MONITORING

As indicated in the Circuit Breaker Monitoring Capabilities section above.

NOTE: This is confirmation you have not selected SF6 Gas Moisture, Interrupter Contact Life, Interrupter Tanks Heaters, Cabinet Heater, Mechanism Charging Motor, Generic DC Voltage, Generic Pressure, or Generic Temperature from the Circuit Breaker Monitoring Capabilities section above.

SF6 Gas Moisture

Is there a desire to monitor the SF6 gas moisture, in addition to pressure/density? Note: Dew Point Sensors must be mounted as close to the SF6 tanks as possible for accurate measurements. They should not be mounted on the fill port, at the end of a long, narrow pipe.

Yes

No

Interrupter Contact Life

What is the maximum short-circuit fault current of the breaker or electrical system, whichever is less? (Amps Max.)

What is the bushing CT ratio of the current tap being used? (? : 5)

Calculating the correct CT Pickup Coil Size for the Bushing CT Secondary Current

Length of Pickup Coil Cables needed?

8 - Foot

30 - Foot

Part Number	CT-20	CT-30	CT-50	CT-100	CT-160	CT-250	CT-400	CT-800
Full Scale Rating (A)	20	30	50	100	160	250	400	800
Range (A)	1.4-20	2.1-30	3.5-50	7-100	11.2-160	17.5-250	28-400	56-800

Example:

Maximum Short-Circuit Current = 35,000 Amps,
Bushing CT Ratio = 1200:5
Reduce 1200:5 CT Ratio to 240:1
35,000 Primary Amps divided by 240 = 145.8 Secondary Amps
Select the CT Pickup Coil with a Range that encompasses the calculated Secondary Amperage from the table.

Interrupter Tanks Heaters

Do the interrupter tanks have heaters, controlled by a thermostat?

Yes

No

Do you want to monitor the heaters? Note: If yes, a UPSM-241 is needed.

Yes

No

Cabinet Heater Circuits

Are any of the cabinet heaters controlled by a thermostat?

Yes

No

How many with a Thermostat?

How many without a thermostat?

Note: A UPSM-241 is needed for each cabinet heater circuit with a thermostat. An OM-ACCT is needed for each cabinet heater circuit without thermostat.

Mechanism Charging Motor

Is the mechanism charging motor powered by AC or DC? Note: An OM-ACCT is needed to monitor AC-powered motors. An OM-DCCT is needed to monitor DC-powered motors.

AC

DC

Generic DC Voltage Monitoring

Note: DC voltage 0-150VDC, use OM-DCVT

Generic Pressure Monitoring

What is the maxium pressure?

BAR ABS

BAR

PSIG

kPa

Generic Temperature Monitoring

NOTE: Temperature -40o C to +120o C, use OM-TS.

OTHER CONSIDERATIONS

Alarm Status & Monitoring Data

Do you plan to connect the Optimizer3 to your substation network to retrieve alarm status and monitoring data?

Yes

No

Note: DNP3 is the only data retrieval protocol available.

What is the preferred data retrieval protocol?

Optimizer3 Mounting

Where will the Optimizer3 be mounted?

In the existing breaker control/mechanism cabinet

In a new/separate enclosure

Magnetic Mounting

Do you want to magnetically-mount or screw-mount the Optimizer3 to your cabinet or panel?

Magnetic Mount, use OM-MMK

Screw-Mount
