Megavar delivered HV testing and protection system commissioning for the Bluegrass BESS (Blue Grass) project in Queensland's Western Downs, working in partnership with
• Frequency-selective measurement tuned to 55–60 Hz test signals
• Accurately reads voltage or current while rejecting unrelated interference
• True RMS measurement ensures precision on injected signals
• Ideal for step, touch, and transfer voltage testing
• Designed to work alongside Red Phase 4024B/4023 earth injection systems
• Highly immune to power system noise and harmonics
• Clear digital display with stable readings even in harsh conditions
• Rugged, transportable housing for field and substation use
• Supplied with voltage probes and current clamps

View Hire DetailsIt’s used to accurately measure test voltages or currents during earth grid tests where an injected signal (usually 55–60 Hz) is applied. It ensures readings reflect the injected signal only—not background power system noise.
Power system environments are electrically noisy. The 4025E isolates and measures only the test signal frequency, avoiding measurement errors from harmonics, switching noise, or nearby live equipment.
• Step and touch potential testing
• Transfer voltage measurement
• Substation earth grid integrity tests
• Current distribution across structures or electrodes
It is optimised for use with Red Phase 4024B + 4023 injection sets, but it can be used with other frequency injection sources operating at the correct test frequency (typically ~58 Hz).
Yes. It comes with voltage probes and current clamps, allowing it to measure either parameter, depending on the setup.
Absolutely. It is built into a robust portable enclosure, suitable for use in substations, switchyards, and outdoor environments.
• Red Phase 4025E meter
• Voltage probes and input leads
• Current clamp (optional)
• Operation manual and rugged case
• (Optional) test frequency configuration support
Yes. We offer remote guidance for frequency injection test setups and interpretation of measured results.
