G59/3 Voltage & Frequency Stability Tests Using DVS3 Mk 1 and Time Delay Relay

New stability test procedures, introduced in the G59/3 standard for Embedded Generator Connections, require precise timing. This is something that the DVS3 Mk 1, an industry standard set for G59 testing, cannot currently provide. This paper provides a reliable method for testing to the G59/3 standard using an external precision timer with the DVS3 Mk 1.
