Frequently Asked Questions

Switchgear, Switchboard & Panel Board Testing

What is a switchboard?

A switchboard is a ground-mounted unit for systems using 600V or lower voltage. It distributes power across multiple sources, often working in tandem with switches and indicators. There is also a difference between switchboards, switchgear, and panelboards.

How do you clean an electric switchboard?

An electric switch board can be kept clean with regular operation and use. However, routine cleaning by professionals is a recommended service. Contact us to schedule switchboard cleaning and testing.



How do you test an electric panel?

An electric panel is tested by conducting a series of electrical tests. These tests are performed to ensure all elements of the panel are working properly and efficiently. Those tests include bolted connection, insulation, dielectric withstand, instrument transformer, circuit breaker and switch, control power transfer scheme, and metering electrical tests. Schedule testing here.



How often should the switchboards be inspected and tested?

Switchboards should be inspected about once a year. You should always look for signs of failure like burning odor, tripped breakers, and a high number of blown fuses that may indicate it is time for switchboard maintenance.



NETA Acceptance Testing

What is NETA testing?

NETA testing is meant to evaluate how electrical equipment and systems are functioning. The intention is to establish reliability and safety for all electrical systems. NETA stands for the InterNational Testing Association and they provide these guidelines for electrical testing.

Is NETA testing required?

Though not required, NETA testing is a strongly recommended and valued indicator of an electrical system. NETA certified testing companies like Power Products & Solutions provide a complete understanding of the requirements and needs of your business.



How much does NETA testing cost?

NETA testing varies depending on situation. Contact us for an estimate.



Battery Testing & Services

How much resistance should a battery have?

Your battery should not have any resistance. If it has too much resistance, it will waste energy and fail to draw adequate electrical current.

What is a low resistance test?

A low resistance test measures the rate at which electrical energy converts to heat and whether the resistance impacts a battery's performance. This identifies if there is energy loss in the electrical device. Contact us for a low resistance test.



What is float voltage?

Float voltage is the energy level that must be maintained to remain a charged battery over a period of time. Charger float testing measures how well each battery accepts power.

What is battery equalization voltage?

Battery equalization voltage is when the charge is elevated above the float voltage. This allows all cells to accept more power and improve the weak performing cells.



MV Cable

What is MV cable?

A medium voltage (MV) cable is between 5 kV to 35 kV which accounts for many industrial and electrical utility applications.

How do you test an MV cable?

MV cables should be tested by professionals. Tests like tan delta cable testing are common ways of measuring cable longevity. Contact us for MV cable testing.



How do you test for Tan Delta?

Tan delta testing uses incremental voltage adjustments to accurately measure MV cable insulation. During this test, your system will be offline and the technician will conduct testing that aligns with IEEE (Institute of Electrical and Electronics Engineers) standards.

What is battery equalization voltage?

Battery equalization voltage is when the charge is elevated above the float voltage. This allows all cells to accept more power and improve the weak performing cells.



Arc Flash Study

Who can perform an arc flash study?

Arc flash studies should be performed by experienced, qualified electrical technicians. NETA-certified testing agencies go through rigorous testing to ensure the best quality and safest electrical work.

When is an arc flash study required?

Arc flash studies should be conducted every three years. Studies should also take place when there are changes to the electrical utility or when considering modifications. Lastly, these studies are appropriate when an insurance policy is ready for renewal or there is a required safety audit.



What is an arc flash coordination study?

An arc flash coordination study analyzes and evaluates to determine potential or existing electrical system hazards. It includes a series of calculations, recommendations, and evaluations to ensure electrical safety. Contact us to schedule an arc flash study.

What is battery equalization voltage?

Battery equalization voltage is when the charge is elevated above the float voltage. This allows all cells to accept more power and improve the weak performing cells.
