Power Analysers

NHP’s power analysers are perfect for applications where detailed energy and power analysis is required. With an extremely high sample rate, it’s possible to monitor harmonics up to the 127th order, record sags, swells and other voltage disturbances.

Features and Benefits

Load shedding outputs to prevent overload conditions and thus avoid nuisance tripping protective devices.
Variable control with alarm activation on any available variable
Cost-effective solution for single load/phase monitoring.
