Standard Metal Enclosed Multiple Step Capacitor Assemblies

Basic Options | Capacitor Units | Quotation/Ordering Information | Constructing a Catalog Number

Gilbert Electrical System metal enclosed capacitor assemblies are designed to meet a wide variety of multiple step capacitor applications for utility and industrial customers.

Standard assemblies are available as low as 300 KVAR per stage and as large as 7200 KVAR per stage for 5 to 15 KV applications (25KV and 35KV assemblies are available as well as higher kvar ratings.):

Multiple Step Capacitor Assemblies (type MSC) offers a well-engineered and efficient way to provide a wide Varity of KVAR and options.

GES-MSC metal enclosed capacitor assemblies can offer cost savings over open-type capacitor and competitive assemblies in several ways:

Proper current limiting reactors are required (provided) in the stages to protect the equipment from back to back switching transients.

Capacitor Units

GES type MSC capacitor assemblies are furnished with field-proven highly reliable all-film capacitors. The capacitors are designed with low operating temperature, reduced tank rupture hazard and are properly fused.

Quoting and Ordering Information

To request a quotation or order GES type MSC capacitor assembly, use the tables below to construct a catalog number, which will describe your requirement.

Table 1. Select the code describing the system voltage from Table 1.

Table 2. Select the code describing the total three phase kvar rating from Table 2.

Table 3. Select the number of switching steps desired.

Table 4. Kvar increment per step.

Note: Add the appropriate step number and KVAR increments to the catalog number.

Table 5. Select the code describing the required bank connection.

Table 6. Select the codes describing the incoming section from Table 6.

Table 7. Select the code describing the switching options.

Table 8. Select the code describes the optional equipment available as standard.

Constructing a Catalog Number

The chart below shows how to construct the catalog number for the series MSC metal-enclosed capacitor assembly with the following requirements:

MSC- Basic letters for series MSC metal enclosed Multiple Step Capacitor assembly

G - Total installed three-phase Kvar from Table 1

315 - Voltage rating code Table 2

7 - Number of steps from Table 3.

450 - Kvar increment from Table 4.

G – Bank connection code; select from Table 5

130 - Incoming section option code; select from Table 6

V - Switch code; select from Table 7

KABGR - Optional equipment codes: select from Table 8

The complete catalog number would be: MSC-G-315-7-450-G-130-V-KABGR

Example: If 3150 kvar is required that is switched in seven steps, one 450 kvar stage and three 900 kvar stage will be provided with a binary switching logic controller that is interfaced with the type of control strategy required (e.g., voltage, VAR, power factor, etc.). Sequence switching will be provided, in this example, as follows:
