Important key performance indicators such as PUE (Power Usage Effectiveness) or CER (Cooling Efficiency Ratio) can be readily evaluated via all power supply or heat supply paths. The representations of summation power such as ERZ or EIT are not a problem for GridVis® and can be readily visualized with prepared objects. Energy efficiency dashboards With GridVis® power grid monitoring software, certified in accordance with ISO 50001/50006, you can evaluate your PUE as well as other key performance indicators, such as EnPIs. Energy efficiency analysis objects So that you always have the measured values to hand, GridVis® offers a range of visualization objects for user-friendly analysis. The objects can be stored on individual dashboards or in reports. Dashboard and report editor at a glance: Individual topology pages Summary pages with live measured values and alarm indicators are extremely helpful so that operations can draw conclusions, such as in critical situations, as quickly as possible. In this case, the data center can be granularly visualized in any manner from the primary supplies to the final circuits.
Timely recognition of voltage events means weaknesses can be detected and unscheduled shutdowns can be avoided. Power quality must be monitored according to normative specifications such as EN 50160, EN 61000-2-4, IEEE 519 and ITIC (CBEMA). The combination of Janitza network analyzers and GridVis® provides prepared power quality reports and special tools for evaluating electrical high availability. Electrical availability With GridVis® it is possible to monitor and evaluate electrical high availability. The high availability report makes it possible to summarize many measurement points in one report. It is ideal for complex power supplies with several redundancy paths. The high availability report at a glance: Evaluation of all critical nodes in one report The event browser provides a comprehensive overview of the voltage, current and frequency events that have taken place. The precise illustration of processes, combined with key information and measured values, enable the event browser to provide accurate analysis of all events. This also provides an ideal foundation for monitoring what are known as catcher systems. Catcher systems are systems that need to switch between two paths in a very short time virtually without interruption. The event browser at a glance: Power quality reports The power quality in the ancillary supply equipment not provided by the electric utility must comply with Class 2 according to the EN 61000-2-4: 2002 standard, while Class 1 applies between the UPS and protected sockets. Compliance with the compatibility levels defined in EN 61000-2-4 must be 100%. GridVis® generates automatic reports that evaluate all grid compatibility levels in compliance with all relevant standards and also describe the quality of the voltage provided. These include, for example, the voltage distortion, individual harmonics, frequency and voltage. PQ objects Any events and transients that occurred can be conveniently summarized on your dashboards with the Power Quality objects. For example, the ITIC (CBEMA) object can be used to compare events that occurred with the tolerance limits set out in the standard. Redundancies and nominal currents The utilization report from GridVis® means nominal currents over the entire power supply system with primary and final secondary distributors can be displayed and evaluated. The report shows, in tabular form, the utilization of all selected measurement points whilst taking the safeguards and MIN/MAX into account. The utilization report at a glance:
In addition to energy transparency and power quality, residual current monitoring (RCM) also plays an important role and is a requirement in standards for data centers. The functionality of TN-S systems can be monitored and logged using a comprehensive residual current monitoring system. Fires due to insulation faults and failures can be detected and prevented before they occur. Insulation measurements as part of the retest can be omitted and the resulting downtime can be reduced considerably. GridVis® provides many options for analyzing residual currents in detail. RCM report The RCM report provides a quick overview regarding the state of your power supply and differential currents. The clear color-coding enables quick statements to be made. In addition, the report is useful when satisfying the need to provide verification. Alongside the standard report, it is also possible to create customized RCM reports such as those with additional evaluations and courses of frequencies, types of residual currents and the power associated with them. The RCM report at a glance:
In colocation data centers, cost centers must be established and their energy metering values must be provided on a monthly basis. With MID measurement devices such as the UMG 96-PA-MID+ or MID- direct meters, the values for individual racks or rental areas can be recorded, charged and assigned to customers by means of cost centers. GridVis® provides prepared reports or flexible raw data exports to this effect. Cost centers GridVis® can also be used to assign several measurement points to a customer and calculate totals by means of virtual measurement devices. Extensive energy reports and data exports as well as a customized energy bill can also be generated. Professional energy bill creation at a glance:
