59738 — Schneider Electric ViP30 Numerical Protection Relay
The Schneider Electric ViP30 is a compact numerical protection relay providing overcurrent (50/51), earth fault (50N/51N), directional overcurrent, and directional earth fault protection functions in a standard 4U flush-panel relay case, designed for medium-voltage feeder, motor, and transformer protection in industrial and utility applications. The ViP30 uses digital signal processing of CT and VT secondary inputs to compute protection functions with measurement accuracy of 1%, providing calibrated protection settings that can be applied directly from the relay's characteristic curves without site measurement correction factors. The relay's front panel LCD display shows real-time measured values and protection status, providing local monitoring capability without a separate measurement display.
The ViP30's protection setting flexibility covers independent time-overcurrent (IDMT) characteristics including Normal Inverse, Very Inverse, Extremely Inverse, and Definite Time — matching the full range of IDMT characteristics encountered in IEC and ANSI protection coordination studies used by Saudi electrical engineers. The relay's Modbus RTU communication port connects to substation SCADA and DCS systems for remote tripping, blocking, and event record retrieval. The ViP30 is mounted in a standard 4U flush panel case with drawout option, enabling relay testing with the circuit connected via the drawout test plug system without primary circuit de-energisation.
In Saudi Arabia, the ViP30 KSA serves industrial MV switchgear protection applications where the full featured Sepam relay family is over-specified for the protection requirement and a simpler, lower-cost numerical relay provides the necessary functions. ARAMCO's non-critical process MV feeder protection, SABIC's secondary utility distribution MV switchgear, and industrial facility 13.8 kV and 33 kV switchgear assembled by Saudi panel builders represent the primary ViP30 application segments. The relay's compact format is also valued in upgrading older electromechanical relay panels where the 4U case fits in existing relay panel cutouts.
Razz Middle East supplies ViP30 relays with protection setting coordination studies, relay testing, and SCADA integration commissioning for MV switchgear projects across Saudi Arabia.

Key Features & Benefits
- Four IDMT characteristic options (Normal Inverse, Very Inverse, Extremely Inverse, Definite Time) to IEC 60255-151 and ANSI equivalents cover all coordination curves encountered in Saudi industrial MV protection studies.
- Directional overcurrent and directional earth fault functions enable selective protection in meshed MV network topologies and generator-paralleled bus configurations at industrial facilities.
- Modbus RTU communication enables remote tripping, blocking, and event record retrieval from plant DCS and substation SCADA systems without the engineering complexity of IEC 61850 implementations.
- 4U standard case with drawout option allows relay testing via test plug with primary circuit connected, enabling periodic relay maintenance without MV circuit de-energisation and with minimal SCADA downtime.
- 1% measurement accuracy for protection and metering functions allows relay trip settings to be applied directly from current and voltage ratio calculations without measurement correction factors.
- Front panel LCD real-time measurement display shows phase currents, earth fault current, and protection function status, providing local monitoring during commissioning and routine site inspection visits.
- Compact numerical relay replaces older electromechanical overcurrent relay panels in upgrade projects at existing Saudi industrial MV switchgear, fitting in the same 4U panel cutout without mechanical modification.
Industrial Applications in Saudi Arabia
- Industrial MV feeder protection in 13.8 kV and 33 kV switchgear at ARAMCO facility non-critical distribution feeders, where ViP30's cost-effective numerical protection replaces aging electromechanical relays.
- SABIC secondary utility distribution MV switchgear overcurrent and earth fault protection at Jubail petrochemical complex sub-distribution substations where simple feeder protection is the sole requirement.
- Saudi industrial MV switchgear manufacturer relay panel assembly for commercial, industrial, and infrastructure projects, where ViP30's compact format and straightforward Modbus integration simplify panel engineering.
- Motor protection relay for 3.3 kV and 6.6 kV motors at industrial facilities where the ViP30 provides overcurrent, earth fault, and overload protection in a single compact relay.
- Transformer protection relay for small distribution transformers in industrial plant sub-substations, where overcurrent and earth fault protection on both HV and LV sides is provided by ViP30 relays.
- Electromechanical relay panel upgrade projects at Saudi industrial MV switchgear, where ViP30 replaces aging CO/CDG mechanical relays in the existing relay panel cutout with numerical protection and Modbus communication.
- Renewable energy solar farm LV/MV interconnection protection at REPDO project sites, where ViP30 provides islanding detection and overcurrent protection for the solar farm's MV connection to the SEC grid.
