GE General Electric Technical Specifications: IS200VCMIH2C

This group of setpoints is critical for all overcurrent protection features that have settings specified in multiples

of CT rating. When the relay is ordered, the phase, ground, and sensitive ground CT inputs must be specified

IS200VCMIH2C as either 1 Amp or 5 Amp.

As the phase CTs are connected in wye (star), the calculated phasor sum of the three phase currents (Ia + Ib +

Ic = Neutral Current = 3I0) is used as the input for the neutral overcurrent. In addition, a zero-sequence (core

balance) CT which senses current in all of the circuit primary conductors, or a CT in a neutral grounding con

IS200VCMIH2C ductor may also be used. For this configuration, the ground CT primary rating must be entered. To detect low

level ground fault currents, the sensitive ground input may be used. In this case, the sensitive ground CT pri

mary rating must be entered. For additional details on CT connections, refer to Section 3.2: TYPICAL WIRING

on page 3–5.

The 750/760 relay has 20 logic inputs which can be used to operate a variety of logic functions for circuit

IS200VCMIH2C breaker control, external trips, blocking of protection elements, etc. The relay has ‘contact inputs’ and ‘virtual

inputs’ that are combined in a form of programmable logic to facilitate the implementation of various schemes.

The relay has 14 rear terminal contact inputs. These contacts can be either wet or dry (see Section 3.2.13:

LOGIC INPUTS on page 3–14 for typical wiring of the logic input contacts). External contacts are either open

or closed and are debounced for one power frequency cycle to prevent false operation from induced voltage.

Because of debouncing, momentary contacts must have a minimum dwell time greater than one power

frequency cycle.

The relay also has 20 virtual inputs which are analogous to software switches. They allow all the functionality

of logic inputs to be invoked via serial communications or from the front panel. This has several advantages

IS200VCMIH2C over only having contact inputs:

  • The number of logic inputs can be increased without introducing additional hardware.
  • Logic functions that must be invoked from a remote location can all be done over a single RS485 commu

nications channel.

  • The same logic function can be invoked both locally via contact input, front panel keypad, and/or remotely

via communications.

  • Panel switches can be replaced entirely by virtual switches to save cost and wiring.

Virtual inputs are simply memory locations in the relay which can be assigned a value via communications or

from the front panel display menu \ ACTUAL VALUES \ A1 STATUS \ VIRTUAL INPUTS. If the value stored in memory is

0 then the virtual input is Off, otherwise the virtual input is On. The state of virtual inputs is written as if it were

a setpoint; these values are non-volatile and are found in the Memory Map at locations 0090 to 00A4 hex.

Momentary virtual inputs are simulated by first writing a ‘1’ to the corresponding register followed by writing a

‘0’. Due to communications delay there will be a dwell time of 50 to 200 ms. Maintained virtual inputs are simu

lated by writing a ‘1’ to the corresponding register.
