Differential protection for transformers, generators, and lines are included in many of the high-end Arcteq protection relays. Customer Service Manager Joni Leppilahti shows you how these functions are configured and how to take full advantage of the convenient wizard for transformer differential protection.
Customer Service Manager Joni Leppilahti introduces you to the differential protection configuration on a protection relay for a two-winding transformer, and shows you how to test it with Omicron CMC356. The tests include a characteristics test, an operation time test, and a harmonics blocking test.
The AQ 200 series transformer protection devices, AQ-T215 and AQ-T257, support automatic voltage regulation by controlling the tap changer. In this training Application Engineer Niko Muotio demonstrates how to set up the voltage regulator’s low and high limits, the tap position indication settings, as well as other settings relevant to the regulator.
AQ-200 series transformer protection IEDs AQ-T215 and AQ-T257 support automatic voltage regulation by controlling the tap changer. This training by Mr. Niko Muotio goes through the steps needed to set up voltage regulator low and high limits, tap position indication settings, and other settings.
Arcteq has developed the communication tool AQwire which is very handy when configuring, for example, the IEC 61850 communication protocol in a protection relay. Application Engineer Raj Kumar explains how to use this tool in a real environment, and how to test the communication of all communication protocols available in AQ 200 products.
Application Engineer Niko Muotio explains how to use both the basic and the more advanced features of the mimic editor in AQ-25x protection devices. These features include adding and editing items, images and text, as well as adding control functionalities and measurements to items. You will also learn how to manage multiple mimics with a single device.
Customer Service Manager Joni Leppilahti gives an introduction to relay communication with the IEC 61850 communication protocol with GOOSE. He also demonstrates how to configure the protocol and GOOSE for an AQ 200 series device, and how to test the configuration with Arcteq’s AQwire communication tool.
