Electrical Testing
RAWAFED AL-KHOR’s business focus is dedicated to achieving operational excellence across all our programs and projects. The key principles of operational excellence we apply include:
Primary Testing
Secondary Testing
Functional Testing
Electrical system tests are conducted by specialists in strict accordance with international and national standards. These certified experts, trained under IEC, IEEE, NEMA, and NEC guidelines, are fully equipped to handle nearly any reliability program.
Primary Testing
1.1 Transformer Test
The transformer is a critical component of the electrical system. Our company provides the expertise and testing equipment necessary to perform the key required tests on transformers.
Turn Ratio (Per Tap)
Winding Resistance(Per Tap)
Vector Group
Insulation Resistance
Power Factor (CH, CL, CH-CL)
Oil Break Down Test BDV (ASTM & IEC)
Cooling system test
Protective Devices Testing
Stability Test
Tap Changer (AVR test)

Bushing CT Test (BCT)
VT test
1.2 Grid & SWGR Test
Switches are a key component of the electrical power system. Our company provides the expertise and testing equipment to perform all essential tests on GIS and AIS grids, as well as MV and LV switchgear.
CT & VT test
C.B Test
IR Test
Hi.pot Test
CRM Check
Partial Discharge Test
Functional & Interlock Check
Protection Relay Test
Partial Discharge Test
C.B Circuit Breaker
Gas-Insulated Circuit Breakers (GI C.B.), Air Circuit Breakers (ACB), Oil-Insulated Circuit Breakers, and Vacuum Circuit Breakers (VCB) are the primary switches in an electrical power system. To ensure grid protection and system reliability, multiple tests are performed on these circuit breakers on-site during pre-commissioning, commissioning, and maintenance, including the following:
Conductivity Resistance
Measurement IR Test
Hi. Pot Test
On-off Timing Test
VIDAR Test (VCB only)
Interlock Check
VT - Voltage Transformer Test
A Voltage Transformer (VT) is a key instrument for metering, protection, and isolation in the electrical system. To ensure reliability and compliance, a series of on-site tests are performed on VTs during pre-commissioning, commissioning, and maintenance, including the following:
Ratio Test
Winding Resistance
Measurement IR Test
Burden Measurement
Polarity Check
Earth System Test
The earth system is the first line of protection for humans and electrical equipment. During project design, soil resistivity measurements are performed to calculate fault currents and define earth system specifications. Our company has tested earth systems on many projects using advanced methods, including the Bird’s Eye Method and the 62% Method.
CT - Current Trasnformer
Current Transformers (CT), used alongside Voltage Transformers (VT), are key instruments for metering, protection, and isolation in the electrical system. To ensure reliability and compliance, a range of on-site tests are performed on CTs during pre-commissioning, commissioning, and maintenance, including the following:
Ratio Test
Winding Resistance
Measurement IR Test
Burden Measurement
Polarity Check
Secondary Testing
Secondary testing is a critical procedure for protective devices—such as protection relays, metering relays, transducers, AVR relays, and PLCs—conducted directly on the devices without using CTs, VTs, or other instruments.
Advanced Test
RAWAFED AL-KHOR COMPANY provides extensive experience, technical expertise, and advanced equipment for third-party engineering, electrical equipment testing, and quality assurance/quality control services.
Advanced Secondary Test
The Omicron CMC356 and CMC256, along with the Secondary Injection Kit, are used for testing distance relays, advanced differential relays, and generator protection relays. This secondary injection kit is one of the best tools for testing advanced relays, offering the capability to work with GOOSE-enabled grids.
Advanced Primary Test
The Omicron CPC 100 and its Primary Injection Kit accessories are used for testing the primary side of electrical equipment, including transformers, switchgear, CTs, VTs, and circuit breakers.
Our company also offers additional inspection methods, including online partial discharge testing and earth system assessments.
