Yokogawa Releases WT1500 Power Analyzer for High-Voltage EV Testing
The four-channel instrument measures up to 2,000 V DC directly without external dividers.
Yokogawa Test & Measurement has released the WT1500, a four-channel power analyzer designed for high-voltage testing in electrified vehicles and related applications.
What Happened
The WT1500 measures up to 2,000 V DC directly, eliminating the need for external high-voltage dividers that test setups normally require at those levels. The instrument fits in a 2U, 19-inch chassis built for rack-mounted and PC-controlled benches. It offers two input element types: the High Voltage (HV) element handles up to 2,000 V DC and 300 kHz for power conversion systems and energy storage systems, while the Wide Bandwidth (WB) element covers up to 1,000 V at 2 MHz for high-frequency waveforms in modern EV motors. The analyzer supports four power measurements and four motor evaluations including both encoder and resolver signal inputs.
Why It Matters
High-voltage systems in electrified vehicles can run into thousands of volts, requiring external dividers that introduce measurement error and complicate wiring. By measuring up to 2,000 V directly, the WT1500 reduces setup complexity for engineers testing EV power conversion and energy storage components. Its resolver support allows motor evaluation tests without extra equipment, potentially streamlining development workflows.
The Bottom Line
Yokogawa's WT1500 enters a specialized instrument market targeting electrified vehicle test environments. Total power accuracy is specified at ±0.038% at DC and 50/60 Hz. For work requiring more than four channels, up to five units can be synchronized for 20-channel measurement.
