CHAPTER 2: PRODUCT DESCRIPTION

2.5.1 Protection elements
The operating times include the activation time of a trip rated form-A output contact unless otherwise indicated. FlexLogic
operands of a given element are 4 ms faster. Take this into account when using FlexLogic to interconnect with other
protection or control elements of the relay, building FlexLogic equations, or interfacing with other intelligent electronic
devices (IEDs) or power system devices via communications or different output contacts. If not specified, the operate times
given here are for a 60 Hz system at nominal system frequency. Operate times for a 50 Hz system are 1.2 times longer.
