Ponovo PW41i Protection Relay Test Set Three-phase Relay Protection Tester
PW41i is a reliable protective relay test set with high current output (3×40A) and high
voltage output (4×300V‐advanced version or 3×300V‐ standard version). It is with built‐
in local system so that the testings could be done easily by the relay test set itself. The
PW41i advanced version also can be connected to external PC via PowerTest relay test
software running to do testing as well. PW41i is a favorable and economical testing
solution for commissioning work in distribution grid.
More Options for Different Testing Requirement
*PW41i‐standard version, 3×40A and 3×300V, with local system testings only
*PW41i‐advanced version, 3×40A and 4×300V, with local system and support external PC control and support IEC61850 testings
Features:
- 3×40A, 4×300V/3×300V
- 8 Binary inputs, 4 Binary outputs
- High current and power output, output 3×40A with maximum power up to 400VA/phase
- Auxiliary DC power supply 110V, ADJ(0-300V, software controlled), 220V switchover
- The local software system is designed based on Windows system, which is easy and convenient for operation and upgrade. It supports using templates for various relay testings, for example, G59.
