GENERIC SPECIFICATION FOR

MULTIFUNCTION POWER AND ENERGY METER

SHARK ® 100 METER

2. PRODUCT

2.1 POWER METERS

A. The meter shall be UL listed and CE marked.

B. Power meter shall be designed for Multifunction Electrical Measurement on 3 phase

power systems.

1. Meter shall support 3 element Wye, 2.5 element Wye, 2 element Delta, 4 wire

Delta systems.

2. The meter shall accept universal voltage input.

3. Surge withstand shall conform to IEEE C37.90.1

4. The meter shall be user programmable for voltage range to any PT ratio.

5. Meter shall accept a burden of up to .36VA per phase, Max at 600V, 0.014VA at

120 Volts.

6. The meter shall accept a voltage input range of up to 416 Volts Line to Neutral,

and a range of up to 721 Volts Line to Line.

7. Meter shall accept a current reading of up to 11 amps continuous.

C. Power meter shall use a dual input method for current inputs. Method one shall allow

the CT to pass directly through the meter without any physical termination on the meter,

ensuring the meter cannot be a point of failure on the CT circuit. The second method

shall provide additional termination pass-through bars, allowing the CT leads to be

terminated on the meter. The meter must support both termination methods.

1. Fault Current Withstand shall be 100 Amps for 10 seconds, 300 Amps for 3

seconds, and 500 Amps for 1 second.

2. Meter shall be programmable for current to any CT ratio. DIP switches or other

fixed ratios shall not be acceptable

3. Meter shall accept burden of 0.005VA per phase, Max at 11 Amps.

4. Meter shall begin reading at a 5mA pickup current.

5. Pass through wire gauge dimension of 0.177” / 4.5 mm shall be available.

6. All inputs and outputs shall be galvanically isolated to 2500 Volts AC.

7. The meter shall accept current inputs of class 10: (0 to 11) A, 5 Amp Nominal,

and class 2 (0 to 2) A, 1A Nominal Secondary.
