RET670-1MRK002816-AB application program
Intelligent electronic devices (IEDs) provide fast, safe and reliable service for selective protection, monitoring and control for two - and three-winding transformers, autotransformers, boost transformers and generator-transformer block sets, phase-shifting transformers, dedicated railway transformers and shunt reactors. Improvised explosive devices are designed to operate properly over a wide frequency range to accommodate changes in power system frequency during interference and generator start-up and shutdown.
RET670-1MRK002816-AB IED features fast, low-impedance differential CTs with very low protection requirements. It is suitable for differential applications with multiple circuit breaker configurations and can be configured with up to 6 constrained CT inputs. Differential protection with second harmonic and waveform block suppression function, to avoid CT saturation and trip transformer inrush current, fifth harmonic suppression to avoid transformer overexcitation trip.
The RET670-1MRK002816-AB differential function provides high sensitivity using sensitive differentials for low grade internal fault protection based on amplitude measurement and negative sequence directional comparison components.
Product Overview:
RET670 1MRK002816-AB is a digital protective relay with high precision, fast response and flexible configuration.
Technical features:
High precision measurement: Advanced digital signal processing technology can accurately measure electrical parameters such as current and voltage.
Fast response: When a fault occurs in the power system, it can quickly cut off the fault circuit, the operation time is less than 20ms, to prevent the expansion of the fault and equipment damage.
Flexible configuration: Support function setting and parameter adjustment through software to achieve personalized protection solutions.
Main functions:
Mainly used in the protection of power equipment, including transformers, cables, generators and so on.
Detect and respond to failure conditions in power systems such as overvoltage, undervoltage, overcurrent, differential protection, etc.
Remote monitoring and control functions may be available to support remote monitoring of the status of the power system and perform necessary operations.
