Red Phase 4025E Frequency Selective Multimeter. Hire from Megavar for frequency-selective voltage and current measurements on HV power networks.
Description
The Red Phase 4025E Frequency Selective Multimeter is a precision instrument designed to measure voltage and current at a specific test frequency, typically used in conjunction with a Red Phase earth injection test set. It filters out noise and harmonics to provide accurate RMS readings of signals at the injected test frequency—usually 55–60 Hz—making it ideal for substation earth grid testing, step and touch voltage assessments, and current distribution measurements. Rugged and field-proven, the 4025E is widely used by power utilities and commissioning teams for verifying earth system integrity under simulated fault conditions.

• 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

Frequently Asked Questions
Red Phase 4025E Frequency Selective Multimeter

What is the 4025E used for?

It’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.

Minimum hire is 3 days, with weekly and monthly rates available for extended projects.

Yes. We provide Australia-wide delivery and collection, or you may arrange your own freight.
