Description
Product Description

The Numerical Relay Tester is designed for modern microprocessor-based protection devices used in power generation, transmission and distribution systems.

Unlike traditional electromechanical relays, numerical protection devices can include multiple integrated functions such as overcurrent, distance, differential, frequency and directional protection.

A modern relay test set therefore needs flexible waveform generation and precise control of electrical parameters.

Testing Functions
  • Numerical overcurrent protection
  • Distance protection
  • Differential protection
  • Directional protection
  • Voltage protection
  • Frequency protection
  • Sequence component protection
  • Harmonic protection
  • Reclosing logic
  • Breaker failure logic
  • Trip timing
  • Binary logic testing
Applications
  • Digital substations
  • Smart grid projects
  • Numerical relay commissioning
  • Protection laboratories
  • Substation maintenance
  • Relay manufacturers
  • Power system research
Main Buyer Concerns

Compatibility

Customers need equipment capable of testing different relay brands and protection functions.

Automation

Large protection systems may require hundreds of test points.

Repeatability

Automated sequences can improve repeatability between tests.

Data management

Engineers need to save settings, waveforms and test results.

FAQ

What is a numerical protection relay?

It is a microprocessor-based protection device that processes measured electrical signals digitally and implements protection algorithms.

Can a numerical relay tester also test conventional relays?

Many universal relay test sets can test both traditional and numerical protection relays.
