High-performance calibrator for CT/PT ratio, phase, and relay testing

The GDVA‑405 is a precision calibrator designed for testing current transformers (CTs), potential transformers (PTs), and protection relays with programmable outputs and advanced diagnostics.

The GDVA‑405 CT/PT Relay Protection Calibrator is engineered for comprehensive calibration and testing of protection systems. It provides programmable high-precision output for current and voltage to simulate CT/PT behaviors, relay performance, and metering checks. Featuring a digital interface, step sequencing, data logging, and safety protections, the GDVA‑405 is ideal for commissioning teams, utilities, and factory calibrations. Its portable, rugged design supports field conditions, and it's CE/ISO certified, meeting standards like IEC 61850 and IEEE C37.x.


Key Features:

  • Programmable CT (up to 10 A) and PT (up to 110 V) outputs

  • Phase angle adjustment and ratio testing

  • Relay simulation and metering verification

  • Digital display, USB/RS‑232, and remote control

  • Safety protections: overload, short-circuit, and over-voltage

  • Portable rugged case suitable for field use

  • Compliant with IEC 61850, IEEE C37.x standards

  • CE and ISO certified
