Advanced calibrator for CT/PT ratio, phase angle, and relay testing

The GDVA‑402 is an advanced calibrator designed for precision testing of current transformers (CTs), potential transformers (PTs), and protection relays, with programmable outputs and diagnostic capabilities.

The GDVA‑402 CT/PT Analyzer offers precise, programmable output for current and voltage to simulate CT/PT performance, relay actions, and metering functions. It features high-fidelity phase-angle adjustment, data logging, USB/RS‑232 connectivity, and remote interface. Designed for field and factory use, the rugged, portable unit ensures reliable operation. Certified to CE and ISO, it meets standards such as IEC 61850 and IEEE C37.x, making it ideal for commissioning, maintenance, and factory calibration tasks.


Key Features:

  • Programmable CT output (up to 10 A) & PT output (up to 110 V)

  • Phase-angle adjustment and ratio testing

  • Relay simulation and metering verification

  • LCD display with USB/RS‑232 and remote control

  • Safety features: overload, short-circuit, over-voltage

  • Portable and rugged design

  • Compliant with IEC 61850 & IEEE C37.x

  • CE and ISO certified
