Main features of the UMG 605-PRO

The power quality analyzer, in accordance with EN 50160, is particularly suitable for DIN rail mounting. It is used to monitor the power quality in accordance with common standards, e.g. EN 6100024. The UMG 605-PRO is suitable for recording short and long-term flicker as well as for Profibus DP and Profibus DP V0. The UMG has two digital inputs and outputs and an additional temperature measurement input.

HARMONICS

Harmonics are caused by equipment with non-linear characteristics, such as transformers operated in saturation, energy-saving lamps, frequency converters and power electronics. They burden the grid with additional currents and can affect or even destroy equipment. These grid perturbations can be detected and documented using power quality analyzers.

ALARM MANAGEMENT

The GridVis® alarm management system monitors all measurement parameters obtained by the UMG measurement devices. It includes escalation management, logbook function and user administration for individual notifications by e-mail, pop-up window on the monitor, etc.

In addition to monitoring RMS values, short-term interruptions and transients as well as communication with the measuring devices can also be monitored.

REPORTING

An important component of the grid analysis is the report generation of GridVis®. It provides a quick and clear representation of the voltage quality in defined time periods. The power quality reports are based on international standards (EN 50160, EN 61000-2-4, IEEE 519, etc.).

In addition to the PQ reports, energy consumption reports are of great benefit to the user. Generation and dispatch can take place automatically according to freely definable schedules.

FLICKER

Flicker is the subjective impression of visually perceptible fluctuations in brightness caused by temporal changes in luminance or spectral distribution. This is caused by voltage fluctuations.

Above a certain limit, flicker phenomena are disturbing and may be harmful to health. The standard DIN EN 61000-4-15 regulates further details.

MEMORY

Many UMG measurement devices have their own memory with typical recording ranges of up to 2 years. Recording is freely configurable. A 128 MByte memory can store around 5,000,000 memory values, a 256 MByte memory can store around 10,000,000 memory values.

E-MAIL

Notification by e-mail is an ideal tool for alarm and escalation management of the UMG measurement devices and the GridVis® software. This allows recipients to be informed in detail about an event straight away.
