Relays are often utilized in electrical facilities as isolated switches or protective devices for various electrical equipment. Due to the mechanical operation of relays, the contacts are prone to contact degradation, so it is important to regularly test for the electromechanical, electronic and protection schemes to ensure safe and reliable operation, and to avoid a faulty relay system acting up during critical operations. To assess relays and protections schemes, consider investing in a relay test set or a power system simulator.
Doble offers a wide selection of relay testers for comprehensive troubleshooting and preventive maintenance. One of their popular product lines is the F2000 family of single phase relay testers. These test instruments are designed for testing complete protection schemes and individual relays. They can conduct steady-state, transient simulation and dynamic-state tests. Below is a comparison of features of the devices in the F2000 Series.
