Electrical testing is essential in the construction, generation, distribution, and maintenance of electrical equipment and lines. From the transformer in the power plant to the circuit breakers in a building, testing and identifying potential issues is necessary in extending the life expectancy and performance of the equipment and power lines. Additionally, these tests help protect against dangerous situations and preserve the quality of the electricity being distributed.
Advanced Test Equipment Rentals identifies electrical test equipment into two categories: industrial electrical and facility power equipment. Industrial electrical equipment focuses on the maintenance of substations and their components. Facility power equipment is intended to measure the power and efficiency of homes, schools, warehouses or any facility wishing to take a closer look at their electricity use.
Why Conduct Electrical Testing?
Electrical testing is paramount to the safety of people and equipment, and efficiency of any business entity for the following reasons:
- Functionality. Electrical tests can unearth faults that otherwise might go undetected for years. Performing preventative maintenance can double life expectancy of electrical systems.
- Safety. Electricians want to discover problems before disasters occur. Periodic inspections will check for the following:
- Fires Prevention: Electrical malfunctions are the leading cause of workplace fires which can result in loss of life and property.
- Shocks: Excess current can travel to human bodies and also behave erratically within the system due to loose wires.
- Surges: Often resulting from on/off switching electronics, surges can result in destruction of equipment.
- Power Quality: Reduce loss of computer data and malfunctions
- IEC Standard Compliance. The following IEC standards ensure adherence to the International Electrotechnical Commission (IEC)
- IEC 60270
- IEC 60335
- IEC 61010
Industrial Electrical test equipment play an integral role in the manufacturing and maintenance of substation components. A substation provides power along cables to towers. Towers in turn power buildings. Transformers, circuit breakers, relay testers and more undergo the following test methods several times before installation in a substation. Over the years, utility companies will continue to test the components for faults and conduct acceptance tests, constantly re-assessing the functionality of their electrical systems.
Protective Relay Test Sets
A protective relay test set allows engineers to simulate faults and monitor the functionality of protective relays, including overcurrent, three-phase, microprocessor-based relays and relays which require phase shifting capabilities. View all protective relay test set models…
Transformer and Motor Testing Equipment
Transformers convert 120 / 240VAC down to a lower AC voltage. Transformer test sets and motor testers monitor the performance of transformers and motors respectively, measuring voltage and current to detect anomalous behavior. See all available equipment…
The term “partial discharge” refers to tiny electrical sparks occurring inside of medium/high voltage electrical devices. Partial discharge monitoring systems discover insulation erosion due to sparks, which may eventually cause insulation failure, the leading cause of total electrical failure.

Circuit Breaker Test Sets
A circuit breaker test set gives technicians data on deviations and changes in a circuit breaker’s role as the safety mechanism in an electrical system. Comparing previous results to current results under the exact same conditions is key to accurately analyzing the state of a circuit breaker. For more on circuit breaker test sets click here...
Hipot Cable Testing
Hipot cable testers send energy down power cables to check for cable faults. If a fault is present in a cable, energy will bounce back to the source. ATEC offers cable testers that generate AC, DC and VLF (very low frequency) power. VLF cable testers specialize in traversing long cables without the need for a massive power supply, providing the necessary energy by operating at a lower frequency. Click here for more on DC Hipot

Industrial Electrical Testing Equipment
Facility power tests are conducted to gauge the electrical efficiency of any building, informing employers what changes they need to make to accommodate more systems or how they can save on their energy bills. These measurements also determine the safety of an electrical environment, revealing to technicians the risk of surges or electrical fires.
A power quality analyzer reveals the electrical efficiency of a system, helping technicians decide how to cut costs or expand electrical infrastructure in the future. Power quality analyzers will also detect how well an electrical system reacts to current, voltage or frequency disturbances commonly found in facility power systems. See all available equipment…
Cable Fault Testing
Cable fault testing identifies periodic or insulation faults in underground cables which may be caused by moisture, sheath cracks, phase contact or other issues. Faults will result in the deterioration of the cable’s resistance and may lead to a voltage breakdown in the future. See all available equipment…
