RED PHASE 4025D and Recoil 545

The Model 4025D Tunable Multi meter is a frequency selective ammeter and voltmeter used to measure the magnitude and phase angles of signals produced by the Model 4024/4024B Injection Units. The voltmeter part of the 4025D allows touch and step voltages to be measured easily and accurately, which is important for the safety of both the general public and utility
personnel. The current input is specifically for use with a (Rogowski) Type 545 worm coil or a LEM~flex RR3020 AC current probe . The Rogowski coil and LEM current probe are available as optional accessories. These accessories are very convenient current measuring devices, which can simply be wrapped around current carrying structures. The ability to measure currents in various structures is important in tracking earth currents during investigations. Utility engineers need an accurate picture of the earth currents flowing in substations, power stations and similar large installations when designing protection systems. The Multimeter operates in the 40 – 69 Hz range, catering for both 50 Hz or 60 Hz power frequencies. The high quality of the Multimeter’s filters allows it to be used at frequencies up to a limit of 1Hz from the power frequency and still reject power frequency interference. The Model 4025D is designed for portable use in the field; powered via an internal rechargeable battery.
