Electrical Systems Anomalies

Electrical SystemsProtective relays are designed to respond to electrical systems anomalies in:
• Current
• Voltage
• Frequency
• Phase angle
• Direction of current or power flow
• And other parameters

Protective relays should be acceptance tested prior to being placed in service. Thereafter, they should be tested periodically to ensure reliable performance.  In normal industrial applications, relays should be tested at least every 2 years. In critical systems, testing should be conducted at least annually.
