Dangers Of High Voltage: Common Hazards & Safe Practices

Power Transmission: High voltage is crucial for transmitting power over long distances. When voltage is increased, the current for a given power level is reduced. This is important because power loss due to resistance in the transmission lines is proportional to the square of the current. Therefore, transmitting power at high voltage and low

Emergency Power System Services

In the event of a power outage, a single bad cell in a string of batteries could compromise your entire backup system and leave you without protection. Frequent battery inspections identify weak or failing batteries. Timely assessments of the cell and string state of health helps identify when batteries need replaced to ensure system reliability.

What to do if the battery in the emergency power supply cabinet is over-voltage [PDF]

6 FAQs about [What to do if the battery in the emergency power supply cabinet is over-voltage]

What happens if a power supply fails?

During a failure of the main and emergency power supplies, the battery system will take over. If the battery has been subjected to a period of duty due to power failure, the battery charger is automatically transferred to an equalizing charge on restoration of the power supply and this rapidly charges the battery.

What happens if a battery system is lost?

In the event of loss of the main source, the system automatically changes over to the emergency source. In the event of loss of both the main and emergency source, the battery system will continue to supply the essential consumers served by the distribution board. In this way the essential consumers are maintained for as long as possible.

What is an emergency power switchover?

The purpose of the emergency power switchover is to ensure the disconnection of the household from the grid before the isolated operation is activated. This ensures that maintenance personnel are not endangered by unintentionally fed energy. Depending on the grid operator, the requirements for emergency power switchover can differ.

What is an uninterruptible power supply (UPS) & battery system?

Uninterruptible power supply (UPS) and battery systems explained Most of the emergency power requirements are supplied by the emergency 24V system which consists of a battery distribution board backed up by a separate 24V battery. This provides a smooth changeover to a constant power source upon loss of the ship’s main or emergency power.

Do emergency power systems require lockout?

Some maintenance items may require lockout of other components of the emergency power system, rendering that portion of the emergency system inoperable — if not the entire system. For example, maintenance on the automatic transfer switch (ATS) may require operation in a “bypass” mode.

What type of emergency power supply do I Need?

For reasons of reliability, a diesel engine prime mover coupled to a 3-phase generator and mounted together as one unit (generator set) is the most common type of emergency power supply in use. A large part of maintenance and operational testing revolves around the diesel-driven generator set ( Photo 1 ).
