SATEC · Prove it

Power quality, measured not guessed

When a bill is disputed, an interconnection is reviewed or a machine trips and the power is blamed, the argument goes to whoever has the data. SATEC meters, power quality analyzers and branch circuit monitors put that data in place, from the service entrance to the individual circuit, on AC and DC.

SATEC has designed and built its own meters, firmware and software since 1987. Dynamic is the SATEC rep for Northern California and Northern Nevada, sizing the metering against the one-line, the code and the CT chain.

Where we put SATEC to work

Three jobs where the facility with the data wins

Measurement is usually the last thing specified and the first thing blamed. Retrofitting it into a live panel costs far more than drawing it in, and the accuracy on the meter's label only reaches the report if the CT chain lets it. These are the three places we specify SATEC most.

Plants: which start sets the peak

A demand charge comes from the highest interval average in the billing period, and two starts that overlap once can set it. Meter the service the way the tariff bills it and the circuits that matter, and the peak becomes a line in a log, not an argument.

PM17x PRO on the service, events stamped to 1 microsecond. BFM-II gives ovens, chillers, compressed air and each line their own kWh.

Data centers: capacity, PUE and the rack

The EPMS shows what the electrical system is doing now. Circuit-level metering and the analytics layer above it show capacity headroom and PUE by hall, customer and rack, and capture the rectifier harmonics and transients on both ends of the UPS.

BFM-II at the PDU and the panelboard, PRO Series at the UPS, ExpertPower for capacity and PUE by area.

Storage and DC: a number that survives a year

A round-trip figure gets judged against a meter on somebody else's site. Meter the DC side and the AC side on the same instrument family, every inverter feed on its own channel, and keep an interconnect record stamped to the microsecond.

PRO Series, DC to 1,500 V. PM17x PRO at the point of interconnect. BFM-II across the inverter feeds.

For the specifier: write the class, the edition and the sensor chain, and the panel shop can build it and the commissioning agent can verify it. Metering mandates come from the code that applies: Title 24 Part 6 §130.5 in California, the 2024 IECC C405.13 in Nevada, ASHRAE 90.1 §8.4.3 for federal and out-of-state work. We size the schedule against the section that applies.

What SATEC makes

From the circuit to the service entrance

PRO Series meters and analyzers

Three boxes in one instrument: a Class 0.2S revenue meter, a power quality analyzer and a setpoint controller.

Class A Edition 3.1 power quality analysis per IEC 61000-4-30
AC and DC on the same platform, DC to 1,500 V
Waveform capture selectable to 256 samples per cycle (PM335, EM235)

See the PRO Series

PM17x PRO power quality analyzers

Current power quality analysis that drops into last decade's cutout, in the same footprint and wiring as the PM17x units already in the field.

Class A Edition 3.1 analysis, harmonics to the 63rd
Time sync to 1 microsecond, so every event carries a stamp
PQ reports, COMTRADE and PQDIF export through PAS

See the PM17x PRO

BFM-II branch feeder monitor

Submetering without a wall of meters: one DIN rail unit across a panelboard.

54 single-phase or 18 three-phase circuits, against two voltage sources
Modbus or BACnet out of the box, for the BMS the building already runs
Virtual channels that total circuits into the load categories a code asks for

13x Series multifunction meters

The Class 0.5S workhorse tier for services, feeders and machines, panel mount or DIN rail.

PM130 PLUS and PM135 panel mount; EM132 and EM133 DIN rail
EM133 runs standalone with no external sensors
Modbus and DNP3; setpoints and data logging

SATEC ExpertPower energy management platform

PAS and ExpertPower software

The data goes somewhere useful: analysis on the bench and energy management across sites.

PAS ships with every instrument at no charge: configuration, automatic PQ reports
ExpertPower: capacity headroom and PUE by area, customer and rack
Allocates consumption to areas, customers or assets for reporting and invoicing

The engineering behind it

Why the number on the report is the number on the label

Accuracy is a system propertyA Class 0.2S meter reading through a 1 percent CT is a 1 percent system.

One CT in the chainHACS sensors feed the meter directly, with no shorting blocks at disconnect.

Split-core, circuit stays liveHACS clips around the conductor, so metering goes onto a running site.

Edition 3.1Class A Edition 3.1 on PRO Series and PM17x PRO, the current revision.

Stamped to 1 microsecondTime sync on the analyzers, so an event at 14:07 is a log entry.

Speaks the building's languageModbus, BACnet, DNP3 and IEC 61850 across the range; we confirm per model.

Questions engineers ask us

Straight answers on metering and power quality

What does Class A Edition 3.1 mean on a power quality analyzer?

IEC 61000-4-30 is the standard for power quality measurement methods, and it has revisions. Class A Edition 3.1 is the current revision of its top measurement class, and the SATEC PRO Series and PM17x PRO carry it. A spec that names Class A without an edition leaves the revision open, so write Class A Edition 3.1.

Why does my submeter disagree with the utility bill?

Often it is the current transformer, not the meter. A Class 0.2S meter reading through an ordinary 1 percent CT is a 1 percent system, and the error grows with every metering point you add together. SATEC HACS sensors feed the meter directly, one CT in the chain instead of two, so the class on the meter is the class on the report.

How do I submeter a panelboard without a wall of meters?

Use a branch feeder monitor. The SATEC BFM-II meters up to 54 single-phase or 18 three-phase circuits from one DIN rail unit, against two voltage sources, and talks Modbus or BACnet to the building management system.

How do I find which load sets my demand charge?

A demand charge comes from the highest interval average in the billing period. Meter the service the way the tariff bills it, with every event time-stamped, and meter the large loads by circuit. A SATEC PM17x PRO on the service and a BFM-II on the panelboards show which start landed on the peak.

Can I meter DC on a battery or energy storage site?

Yes. The SATEC PRO Series measures the DC side and the AC side on the same instrument family, DC to 1,500 V, so the round-trip figure is measured on one platform instead of two.

Can metering be added without rewiring the panel?

Yes. HACS split-core sensors open and close around the existing conductor and feed the meter directly with no shorting blocks, so nothing is cut or re-terminated. A qualified electrician installs them with the circuit de-energized, which keeps the outage to a short planned window.

What do the energy codes ask for in electrical metering?

It depends on the code that applies. In California, Title 24 Part 6 §130.5 calls for service and feeder kW and kWh plus load breakout. Nevada adopted the 2024 IECC, where C405.13 covers new buildings of 10,000 square feet and up; confirm the edition the local building department is enforcing. Federal and out-of-state work often cites ASHRAE 90.1 §8.4.3. We size the metering schedule against the section that applies.
