, split-phase with common N, three-phase WYE with and without N conductor, three-phase Delta, and three-phase WYE and Delta Aron mains networks.
The Sonel PQM-707 Power Quality Analyser is an ergonomic and easy-to-use PQA with an eclectic range of measurement features.
