KFA310 enables comprehensive and precise testing of solar PV systems — from POI protection relays and anti-islanding functions to inverter grid-support and power quality devices — ensuring safe, compliant, and reliable grid interconnection.

Explore how digital substations drive the need for 6-phase, high-precision, and portable secondary injection test sets for modern relay protection.

Explore how LPITs transform digital substation protection. This article covers IEC 61869 standards, MU integration, and practical simulation testing using the KFA320 relay test set.

With the launch of KINGSINE's new-generation 6-phase handheld protection relay tester KFA320, many customers have raised questions about the built-in battery—such as battery lifespan and battery maintenance. This article provides a clear explanation of all common battery-related topics for KINGSINE testers.

The IEC 61850 standard enables interoperability and automated configuration of Intelligent Electronic Devices (IEDs). In this process, the import of the Substation Configuration Description (SCD) file and the visualization of IED information play a critical role.

The emergence of the IEC 61850 standard, along with its core technologies—SV (Sampled Value) and GOOSE (Generic Object Oriented Substation Event)—has completely reshaped substation architecture and driven a profound digital transformation.
