Welcome to Eastern Regional Power Committee ::
Introduction This manual er the protection relays using the different tools in PCM600. The manual provides instructions on how to set u a PCM600 project and insert relays to the project structure. The
Flexibility and high functionality for generator protection and control applications Not active product since 2024 REG630 is a comprehensive generator management relay for the protection, control,
To avoid relay mal-operation, set Slope 2 as high as possible. Normally, a high Slope 2 setting causes slow tripping for evolving faults (external-to-internal faults).
REG630 Application Manual - Bay control and measurement - Motor protection - Transformer protection - 2 winding - Feeder protection - Voltage regulation - Busbar protection (voltage and frequency) -
This manual ontains instructions on how to commission the protection relay. The manual can also be used by system engineers an maintenance personnel for assistance during the testing phase. The
Protective relay must be isolated from the high-voltage system but require current and voltage quantities proportional to those on the electric supply system. The standard ratings for protective relays are
It features non-directional and directional overcurrent and earth-fault protection, over/undervoltage protection, and generator-specific functions. The relay
Complete generator protection and control with extensive interconnection protection for distributed generation REG630 is a comprehensive generator management relay for protection, control,
Do not switch off the auxiliary power supply to the protection relay before changes, for example, setting parameter or local/remote control state changes are saved.
The relay shall have comprehensive voltage protection functionality, including at least overvoltage(59), undervoltage(27), positive-sequence overvoltage(47O+), positive-sequence undervoltage(47U+),

1. Description REF630 is a comprehensive feeder management IED for protection, control, measuring and supervision of utility and industrial distribution substations. REF630 is a member of ABB''s
The protection relay also measures phase and phaseto-phase voltages, symmetrical components of the voltages and the residual voltage. In addition, the protection
This technical report refers to the electrical protections of all 132kV switchgear. All calculations are based on the available documentation/ information. These settings may be revaluated during the
REG630 has been extended with low-voltage ride-through, reactive power undervoltage and voltage vector shift protection to further ensure grid stability and reliability, and thus avoid grid
REG630 is a comprehensive generator management relay for the protection, control, measurement and supervision of small and medium sized power generators and generator-transformer units in utility
Changing the overcurrent start value ns only one setting group by default. The number of setti Protection →
Since the relay potential connections must be made phase-to-phase, a 208 volt relay should be selected. A range should be selected so that a pick-up setting of 125 watts or less can be made.
The value of the primary current (Iprim) at which the protection operates at certain setting can be calculated using the formula: I prim = n ( I relay + I u + m I m ) (7)
Protective relay functions and data This technical article will cover the gathering of information needed to calculate protective relay settings, the setting
The relay shall have comprehensive machine/ generator differential protection, including both three-phase differential protection (87G/M) with one low-set (biased) and one high-set (instantaneous)
Feeder Protection and Control REF630 Numerical feeder protection in medium voltage networks The freely configurable relay is intended for protection, control, measurement and supervision of the
Effective relay protection depends on accurate calculations, optimal settings, careful coordination, appropriate selection of relays, and thorough
