Electrical Distribution System in a Data Center: Medium-voltage (MV) and Low-voltage (LV) switchgear

May 12th, 2020 07:06 AM

So far we explored the Electrical Distribution System in a Data Center. The critical supply from the utility / transformer / generator to the load is enabled by various types of power equipment. One of the key components of the critical supply is switchgear.


Medium-voltage (MV) Switchgear

Medium-voltage switchgear is generally located in the power substation of large-capacity data centers (i.e. greater than 1 MW IT load). This equipment is typically fed directly from the utility and usually marks the utility service entrance to the building.

If a MV generator is present, it also feeds the MV switchgear. The following figure shows an example of MV switchgear single line diagram:-

10kV MV Switchgear Single Line Diagram

Other than simply distributing power, the MV switchgear is responsible for disconnecting faults and controlling the MV power distribution system, for example, when isolating a redundant section for maintenance.

Basically medium-voltage switchgear is the assembly of four cubicles as shown in the Figure above: two incoming units (incomers) or main section, outgoing units or feeder section, voltage metering unit, and bus section or tie section/breaker.

The outgoing unit distributes three-phase power to the primary (upstream) side of the MV / LV transformer. Due to safety distances at MV, typically each cubical is limited to only one MV circuit breaker.


The following are some typical electrical parameters for MV switchgear. Values for these parameters vary according to local regulations:


Voltage ratings:-

Two key voltage ratings for MV switchgear are rated voltage and rated lightning impulse voltage (equivalent to the ANSI basic impulse level i.e. BIL). For example, an ANSI MV switchgear solution may have a rated voltage of 15kV and 95kV BIL (i.e. impulse voltage).


Current ratings:-

The rated current of MV switchgear is always specified by the manufacturer. Another key current rating is the rated short-circuit withstand current similar to the North American National Electric Code’s (NEC) short-circuit current rating (SCCR).

For example, an ANSI MV switchgear solution may have a rated current of 1200A and 40kA SCCR.



Low-voltage (LV) Switchgear

Typically LV switchgear / switchboard is located in the electrical room and marks the utility service entrance for data centers less than 1 MW.

An example of LV switchgear is shown in figures below. If a LV generator is used, the generator would feed the LV switchgear. Apart from distributing power, the LV switchgear is responsible for disconnecting faults and controlling the LV power distribution system.

Note that in the case of a medium voltage generator, this transferring function occurs at the medium voltage switchgear level.

In real situation, the single line diagram will look something like this:-

A device known as an Automatic Transfer Switch (ATS) has traditionally been used to switch between utility and generator. However, the current trend is to have LV breakers perform this function in lieu of the ATS device. Also, there is a practice of using PLC logic for switching between utility and generator sources.

The following devices are always assembled in LV switchgear: horizontal busbar, vertical busbar, circuit breakers, meters, switches, surge arresters, relays, etc.

LV switchgear / switchboard installed in a data center is typically a combination of some of the following functional units: incoming feeder from the secondary side of the MV / LV transformer or LV generators, power control center (PCC, i.e. for downstream UPS), motor control center (MCC, i.e. for pumps), the power factor correction/harmonic filtering and the bus connections.


The following are key electrical parameters of the LV switchgear. The values for these parameters vary according to local regulations:


Voltage ratings:-

Two key voltage ratings for LV switchgear are rated voltage and rated lightning impulse voltage. ANSI does not specify the impulse voltage for LV switchgear. For example, an IEC LV switchboard solution may have a rated voltage of 690V and 12kV rated impulse withstand voltage.


Current ratings:-

The rated current of LV switchgear is always specified by the manufacturer. Another key current rating is the rated short-circuit withstand current similar to the North American National Electric Code’s (NEC) short-circuit current rating (SCCR).

For example, an IEC switchgear solution may have a rated current of 5000A and 85kA rated short-circuit withstand current.

Electrical Distribution System in a Data Center

March 12th, 2020 08:19 AM

There are many different loads in the data center, such as IT devices, air conditioners (CRAC Units), pumps, lighting, etc. The critical supply from the utility / transformer / generator to the load is enabled by various types of power equipment. We are going to illustrate these equipment that are critical and without which it would not be possible to operate the data center.

Figure 1 is a block diagram of an electrical distribution system showing the name and the typical location of the electrical distribution equipment in a data center and the power flow path (Uptime Institute Tier Level II, N+1 Design) . This diagram is only an example of an electrical architecture and attempts to include all the possible major types of equipment used and their typical location in a data center. In the real world, a typical data center electrical design has much more complexity and diversity than that in this diagram.

Uptime Institute Tier II, N+1 Design

Figure 1 

Uptime Institute Tier III Design

Uptime Institute Tier IV, 2N+1 Design

Tracing the flow of power along its path (starting from the utility to the IT load) in the figure 1 above. It shows 8 essential facilities are critical for the power supply. This facilities distribute power to the downstream loads and also protect the power distribution system in the data center:

• Medium-voltage switchgear
• MV/LV transformer
• Low-voltage switchgear / switchboard / automatic transfer switch (ATS)
• UPS system with input/output switchboard and UPS distribution switchboard
• Power distribution Units (PDUs) and remote power panels (RPPs)
• Busway
• Panelboard
• Rack PDUs (rPDUs) / outlet strips

All facilities above, except for rack PDUs (rPDUs), are considered to be assemblies containing circuit breakers, switches, various types of relays, buses and connections, and control and auxiliary devices. Each device is optimized for long life and ease of maintenance.

The IEC 61947 & IEC 62271, which specifies the HV and LV switchgear terminology, considers switchboard to be the same as switchgear. For some regions like, North American, switchgear and switchboard are specified differently by ANSI and UL standards.
