Q2: What is the difference between protection relay and PLC? Why use protection relay for distribution feeders?

A: Protection relays and PLCs are both industrial automation equipment, but there are obvious differences in design objectives, functional characteristics and application scenarios.

Protection Relay features:

  1. Dedicated protection algorithms: Specifically designed for power system protection, with built-in dedicated protection algorithms such as overcurrent, ground fault, differential, distance, fast operation (usually millisecond level), high reliability.
  2. High reliability: Adopts redundant design, self-check function, fail-safe design, ensuring reliable operation during faults, no false operation, no refusal to operate.
  3. Electrical quantity measurement: Directly connects CT/PT signals, high-precision measurement of current, voltage, power, energy and other electrical quantities.
  4. Breaker control: Integrated breaker open/close control, anti-pump, status monitoring, failure protection and other dedicated functions.
  5. Disturbance recorder: Built-in disturbance recorder function, recording waveforms before and after faults, facilitating fault analysis.
  6. Time synchronization: Supports IRIG-B and other precise time synchronization, ensuring event record time accuracy.
  7. Type tests: Passed IEC 60255 and other power protection dedicated standard type tests, including high voltage, high current, electromagnetic compatibility, mechanical vibration and other harsh tests.
  8. Typical applications: Power system protection, substation automation, distribution automation, industrial distribution protection.

PLC (Programmable Logic Controller) features:

  1. General logic control: Designed for general industrial logic control, supporting ladder logic, function block, structured text and other programming languages.
  2. Scan cycle: Program executes by scan cycle (usually milliseconds to tens of milliseconds), not suitable for protection applications requiring extremely fast response.
  3. General I/O: Supports digital, analog, temperature, communication and other I/O modules, strong versatility.
  4. No dedicated protection algorithms: No built-in power protection dedicated algorithms, protection functions need to be programmed by users, difficult to guarantee reliability and operation speed.
  5. No disturbance recorder: Usually no built-in power fault disturbance recorder function.
  6. No dedicated breaker control: No integrated anti-pump, failure protection and other breaker dedicated control functions.
  7. Typical applications: Production line control, process control, machinery control, building automation, etc.

Why use protection relay for distribution feeders?

  1. Fast and reliable fault clearing: When short circuit, ground and other faults occur in distribution systems, faults need to be cleared quickly within milliseconds to prevent fault expansion and protect equipment and personal safety. The dedicated protection algorithms and high-speed operation capability of protection relays cannot be replaced by PLCs.
  2. Protection coordination selectivity: Multi-level protection in distribution systems requires precise time and setting coordination, ensuring only faulty sections are cleared during faults without affecting non-fault section power supply. The multi-stage protection and flexible inverse time curves of protection relays can achieve precise protection coordination.
  3. High reliability requirements: Power protection is the last line of defense for safe power system operation, must guarantee extremely high reliability. Protection relays adopt fail-safe design, self-check function, redundant design, pass harsh type tests, reliability much higher than general PLCs.
  4. Dedicated function integration: Protection relays integrate breaker control, anti-pump, failure protection, disturbance recorder, event record, precise time synchronization and other power system dedicated functions. PLCs need additional modules and programming to achieve these, and difficult to guarantee performance.
  5. Standard compliance: Power system protection devices need to comply with IEC 60255 and other international standards, pass relevant type tests. Protection relays are specifically designed for this, PLCs usually do not meet these standard requirements.
  6. Maintenance and management: Protection relays have dedicated setting management, protection coordination calculation, periodic inspection and other maintenance processes, which are standard practices for power system operation management.

Simple summary: Protection relay is a dedicated device for power system protection, PLC is a general industrial control device. Distribution feeder protection must use protection relay, cannot be replaced by PLC. But in practical applications, protection relay and PLC can be used together: protection relay responsible for power protection and breaker control, PLC responsible for other logic control and data acquisition, exchanging data through communication interfaces.

Q3: What does 5A current input mean? How to select CT ratio? How to set protection settings?

A: 5A current input is the rated current input specification of the protection relay, which needs to be used with current transformers (CT).

What does 5A current input mean?

  • The rated value of the protection relay current input is 5A (amperes), which is one of the international standard rated values for power protection relays (another common standard is 1A).
  • The relay cannot directly connect to large currents (tens to thousands of amperes) in the power system. It must use a current transformer (CT) to transform the large current proportionally to a standard 5A or 1A signal, then connect to the relay.
  • This model is configured with 5A three-phase current input + 5A ground current input, meaning all current input channels have a rated value of 5A.
  • Note: 5A is the rated value of the relay input, not the rated current of the protected line. The actual current of the protected line is determined by the CT ratio.

How to select CT ratio? The CT ratio selection needs to consider the following factors:

  1. Line rated current: CT primary rated current should be slightly larger than the rated current of the protected line, usually 1.2~1.5 times the line rated current. For example, if the line rated current is 600A, an 800/5A or 1000/5A CT can be selected.
  2. Maximum load current: Consider the maximum possible load current of the line (including motor starting, load growth, etc.), CT primary rated current should be greater than the maximum load current.
  3. Protection range requirements: Select CT ratio according to protection sensitivity requirements. Ground fault protection has special requirements for ground CT ratio, usually select smaller ratio (such as 50/5, 100/5) to improve ground fault sensitivity.
  4. CT accuracy class: Protection CT should select protection class accuracy such as 5P10, 5P20, ensuring transformation accuracy under fault large current. Metering CT selects 0.2S, 0.5S and other metering classes.
  5. CT rated output: CT rated output (VA) should be greater than the total load of the secondary circuit (including relay input impedance, wire resistance, contact resistance, etc.), ensuring CT does not saturate during faults.
  6. Standard ratio: Try to select standard ratios (such as 100/5, 200/5, 400/5, 600/5, 800/5, 1000/5, 1500/5, 2000/5, etc.), facilitating procurement and spare parts.

How to set protection settings? Protection setting must be determined by professional relay protection engineers based on system parameters and protection coordination calculation. Main steps include:

  1. Collect system parameters: Including system voltage, system short circuit capacity, line parameters (length, impedance), CT/PT ratio, protected equipment parameters (transformer, motor, etc.), upper and lower protection configuration, etc.
  2. Short circuit current calculation: Calculate maximum and minimum short circuit currents (three-phase short circuit, two-phase short circuit, single-phase ground short circuit) at the protection installation point, as the basis for protection setting.
  3. Overcurrent protection setting:
    • Instantaneous (instantaneous overcurrent): Set by avoiding maximum short circuit current at the end of this line or outlet short circuit current at the next level, usually 1.2~1.3 times the maximum short circuit current.
    • Time-delayed instantaneous: Set by coordinating with the next level instantaneous protection, time grade difference usually 0.3~0.5s.
    • Overcurrent (inverse/definite time): Set by avoiding maximum load current, usually 1.2~1.5 times the maximum load current, time determined by coordination with lower level protection.
  4. Ground fault protection setting: Set by avoiding maximum unbalanced current or coordinating with lower level ground protection, need to consider system grounding method (neutral directly grounded, grounded through arc suppression coil, ungrounded).
  5. Voltage protection setting: Undervoltage usually 0.7~0.8 times rated voltage, overvoltage usually 1.1~1.2 times rated voltage.
  6. Frequency protection setting: Set according to system frequency allowable range, overfrequency/underfrequency setting and time determined by system requirements.
  7. Protection coordination verification: Verify selectivity, sensitivity, speediness between 各级 protection, ensuring correct operation during faults.
  8. Input to relay: Input the calculated settings into the relay through front panel or commissioning software, set CT/PT ratio, protection enable/disable, operation time, output contacts, etc.
  9. Primary injection test: After completing setting, perform primary injection test, simulate fault conditions to verify protection operation correctness and output circuit integrity.

Important reminder: Protection setting is a professional task, must be completed by trained relay protection engineers, following relevant power industry standards and procedures. Wrong protection settings may cause protection false operation or refusal to operate, resulting in serious consequences. It is recommended to perform protection setting calculation and primary injection test before commissioning.

Q4: In stock? Lead time? Price?

A: Currently Order Available. Specific stock of GE P500 series protection relays fluctuates with market.

  • Lead time: Standard 4-8 weeks (need to order from GE through professional channels or global stock allocation). Some common models may be in stock, specific subject to formal quotation.
