New features, more applications with PQube 3 Power Analyzers Data Centers UPS Monitoring Utilities grid operators, DER/PV integrators Utilities & commercial /industrial Manufacturing Healthcare facilities New product (summary) New features (summary)

Data Centers Problem solving: Explain, justify costly investments in design for reliability – during design and during operation Problem solving: measure & optimize power profile optimization up to four (4) 3-phase PDUs NEW ! Problem solving: Prevent PDU overloading (breaker trips) ---- Load shedding ---- colocation /shared hosting / in-house

Data Centers NEW Load shedding: CRAC = computer room air conditioning Firmware 3.7.0 Q3 2018 NEW Load shedding: Turn OFF CRAC units before the PDU overloads (circuit breaker trip) and Turn CRAC units back ON when the overall consumption is back within limits CRAC = computer room air conditioning

Data Centers How load shedding works Ex: 2 threshold load shedding Consumption (PDU load) CR AC #2 OFF Relay 2 Trigger threshold Hysteresis Relay 2 Return Threshold CRAC #1 OFF Hysteresis How load shedding works Ex: 2 threshold load shedding Watts Relay 1 Trigger threshold Relay 1 Return Threshold Up to 4 X 3-phase loads or up to 8 thresholds … Relay 1 Active Relay 2 Active

Data Centers Load shedding works with relays… which relays? RM8 – 8 relay output module Up to 2 modules …. 16 relays

Data Centers Impact of earthquake on specific racks/equipment: The “shake” is not identical from one rack to the other Detect seismic wave impact or mechanical shock impact – LOCALLY

Data Centers : who to sell to ? PDU RACKS UPS POC GENSET

Manufacturing: alarm & control New! RM8 + PQube 3 or PQube 3e 8 additional relays 1+8 = 9 relays New! PQube 3r PQube 3 with 3 additional relays 1+3 = 4 relays

Utilities: grid operators, DER/PV integrators Problem solving: insure generation performance remains in compliance with regulations during and after commissioning Voltage /VAR response Voltage/ frequency ride through Net /import /export energy Solar and environment conditions Grid stability : real time measurements, phasor measurements – > New! GRID ANALYZER

Utility Grid operators, DER/PV integrators

Monitoring UPS performance Problem solving: identify root cause of power outage Did the UPS work properly? NEW! : Input AND output power monitoring NEW! : assess UPS equipment performance = efficiency! Firmware 3.7.0 Q3 2018

Monitoring UPS performance With PQube 3e and VAT1-600! Option: Battery bank monitoring

Monitoring UPS performance

Utilities, oil/water treatment industries Problem solved: integration of PQube 3 analyzer with existing SCADA systems Communication protocol : DNP 3.0 (IEEE 1815-2012) Level 1 – polling data points Level 2 – alarm when value exceeds a dead band. (configured by the DNP3 client application) Level 3 – encryption (version 3.7.0) DNP3 opens door to larger bids…

New features Summary EN 50160 embedded reports Protocol DNP3 2kHz ~ 150kHz conducted emissions: > Phase by phase color maps (optional) > Separate sensitivity for 2-9kHz and 8-150kHz Vibration detection and recording Analog channels offset configurable

This was “what’s new” Thank you! Questions , please…

New in firmware 3.6.x (3.6.3 released Apr 2018) Embedded EN 50160 reports Vibration ON/OFF detection Better screen display visibility of events in progress New in 3.6.3!

Latest HF impulse (May, Belgium)

Improvements Handling large amounts of events Summary counter events after a threshold per hour /per day is reached. Dual voltage mode : support for the VAT1-600 4th channel + GIF improvements Model names instead of PQube3 part nb in screen, web pages, files, emails. Max zoom out for N-E in waveform Norwegian translation Blinks light blue when firmware upgrade in progress SNTP-NTP lock/unlock sign Harmonic max in 10min CSV!!!! Can write Setup.in or setup.ini (web or USB) to change config Modbus battery voltage and current, charge are now correct Fixes: In some cases, events and trend files cannot be accessed via the Web page (“erro 404 file not found) Frequency spikes in trends and 10sec files (rare occurrence) PQub3e displays loads 6, 7, and 8 when they are OFF Field separator with Power_Energy CSV, and separator for 2kHz-150kHz CSV files not working if non default (“;”) PQube 3 not calculating the neutral current correctly unless you enter CT ratio on I4 Split-phase mode power incorrect if the third current channel is connected.

Using ATT2 with PQube3 coverage on how to set up the PQube3 with only the Analog inputs connected for measuring PV output. The 10 page ATT2 manual does not even mention: Since you do not have AC connected to the PQube 3, be sure to set the power configuration to “Fixed Sampling (No Mains)”. Otherwise, your PQube 3 will not lock on as it’s looking for voltage on L-N terminals. There is an enormous opportunity for measuring PV – certainly here in the UK. I spent Wednesday Morning on the Roof of the USB Building at Newcastle University where we have a PQube3e in an External Housing I spent Thursday Morning on the Roof of the Pandon Building of Northumbria University (located in Newcastle) where we have 3 PQub3’s monitoring 3 different technologies of PV manufacture – here we are looking at the output of the Inverter.

Dual voltage : Dual Voltage mode Support for the secondary voltage N-E channel Wiring HV side - > VAT1 VAT1 – > PQube 3 current terminals WYE (STAR) (4-wire) Va->I1, Vb->I2, Vc->I3, Vd->I4 DELTA (3-wire) Va->I1, Vb->I2, Vc->I3 Single-Phase (2-wire) Va->I1, Vd->I4 With Firmware 3.6.0
