Our Services

D&G offers full setting calculation and development services for protective relays of all types. Whether for new construction, or retrofit of existing infrastructure, let us engineer accurate and effective protection settings.

With a strong background in utility plant protection, D&G engineers have seen a wide variety of fault events. When a fault occurs we can help analyze the event, isolate the issue, and get repairs underway in a timely manner.

D&G offers protective scheme design services for new facility construction and protection retrofit projects. From single relay replacements, to full main power path upgrades, and everything in between, D&G provides quality designs that provide superior facility protection.

D&G is experienced in performing NERC related engineering studies to ensure our clients' compliance with NERC standards. Specializing in PRC-002, PRC-004, PRC-005, PRC-019, PRC-024, and PRC-025.

For NERC PRC-005 maintenance testing, or new installation acceptance testing, D&G provides full relay testing services for electromechanical, static, and microprocessor protective relays.

D&G can provide commissioning services for newly installed utility plant protective systems including DC control circuits for switchgear/breakers, protective relays, and AC instrumentation transformers. We get new equipment online safely and correctly.

D&G offers turnkey project retrofits for protection upgrades including scoping, design, engineering, demolition, installation, and full commissioning services. Let us deliver quality service from start to finish.

When events happen, and support is needed right away, D&G offers on-call services for event retrieval and support for equipment return to service. D&G is experienced in emergency protective relay replacement, often times with less than 24 hour return to service.
