Instruction for the

Cutler-Hammer Type MPCV

Network Protection Relay

Testing

Electrical: The relay shall be tested for critical parameters over

the temperature range of -40°C to +120°C for 24 hours.

Submergibility: Waterproof to 0.5 atmosphere.

Burn-in

Each relay is burned-in for 24-hour period including 5 hours at

-40°C, 5 hours at 85°C, and 1 hour at 120°C, 10 hours at

25°C and ramp time is 4 hours.

Settings

All settings can be edited through a digital pendant, which

plugs into the unit while the relay is powered. The trip and

close operations along with remote communications are inhib-

ited and the float light is flashing while editing.

System Voltage (Metered)

216, 380, 400, 416, 433, 480, 600 volts.

TD: 0.25 to 300 seconds, instantaneous overcurrent pickup is

enabled.

Increments: 0.25 second, 20 seconds.

infinite and only permit tripping on insensitive OC value.

Contact: NO (Normally Open), NC (Normally Closed).

Tolerances

The relay shall operate within the tolerance shown while

operating over the normal temperature range of -20°C to

+110°C and the normal network voltage range of 12 to 190

Vac.

Sensitive Trip: ±5% of setting or ± 0.5 mA, whichever is

greater.

Instantaneous Trip: ±5% of setting or ±0.1 A, whichever

is greater.

Insensitive Trip: ±5% of setting or ±0.1 A, whichever is greater.

Time Delay: ±1% of setting.

Phasing Voltage: ±5% of setting or ± 0.2 volts, whichever

is greater.

Phasing Angle: ±1 degree of setting.

Phase Compensation Angle: ±2 degree of setting.

Trip and Close Angle: ±1 degree of setting.

Operation

Automatic Trip

The trip contacts shall close within 5 cycles of reverse cur-

rent detection. The magnitude and direction of the current

must exist for at least 2 cycles to initiate trip operation.

Sensitive — The relay shall permit a trip when the reverse

current is in the trip region and magnitude is equal or greater

than the sensitive current setting.

Insensitive — The relay is set to insensitive mode when TD is

set to INF.

Time Delay — The delay starts when reverse current is in the

trip region and has a magnitude equal or greater than the

sensitive current setting. The delay stops when the current is

less than the sensitive current setting. The relay shall also ini-

tiates an instantaneous trip when the reverse current is equal

or greater than the overcurrent setting.

Watt-Var — The relay rotates the trip region by 60° and

initiates a trip when the instantaneous reverse current is

equal or greater than the overcurrent setting.

Manual (Remote) Trip

Initiated via PowerNet by a ROBO (Remote Open Block Open)

command. The relay shall not permit any trip or close opera-

tion while the command is active. The Clear ROBO command

will allow the relay to assume normal automatic mode.

Automatic Close

The relay shall permit a closure when the phasing voltage

is in the close region and the magnitude is equal or greater

than the phasing voltage setting, ML. The close contacts shall

close within 5 cycles of phasing voltage detection. The mag-

nitude and direction of the voltage must exist for at least 30

cycles to initiate close operation.
